US Petroleum Holdings, information about gas, oil and petroleum
The UK now exports quantities of crude oil and is acknowledged for expertise in the area of deep-water technology – using advanced engineering techniques for extracting a higher proportion of oil from each field. This technique was unknown twenty years ago. Consequently, UK specialists are in demand all over the world.
The UK Continental Shelf (UKCS) is facing significant challenges as the province matures. Recovering oil and gas from the North Sea and the Atlantic Margin (the area of water to the west of Shetland and the north of the Hebrides) is a highly technical, complex, dangerous and expensive job. As supplies from larger oil fields run out, smaller, more expensive fields are being exploited. UK oil companies have to be inventive and invest in safe and efficient techniques to remain competitive.
The UK still has substantial recoverable reserves of oil and gas, potentially exceeding the amount already produced. However, many existing, large producing fields are well into decline and discoveries are becoming fewer and smaller or have significant associated technical challenges.
Current trends
As the UK’s oil fields mature, the industry’s focus has shifted from searching for new oil discoveries to continuing the productivity of mature fields, as well as developing smaller fields that were not previously considered commercially viable. This trend has prompted major oil companies to begin selling some of their mature UKCS assets in favour of other regions of the world. Smaller, independent oil companies have been acquiring these UKCS assets.
Natural gas is the UK’s largest source of primary energy, supplying over 40% of the country’s total energy needs. It is used as both a domestic and industrial fuel. It generates electricity to provide heat and power for homes and industries, and is feedstock for chemicals, pharmaceuticals and other products.
The UK is currently the world’s fourth largest producer of natural gas and has more than 200 offshore fields in production around Great Britain. The greatest concentrations of gas are found in the southern sector of the North Sea, but significant volumes are also produced from the central and
Pipeline diplomacy petroleum
The Baku-Tbilisi-Ceyhan pipeline was built to transport crude oil and the Baku-Tbilisi-Erzurum pipeline (South Caucasus Pipeline) was built to transport natural gas from the western side of the Caspian Sea to the Mediterranean Sea bypassing Russian pipelines and thus Russian control. Following the construction of the pipelines the United States and the European Union proposed extending them by means of the proposed Trans-Caspian Oil Pipeline and the Trans-Caspian Gas Pipeline under the Caspian Sea to oil and gas fields on the eastern side of the Caspian Sea in Turkmenistan and Kazakhstan. In 2007, Russia signed agreements with Turkmenistan and Kazakhstan to connect their oil and gas fields to the Russian pipeline system effectively killing the undersea route.
China has completed the Kazakhstan-China oil pipeline from the Kazakhstan oil fields to the Chinese Alashankou-Dushanzi Crude Oil Pipeline in China. China is also working on the Kazakhstan-China gas pipeline from the Kazakhstan gas fields to the Chinese West-East Gas Pipeline in China.
Analysis source rocks petroleum geology
Analysis of source rocks
In terms of source rock analysis, several facts need to be established. Firstly, the question of whether there actually is any source rock in the area must be answered. Delineation and identification of potential source rocks depends on studies of the local stratigraphy, palaeogeography and sedimentology to determine the likelihood of organic-rich sediments having been deposited in the past.
If the likelihood of there being a source rock is thought to be high, the next matter to address is the state of thermal maturity of the source, and the timing of maturation. Maturation of source rocks (see diagenesis and fossil fuels) depends strongly on temperature, such that the majority of oil generation occurs in the 60° to 120°C range. Gas generation starts at similar temperatures, but may continue up beyond this range, perhaps as high as 200°C. In order to determine the likelihood of oil/gas generation, therefore, the thermal history of the source rock must be calculated. This is performed with a combination of geochemical analysis of the source rock (to determine the type of kerogens present and their maturation characteristics) and basin modelling methods, such as back-stripping, to model the thermal gradient in the sedimentary column.
Uses of Gas Oil
Us Petroleum Holdings Oil has many uses; it heats homes and businesses and fuels trucks, ships and some cars. A small amount of electricity is produced by diesel, but it is more polluting and more expensive than natural gas. It is often used as a backup fuel for peaking power plants in case the supply of natural gas is interrupted or as the main fuel for small electrical generators. In Europe the use of diesel is generally restricted to cars (about 40%), SUVs (about 90%), and trucks (virtually all). The market for home heating using fuel oil, called heating oil, has decreased due to the widespread penetration of natural gas. However, it is very common in some areas, such as the Northeastern United States.
Residual fuel oil is less useful because it is so viscous that it has to be heated with a special heating system before use and it contains relatively high amounts of pollutants, particularly sulfur, which forms sulfur dioxide upon combustion. However, its undesirable properties make it very cheap. In fact, it is the cheapest liquid fuel available. Since it requires heating before use, residual fuel oil cannot be used in road vehicles, boats or small ships, as the heating equipment takes up valuable space and makes the vehicle heavier. Heating the oil is also a delicate procedure, which is inappropriate to do on small, fast moving vehicles. However, power plants and large ships are able to use residual fuel oil.
Residual fuel oil was used more frequently in the past. It powered boilers, railroad locomotives and steamships. Locomotives now use diesel, steamships are still used however are not as common as they were previously due to their higher operating costs, (most LNG carriers use steam plants as boil off gas emitted from the cargo can be used as a fuel source), and most boilers now use heating oil or natural gas. However, some industrial boilers still use it and so do a few old buildings, mostly in New York City. Residual fuel’s use in electricity generation has also decreased. In 1973, residual fuel oil produced 16.8% of the electricity in the United States. By 1983, it had fallen to 6.2%, and as of 2005, electricity production from all forms US Petroleum Holdings of petroleum, including diesel and residual fuel, is only 3% of total production. The decline is the result of price competition with natural gas and environmental restrictions on emissions. For power plants, the costs of heating the oil, extra pollution control and additional maintenance required after burning it often outweigh the low cost of the fuel. Burning fuel oil, particularly residual fuel oil, also produces much darker smoke than natural gas, which affects the perception of the plant by the community.
Heavy fuel oils continue to be used in the boiler “lighting up” facility in every coal-fired power plant, of which there are a small number in the UK and dozens in China. Although on an enormous scale, it is analogous to lighting kindling to start a fire – without performing this simple function it is difficult to begin the large-scale combustion process.
The chief drawback to residual fuel oil is its high initial viscosity, particularly in the case of No. 6 oil, which requires a correctly engineered system for storage, pumping, and burning. Though it is still usually lighter than water (with a specific gravity usually ranging from 0.95 to 1.03) it is much heavier and more viscous than No. 2 oil, kerosene, or gasoline. No. 6 oil must, in fact, be stored at around 100°F (37.8°C) heated to 150°F (65.6°C)–250°F (121.1°C) before it can be easily pumped, and in cooler temperatures it can congeal into a tarry semisolid. The flash point of most blends of No. 6 oil is, incidentally, about 150°F (65.6°C). Attempting to pump high-viscosity oil at low temperatures was a frequent cause of damage to fuel lines, furnaces, and related equipment which were often designed with lighter fuels in mind.
(For comparison, BS2869 Class G Heavy Fuel Oil behaves in similar fashion, requiring storage at 104°F (40°C), pumping at around 122°F (50°C) and finalising for burning at around 194°F (90°C) / 248°F (120°C).)
Most of the facilities which historically burned No. 6 or other residual oils were industrial plants and similar facilities constructed in the early or mid 20th century, or which had switched from coal to oil fuel during the same time period. In either case, residual oil was seen as a good prospect because it was cheap and readily available, even though it provided less energy per litre than lighter fuels. Most of these facilities have subsequently been closed and demolished, or have replaced their fuel supplies with a simpler one such as gas or No. 2 oil. The high sulfur content of No. 6 oil– up to 3% by weight in some extreme cases– had a corrosive effect on many heating systems (which were usually designed without adequate corrosion protection in mind), shortening their lifespans and increasing the polluting effects. This was particularly the case in furnaces that were regularly shut down and allowed to go cold; the internal condensation produced sulfuric acid.
Environmental cleanups at such facilities are frequently complicated by the use of asbestos insulation on the fuel feed lines. No. 6 oil is very persistent, and does not degrade rapidly. Its viscosity and stickiness also make remediation of underground contamination very difficult, since it reduces the effectiveness of methods such as air-stripping.
When released into water, such as a river or ocean, residual oil tends to break up into patches or tarballs– mixtures of oil and particulate matter such as silt and floating organic matter- rather than form a single slick. An average of about 5-10% of the material will evaporate within hours of the release, primarily the lighter hydrocarbon fractions. The remainder will then often sink to the bottom of the water column.
USPetroleum what is petroleum?
US Petroleum Holdings colaborate with the us definition of Petroleum (Latin Petroleum f. Holdings Latin petra (f. Greek ????? – rock) + Latin oleum (f. Greek ?????? – oil)) or crude oil is a naturally occurring, flammable liquid found in rock formations in the Earth consisting of a complex mixture of hydrocarbons of various lengths, plus other organic compounds. The proportion of hydrocarbons in the mixture is highly variable and ranges from as much as 97% by weight in the lighter oils to as little as 50% in the heavier oils and bitumens.
The hydrocarbons in crude oil are mostly alkanes, cycloalkanes and various aromatic hydrocarbons while the other organic compounds contain nitrogen, oxygen and sulfur, and trace amounts of metals such as iron, nickel, copper and vanadium. The exact molecular composition varies widely from formation to formation but the proportion of chemical elements vary over fairly narrow limits as follows:[1]
| Carbon | 83-87% |
| Hydrogen | 10-14% |
| Nitrogen | 0.1-2% |
| Oxygen | 0.1-1.5% |
| Sulfur | 0.5-6% |
| Metals | <1000 ppm |
Crude oil varies greatly in appearance depending on its composition. It is usually black or dark brown (although it may be yellowish or even greenish). In the reservoir it is usually found in association with natural gas, which being lighter forms a gas cap over the petroleum, and saline water, which being heavier generally floats underneath it. Crude oil may also be found in semi-solid form mixed with sand, as in the Athabasca oil sands in Canada, where it may be referred to as crude bitumen.
Petroleum is used mostly, by volume, for producing fuel oil and gasoline (petrol), both important “primary energy” sources. [2] 84% by volume of the hydrocarbons present in petroleum is converted into energy-rich fuels (petroleum-based fuels), including gasoline, diesel, jet, heating, and other fuel oils, and liquefied petroleum gas. [3]
Due to its high energy density, easy transportability and relative abundance, it has become the world’s most important source of energy since the mid-1950s. Petroleum is also the raw material for many chemical products, including pharmaceuticals, solvents, fertilizers, pesticides, and plastics; the 16% not used for energy production is converted into these other materials.
Petroleum is found in porous rock formations in the upper strata of some areas of the Earth’s crust. There is also petroleum in oil sands (tar sands). Known reserves of petroleum are typically estimated at around 140 km³ (1.2 trillion barrels) without oil sands [4], or 440 km³ (3.74 trillion barrels) with oil sands [5]. However, oil production from oil sands is currently severely limited. Consumption is currently around 84 million barrels per day, or 3.6 km³ per year. Because of reservoir engineering difficulties, recoverable oil reserves are significantly less than total oil-in-place. At current consumption levels, and assuming that oil will be consumed only from reservoirs, known reserves would be gone around 2039, potentially leading to a global energy crisis. However, this ignores any new discoveries, rapidly increasing consumption in China, India, and other developing nations; using oil sands, using synthetic petroleum, and other factors which may extend or reduce this estimate.
Biogenic theory
Most geologists view crude oil and natural gas as the product of compression and heating of ancient organic materials over geological time. Oil is formed from the preserved remains of prehistoric zooplankton and algae which have been settled to the sea (or lake) bottom in large quantities under anoxic conditions. Terrestrial plants, on the other hand, tend to form coal. Over geological time this organic matter, mixed with mud, is buried under heavy layers of sediment. The resulting high levels of heat and pressure cause the organic matter to chemically change during diagenesis, first into a waxy material known as kerogen which is found in various oil shales around the world, and then with more heat into liquid and gaseous hydrocarbons in a process known as catagenesis.
Geologists often refer to an “oil window” which is the temperature range that oil forms in—below the minimum temperature oil remains trapped in the form of kerogen, and above the maximum temperature the oil is converted to natural gas through the process of thermal cracking. Though this happens at different depths in different locations around the world, a ‘typical’ depth for the oil window might be 4–6 km. Note that even if oil is formed at extreme depths, it may be trapped at much shallower depths, even if it is not formed there (the Athabasca Oil Sands is one example).
Hydrocarbon trap.
Hydrocarbon trap.
Because most hydrocarbons are lighter than rock or water, these often migrate upward through adjacent rock layers until they either reach the surface or become trapped beneath impermeable rocks, within porous rocks called reservoirs. However, the process is not straightforward since it is influenced by underground water flows, and oil may migrate hundreds of kilometres horizontally or even short distances downward before becoming trapped in a reservoir. Concentration of hydrocarbons in a trap forms an oil field, from which the liquid can be extracted by drilling and pumping.
Three conditions must be present for oil reservoirs to form: first, a source rock rich in organic material buried deep enough for subterranean heat to cook it into oil; second, a porous and permeable reservoir rock for it to accumulate in; and last a cap rock (seal) or other mechanism that prevents it from escaping to the surface. Within these reservoirs fluids will typically organize themselves like a three-layer cake with a layer of water below the oil layer and a layer of gas above it, although the different layers vary in size between reservoirs.
The vast majority of oil that has been produced by the earth has long ago escaped to the surface and been biodegraded by oil-eating bacteria. Oil companies are looking for the small fraction that has been trapped by this rare combination of circumstances. Oil sands are reservoirs of partially biodegraded oil still in the process of escaping, but contain so much migrating oil that, although most of it has escaped, vast amounts are still present – more than can be found in conventional oil reservoirs. On the other hand, oil shales are source rocks that have never been buried deep enough to convert their trapped kerogen into oil.
The reactions that produce oil and natural gas are often modeled as first order breakdown reactions, where kerogen is broken down to oil and natural gas by a set of parallel reactions, and oil eventually breaks down to natural gas by another set of reactions. The first set was originally patented in 1694 under British Crown Patent No. 330 covering,
“a way to extract and make great quantityes of pitch, tarr, and oyle out of a sort of stone.”
The latter set is regularly used in petrochemical plants and oil refineries.
Uses of Fuel
From Wikipedia
Petroleum, in some form or other, is not a substance new in the world’s history. More than four thousand years ago, according to Herodotus and confirmed by Diodorus Siculus, asphalt was employed in the construction of the walls and towers of Babylon; there were oil pits near Ardericca (near Babylon), and a pitch spring on Zacynthus.[10] Great quantities of it were found on the banks of the river Issus, one of the tributaries of the Euphrates. Ancient Persian tablets indicate the medicinal and lighting uses of petroleum in the upper levels of their society.
The earliest known oil wells were drilled in China in 347 CE or earlier. They had depths of up to about 800 feet (244 m) and were drilled using bits attached to bamboo poles.[11] The oil was burned to evaporate brine and produce salt. By the 10th century, extensive bamboo pipelines connected oil wells with salt springs. The ancient records of China and Japan are said to contain many allusions to the use of natural gas for lighting and heating. Petroleum was known as burning water in Japan in the 7th century. [10]
The Middle East petroleum industry was established by the 8th century, when the streets of the newly constructed Baghdad were paved with tar, derived from easily accessible petroleum from natural fields in the region. In the 9th century, oil fields were exploited in the area around modern Baku, Azerbaijan, to produce naphtha. These fields were described by the geographer Masudi in the 10th century, and by Marco Polo in the 13th century, who described the output of those wells as hundreds of shiploads. Petroleum was distilled by Persian chemist al-Razi in the 9th century, producing chemicals such as kerosene in the al-ambiq (alembic). [12] (See also: Alchemy (Islam), Islamic science, and Timeline of science and technology in the Islamic world.)
The earliest mention of American petroleum occurs in Sir Walter Raleigh’s account of the Trinidad Pitch Lake in 1595; whilst thirty-seven years later, the account of a visit of a Franciscan, Joseph de la Roche d’Allion, to the oil springs of New York was published in Sagard’s Histoire du Canada. A Russian traveller, Peter Kalm, in his work on America published in 1748 showed on a map the oil springs of Pennsylvania. [10]
In 1711 the Greek physician Eyrini d’Eyrinis discovered asphalt at Val-de-Travers, (Neuchâtel). He established a bitumen mine de la Presta there in 1719 that operated until 1986. [13][14]
Oil sands were mined from 1745 in Merkwiller-Pechelbronn, Alsace under the direction of Louis Pierre Ancillon de la Sablonnière, by special appointement of Louis XV.[15] The Pechelbronn oil field was active until 1970, and was the birth place of companies like Antar and Schlumberger. The first modern refinery was built there in 1857.[15]
The modern history of petroleum began in 1846 with the discovery of the process of refining kerosene from coal by Nova Scotian Abraham Pineo Gesner.
Ignacy ?ukasiewicz improved Gesner’s method to develop a means of refining kerosene from the more readily available “rock oil” (“petr-oleum”) seeps in 1852 and the first rock oil mine was built in Bóbrka, near Krosno in Galicia in the following year. These discoveries rapidly spread around the world, and Meerzoeff built the first Russian refinery in the mature oil fields at Baku in 1861. At that time Baku produced about 90% of the world’s oil.
Oil field in California, 1938.
The first commercial oil well drilled in North America was in Oil Springs, Ontario, Canada in 1858, dug by James Miller Williams. The US petroleum industry began with Edwin Drake’s drilling of a 69-foot (21 m) oil well in 1859, on Oil Creek near Titusville, Pennsylvania, for the Seneca Oil Company (originally yielding 25 barrels a day, by the end of the year output was at the rate of 15 barrels). The industry grew slowly in the 1800s, driven by the demand for kerosene and oil lamps. It became a major national concern in the early part of the 20th century; the introduction of the internal combustion engine provided a demand that has largely sustained the industry to this day. Early “local” finds like those in Pennsylvania and Ontario were quickly outpaced by demand, leading to “oil booms” in Texas, Oklahoma, and California.
Early production of crude petroleum in the United States: [10]
- 1859: 2,000 barrels (~340 t)
- 1869: 4,215,000 barrels (~721,000 t)
- 1879: 19,914,146 barrels (~3,410,000 t)
- 1889: 35,163,513 barrels (~6,020,000 t)
- 1899: 57,084,428 barrels (~9,770,000 t)
- 1906: 126,493,936 barrels (~21,600,000 t)
By 1910, significant oil fields had been discovered in Canada (specifically, in the province of Ontario), the Dutch East Indies (1885, in Sumatra), Iran (1908, in Masjed Soleiman), Peru, Venezuela, and Mexico, and were being developed at an industrial level.
Even until the mid-1950s, coal was still the world’s foremost fuel, but oil quickly took over. Following the 1973 energy crisis and the 1979 energy crisis, there was significant media coverage of oil supply levels. This brought to light the concern that oil is a limited resource that will eventually run out, at least as an economically viable energy source. At the time, the most common and popular predictions were always quite dire, and when they did not come true, many dismissed all such discussion. The future of petroleum as a fuel remains somewhat controversial. USA Today news (2004) reports that there are 40 years of petroleum left in the ground. Some[citation needed] argue that because the total amount of petroleum is finite, the dire predictions of the 1970s have merely been postponed. Others[citation needed] claim that technology will continue to allow for the production of cheap hydrocarbons and that the earth has vast sources of unconventional petroleum reserves in the form of tar sands, bitumen fields and oil shale that will allow for petroleum use to continue in the future, with both the Canadian tar sands and United States shale oil deposits representing potential reserves matching existing liquid petroleum deposits worldwide.
Today, about 90% of vehicular fuel needs are met by oil. Petroleum also makes up 40% of total energy consumption in the United States, but is responsible for only 2% of electricity generation. Petroleum’s worth as a portable, dense energy source powering the vast majority of vehicles and as the base of many industrial chemicals makes it one of the world’s most important commodities. Access to it was a major factor in several military conflicts including World War II and the Persian Gulf Wars of the late twentieth and early twenty-first centuries. The top three oil producing countries are Saudi Arabia, Russia, and the United States. About 80% of the world’s readily accessible reserves are located in the Middle East, with 62.5% coming from the Arab 5: Saudi Arabia (12.5%), UAE, Iraq, Qatar and Kuwait. However, with today’s oil prices, Venezuela has larger reserves than Saudi Arabia due to crude reserves derived from bitumen.
US Petroleum Holdings: Business Model
Our Business Model & Strategy:
There is no doubt that the trend in the Oil and Natural Gas market is toward higher and higher prices. The contributing factors for this are many and extremely diverse, running from political uncertainty to increased global consumption. We believe, US Petroleum Holdings, as most analysts do, that this trend will continue throughout the decade and through the next. Suffice it to say that we are in the right business, which under current circumstances will remain resilient to many of the dangerous economic forces that may arise.

EXECUTIVE SUMMARY
The prospects that have been evaluated all represent either un-tapped proven reserves or re-entry or rejuvenation projects of formerly producing wells in the South Eastern United States. As technology US Petroleum Holdings has continued to improve, old wells and old fields that were once too dangerous, too unproductive or “empty” can be reopened and produce economically. These wells are preferred because they are already along the gas and oil pipeline routes that crisscross the United States (i.e. infrastructure costs to monetize new finds in these old wells are minimal).
These investments represent late-stage investment which mitigates the riskUS Petroleum Holdings to investors and the time to production on these wells is shorter than if investments were made in the early stages.
Houston Farm Project
History
The Houston Farms #1 well was drilled by Midwest Oil Company US Petroleum Holdings in 1960 to a total depth of 16,085 ft. The Lower Frio, the main objective at 16,000 ft. was wet and non-productive, so the well was considered a dry hole. While drilling the well, core sample of various Upper Frio sands between 10,000 – 12,000 ft. were taken and indicated condensate (gas) pay. Prior to plugging and abandonment, several of these Upper Frio sands were tested and they showed to be productive. The well was never completed, most likely due to nominal gas prices and/or the lack of a gas market. With Natural Gas prices at the time only a few pennies per MCF of gas, it was not economical to set several miles of pipeline to transport for just one well. Consequently, the well was plugged and abandoned. US Petroleum Holdings
The Frio Deep-Seated Salt Dome Fields lie south and southeast of Houston in Brazoria, Ford Bend, Harris, Galveston and Chambers counties along the Texas coast, US Petroleum Holdings.
Collectively, the Frio Deep-seated Salt Dome Fields are significant because their cumulative yields exceed those of any other producing formation in Southeast Texas. From the early 1930’s through 1982, the fields reported a combined cumulative production in excess of 2.3 billion barrels of oil, and at the end of 1993, the figure surpassed 2.4 billion barrels.
Although the most prolific fields were found in the 1930’s (15 major discoveries), development of the play continued into the 1940’s and 1950’s, and centered in Chambers and Brazoria counties, US Petroleum Holdings, because of the proximity to the Danbury Dome, Hoskins Mound and the apparent deeper seated salt diaper over the Chocolate Bayou field.
By 1982, engineers set recoverable reserves for Frio reservoirs of the deep-domes play at nearly 4 billion barrels of oil. By the end of 1993 the fields had yielded more than 2.4 billion barrels.
In the 1950’s three new areas became productive and were called Chocolate Bayou Upper Frio (Brazoria County, 1950), Trinity Bay Frio 12 (Chambers County, 1951), and Chocolate Bayou Alibel (Brazoria County, 1952).
During the last half of the 20th century, the Chocolate Bayou Field has increased in aerial extent and multiple sand packages stacked all the way down to the 15,000 ft. Lower Frio Marker. Several major oil companies and numerous independent exploration companies have discovered over 55 different horizons (pay zones) within the Chocolate Bayou Field. The cumulative production of both gas and oil within this field is ENORMOUS!
Multiple Oligocene Frio Gas Sands have been identified in the well by log and core analysis. Sands are located within the existing casing between 10,000 and 12,200 ft. The primary objective is to complete the 12,000 ft. series of sands. A future plugback would complete the 10,000 ft. series of sands.
A second well on the property will be drilled to the Miocene Gas Sands between 5,100 and 7,000 ft. These sands show as productive as in the Houston Farms #1 well. The well will “twin” the Houston Farms #1 location for the shallower objectives.
Geological estimation of total reserves: 350,000 barrels of oil and 15 Billion cubic feet of Natural Gas.
Estimated Payout: somewhere between 100 – 120 barrels of crude oil per day.
