Potential future U.S. oil and gas resources


Reduce the impact of the average field size, then that rate will likely continue to grow. 4 lay wrapped head drum 30OOl7O030O00 three remaining oil and gas fields, reserves of conventional oil and gas fields after the discovery of growth,ralph lauren pas cher, made the final extraction volume estimates are generally increased. Increase in reserves (increase the amount of reserves mouth II) is the expansion of oil and gas fields from the edge of the existing wells and infill wells to improve oil and gas geological reserves of original oil recovery and new reservoir, (shallow, deep and between reservoirs) be. Many of the latest estimates of the average results show that in the remaining conventional oil and gas yet to be developed, there will be 60 and 45 and the oil and gas from existing oil and gas fields (discovered before 1990). In a l988 l97-year period, base throughout the United States reserves growth accounted for 86 new oil reserves and natural gas reserves and new 82 and. According to the Energy Information Administration reported that in 1977, before U.S. oil and gas fields found in 48 states in 1977, an increase in reserves during the period l988) eleven Oi plus dock a BU> type type type great little foreign oil and gas information length of 26 million tons (18.6 billion barrels). In the meantime, the newly discovered oil and gas fields to add up to 700 million tons of crude oil reserves (51 billion barrels). Nearly 45% of the total reserve additions from the production history of at least 45 years old oil reserve growth. In recognition of the existing reservoir (back to the beginning of this century found that the oil and gas fields) under normal conditions contains a large number of oil and gas was flowing state, and thus the trend of reserve growth was increased, this trend is the recent and future increases to an increased reserves major factor. Bureau of Economic Geology of the 1970s and 1980s, studies have shown that the reservoir in Texas about 4.8 billion tons (35o billion barrels) in conventional conditions, the residual oil can flow. U.S. Department of Energy by inference, nationwide domestic moving residual oil may be over 13.7 billion tons (1,000 billion barrels). Natural gas also can be used for similar analysis. In 1988 the U.S. Department of Energy made a study of the natural gas resources, estimated reserves of conventional natural gas in existing fields increased the amount of 6.42637 trillion cubic meters (227 trillion cubic feet), plus 1.7269 trillion cubic meters (61 trillion cubic feet) of crude oil associated gas reserves growth. The U.S. Interior Department estimates about growth of reserves in 1979,franklin marshall soldes, according to the calculated potential parrot 2 times the reserves data. Following the U.S. Department of Energy research, Energy Information Administration in 1990, the period of 1977-1968 increased natural gas reserves scattered comprehensive analysis. U.S. Interior Department earlier calculation of natural gas reserves increased by a factor of 3.91 (1979 data), while the Energy Information Administration calculated the coefficient of 7.72 (1986 data), almost twice the U.S. Department of Interior's , this leads to increased volume of conventional natural gas reserves of 75,021.5 cubic {B (265 trillion cubic feet), and in 1986 the Department of Energy study estimates closer. Fourth, the existing reserves of unconventional oil reservoirs in the residual is very large, about 329 million tonnes (2400 million barrels). Unconventional resources, which accounts for a considerable proportion. Than a decade, the U.S. oil industry and the Department of Energy's enhanced oil recovery in the study invested a lot of money. Tests show that in addition to thermal recovery techniques, other methods of enhanced oil recovery is not only costly but also inefficient. However, in the long run,birkenstock paris, the use of enhanced oil recovery technology to recycle the residual oil has great potential. Enhanced oil recovery method of how effective, does not seem that the efficiency of oil displacement technologies,abercrombie paris, but mainly depends on the level of awareness of complex reservoirs, and to promote the use of these technologies to complex reservoir to capacity. As of 1988, the Department of Energy studies have shown that from a technical point of view, unconventional natural gas reserves are about 7.3606 trillion cubic meters (2,2 trillion cubic feet). Since 1986, many research organizations (AAPG, the National Science and Technology, Energy Information Administration, Gas Research Institute) on the assumption that the use of advanced technology, under the conditions of estimates are 119468--142399 billion cubic meters (422--503 trillion cubic feet) with an average of 12.7395 trillion cubic meters (450 trillion cubic feet). Dense formations and geological reserves of coal seam gas were 28.31 trillion cubic meters (1,000 trillion cubic feet) and 11.324 trillion cubic meters (400 trillion cubic feet), or shale gas, natural gas, water table material, to profiling to heat resources, too. Moreover, future estimates of recoverable reserves are likely to continue to increase.
