SEG’s May survey of oil companies and domestic seismic contractors indicated a seasonal increase in seismic exploration activity during the month — the first reversal of the downtrend which began in September 1975. SEG’s count of seismic crews active in the U.S. and U.S. waters during May is 247, up nine crews from the 238 reported in April. This increase compares with a three‐crew increase during the same two months in 1975 (283 to 286).

SEG’s Seismic Crew Survey for July 1976 shows an increase of 12 land crews and marine vessels engaged in exploration for oil and gas in the U.S. and U.S. waters, including Alaska. The information shown in Table 1 is compiled from data reported by oil companies operating company‐owned seismic exploration crews and vessels by contract seismic exploration companies.

SEG’s Seismic Crew Survey for September 1975 shows a total of 274 land crews and marine vessels engaged in exploration for oil and gas in the U.S. and U.S. waters, including Alaska. The information shown in Table 1 is compiled from data reported by oil companies operating company‐owned seismic exploration crews and vessels and by contract seismic exploration companies.

SEG’s November 1975 count of seismic crews active in the U.S. and U.S. waters, including Alaska, shows a decline for the third straight month and a continuation of the downward slide in seismic exploration activity which began in July 1974. The total crew figure for November 1975 is 265, down five crews from the previous month. This reflects a net decline of three land and two marine crews.

Summary A casual reading of the SPE/WPC (World Petroleum Congresses) Petroleum Reserves Definitions (1997) and the U.S. Securities and Exchange Commission(SEC) definitions (1978) would suggest very little, if any, difference in the quantities of proved hydrocarbon reserves estimated under those two classification systems. The differences in many circumstances for both volumetric and performance-based estimates may be small. In 1999, the SEC began to increase its review process, seeking greater understanding and compliance with its oil and gas reserves reporting requirements. The agency's definitions had been promulgated in 1978 in connection with the Energy Policy and Conservation Act of 1975 and at a time when most publicly owned oil and gas companies and their reserves were located in the United States. Oil and gas prices were relatively stable, and virtually all natural gas was marketed through long-term contracts at fixed or determinable prices. Development drilling was subject to well-spacing regulations as established through field rules set by state agencies. Reservoir-evaluation technology has advanced far beyond that used in 1978;production-sharing contracts were uncommon then, and probabilistic reserves assessment was not widely recognized or appreciated in the U.S. These changes in industry practice plus many other considerations have created problems in adapting the 1978 vintage definitions to the technical and commercial realities of the 21st century. This paper presents several real-world examples of how the SEC engineering staff has updated its approach to reserves assessment as well as numerous remaining unresolved areas of concern. These remaining issues are important, can lead to significant differences in reported quantities and values, and may result in questions about the "full disclosure" obligations to the SEC. Introduction For virtually all oil and gas producers, their company assets are the hydrocarbon reserves that they own through various forms of mineral interests, licensing agreements, or other contracts and that produce revenues from production and sale. Reserves are almost always reported as static quantities as of a specific date and classified into one or more categories to describe the uncertainty and production status associated with each category. The economic value of these reserves is a direct function of how the quantities are to be produced and sold over the physical or contract lives of the properties. Reserves owned by private and publicly owned companies are always assumed to be those quantities of oil and gas that can be produced and sold at a profit under assumed future prices and costs. Reserves under the control of state-owned or national oil companies may reflect quantities that exceed those deemed profitable under the commercial terms typically imposed on private or publicly owned companies.

Three‐dimensional (3-D) seismic prospecting is generally perceived as a very expensive tool that is not suitable for use by other than major oil companies or for the solution of conventional exploration geophysics problems. We illustrate how 3-D techniques were used to provide a very cost‐effective solution to a specific exploration project. A basic geologic and historical seismic outline establishes the economic and environmental framework for the survey. Drilling results and comparisons with conventional data illustrate the effectiveness of the 3-D approach. This survey was carried out during February of 1982 in the Black Creek basin of northwestern Alberta. Prolific and abundant Devonian Keg River pinnacle reefs with reserves in the 0.2 to 100 million barrel recoverable categories provide the exploration target. A prospective area of approximately [Formula: see text] was covered with a 165 ft subsurface grid of 1200 percent CDP data. Field data were acquired with a conventional 96-trace dynamite crew using a rolling, crossed‐array technique. Data processing was carried out with a flexible, conventional seismic processing package, including wavelet deconvolution, surface‐consistent statics, 3-D migration, and geologic slice displays. Total cost of the survey was $50,000 Canadian per sq mi. This paper demonstrates the interpretive power of 3-D surveys.

On March 7, 1995, Conoco oil company of Houston, Texas, announced that it had entered into a contract with Iran to have a Netherlands-based affiliate assist in the development of the Sirri Island oil field. In response, the Clinton administration issued Executive Order No. 12,957, prohibiting participation by U.S. entities in the development of Iranian petroleum resources. Eventually, Conoco withdrew from its contract, but in early May of 1995 the administration stepped up its pressure on Iran by issuing Executive Order No. 12,959, prohibiting U.S. entities from using foreign entities they owned or controlled to make investments in or conduct trade transactions with Iran. On July 13 of that year, the French oil company Total S.A. entered into an agreement with Iran to replace Conoco in developing the Sirri Island field, and over the next several months Iran struck nearly a dozen petroleum development agreements worth in excess of $50 million each with other foreign oil companies. Within a couple of months, both Houses of the U.S. Congress took up consideration of proposals to complicate Iran’s ability to develop its hydrocarbon resources. By the end of 1995, the proposals, which even extended to wholly foreign entities organized and operating outside the United States, had come to include Libya as well. Final passage of one of the proposals, specifically, H.R. 3107, took place in the Senate and the House in July 1996. It was signed into law as the Iran and Libya Sanctions Act (ILSA) on August 5.

After four straight months of increased activity, SEG’s September survey of oil companies and domestic contractors shows exploration in the U.S. and U.S. waters declined during the month (Figure 1). Comparative figures for U.S. land crews and marine vessels are given in Table 1. Preliminary seismic crew data from outside the U.S. were reported for the first time in September. The information in Table 2 was reported by the oil companies and contractors who provided the U.S. data. Additional data from other companies being surveyed will be announced as soon as it is available. SEG’s U.S. Seismic Crew Count is taken monthly for the Federal Energy Administration and is financed by a grant from the International Association of Geophysical Contractors.

After two months of slightly decreased activity, SEG’s November survey of oil companies and domestic contractors shows exploration in the U.S. and U.S. waters increased during the month (Figure 1). Comparative figures of U.S. land crews and marine vessels are given in Table 1. Seismic crew data from outside the U.S. (shown in Table 2) were reported by the oil companies and contractors who provided the U.S. data.
