LOCATING NIOBRARA FRACTURES-2 (CONCLUSION) ANALYZING RESISTIVITY, OIL PRODUCTION OF NIOBRARA IN WYOMING'S SILO FIELD

Sep 9, 1991 Reed A.Johnson, R. Timothy Bartshe Energy Foundation Inc. Lakewood, Colo. The Silo field area in 15n-16n/64w-65w, Laramie County, Wyo., serves as an excellent study area for Niobrara oil production in that it contains 47 vertical wells that have produced nearly exclusively from Niobrara (Fig. 7).

CANADA'S OIL, GAS RESERVES SLID IN 1990

Sep 16, 1991 Canada's conventional oil reserves and natural gas reserves declined in 1990, Canadian Petroleum Association figures show. Crude oil reserves were estimated at 4.4 billion bbl, down 6.7% from yearend 1989. Gas reserves were 71.7 tcf, down less than 1%. Oil operators replaced only a combined 27% of 1990 production. No changes occurred in established reserves in nonproducing frontier fields.

PORTFOLIO MANAGEMENT STRATEGY OFFERED FOR PRODUCING PROPERTIES

Oct 7, 1991 David A.B. Brown The Windsor Group Inc. Boston Domestic independents are too often the forgotten participants of the U.S. exploration and production industry. As a group, they are diverse in character and culture and differ greatly from the more visible integrated domestic and international producers. Independents are frequently companies of scale, with the 30 largest accounting for $7.5 billion in annual revenues. They often lack the more formalized financial, planning, and control systems

ENRON SEES MAJOR INCREASES IN U.S. GAS SUPPLY, DEMAND

Oct 7, 1991 Margaret M. Carson, Bruce Stram Enron Corp. Houston Enron Corp., Houston, in an extensive study of U.S. natural-gas supply and demand through the year 2000, has found that the U.S. gas-resource base is 1,200 tcf. Despite current weaknesses in natural-gas prices, demand growth will be strong although affected by oil-price assumptions. Highlights in the areas of reserves and production include gains in both categories in the Rockies/Wyoming, San Juan basin, and Norphlet trends (offshore Alabama).

U.S. TAX CREDITS SPURRING COAL SEAM, TIGHT SANDS BOOM AMID CONTROVERSY

Oct 14, 1991 A.D. Koen Gulf Coast News Editor Federal tax credits have sparked a boom in U.S. drilling for gas contained in coal seams and tight sands. Some analysts say drilling for unconventional nonassociated gas accounted for as much as one third of all U.S. gas wells drilled in 1990. Production of unconventional gas is leaping, and this source is providing the biggest share of net gas reserves growth in the U.S. With the recent expansion of federal tax credits beyond coal seam gas to include tight

U.S. BRIEFS

Oct 28, 1991 UNOCAL CORP. made the final $8.2 million payment to the California State Lands Commission in settlement of two multimillion dollar antitrust lawsuits alleging price fixing in the early 1970s and early 1980s by seven major oil companies (OGJ, Aug. 26, p. 71). The Unocal payment is part of a $77 million settlement package agreed to in January.

COMMENT ENSERCH CORP.'S BIEGLER: HOW TO DIAGNOSE U.S. GAS INDUSTRY'S ILLS

Oct 28, 1991 David W. Biegler President Enserch Corp. Dallas Adapted from an Oct. 1 speech to a Natural Gas Week conference in Houston. More and more, people are seeking some understanding of just what is happening in the U.S. natural gas industry. I have attempted to put a framework around today's natural gas industry in the form of a dozen "laws" that provide some insight. The future's not what it used to be.

WYOMING WINTER DRILLING PROGRAM BEARS FRUIT

Jan 13, 1992 Celsius Energy Co., Salt Lake City, has completed an Upper Cretaceous Almond (Mesaverde) gas discovery on the Mulligan Draw federal exploratory unit in the Washakie basin. The 4 Mulligan Draw Unit, in 33-16n-95w, Sweetwater County, 25 miles south-southwest of Wamsutter, flowed at the rate of 400 Mcfd of gas from the zone at about 12,800 ft. A frac job is scheduled for early this year. The company is evaluating preliminary results of the discovery, which could significantly extend the size of

COMMENT U.S. GAS PRODUCERS HAVE LITTLE CHOICE BUT TO SELL

Jan 13, 1992 Vinod K. Dar Dar & Co. Washington The first days of January bode ill for February U.S. natural gas prices. The winter continues, at best, to be seasonal. Storage has gone from a small cloud on the horizon to a grey pall across the natural gas landscape. Industrial gas demand remains weak because of a pedestrian economy. Tax induced deliverability continues to expand vigorously. Consequently, the price for Gulf Coast gas could dip below $1.30/MMBTU in February, which would be the lowest

EFFECTS OF DIFFERENTIAL COMPACTION FRACTURING SHOWN IN FOUR RESERVOIRS

Feb 3, 1992 Gilbert E. Thomas Thomas & Associates Denver With the advent of horizontal drilling in the U.S., fractured reservoirs have become a major target in the ongoing search for hydrocarbons. Early optimism resulting from the high initial production rates for horizontal wells, however, is now being replaced by a more realistic view as many such wells are exhibiting rapid declines in production. This is especially true for the Mississippian Bakken shale play in the Williston basin and the Cretaceous

DOE PROPOSES BIG HIKE IN R&D ON NATURAL GAS

Feb 3, 1992 The U.S. Department Energy proposes to more than triple its gas research spending in its fiscal 1993 budget request. Energy Sec. James Watkins said, "We have not done the job in gas research and development. "We hope this will help get gas demand up." Gas R&D, budgeted at $12.54 million last fiscal year, is targeted for $40 million. The program will focus on industry and market needs using a "systems approach" to try to solve problems in supply, delivery, storage, and utilization. It will

Mar 23, 1992 Alberta oilsands continue to attract companies aiming for a breakthrough in economic development of the resource. Chevron Canada Resources Co. has started up a pilot oilsands project northeast of Edmonton using its heated annulus steam drive (HASDrive) process. In addition, Fording Coal Ltd., Calgary, and Kilborn Western Inc. plan a joint venture to develop a new oilsands extraction process. Chevron's $12 million (Canadian) pilot oilsands project in Alberta employs its HASDrive process,

FRACTURED ZONES DRAW HORIZONTAL TECHNOLOGY TO MARIETTA BASIN

Mar 30, 1992 M.G. Whitmire Bandera Petroleum Inc. Tulsa Vertically fractured, low permeability reservoirs have long frustrated the efforts of oil and gas operators. Oil men, risk takers by nature, cannot resist the challenge to try to beat the average, subeconomic well and get the better wells. The advent of horizontal drilling technology gave new life to these hopes, and a number of drilling mini-booms developed in a diverse, widespread variety of vertically fractured U.S. reservoirs. Results to date have

REFINERS DISCUSS HF ALKYLATION PROCESS AND ISSUES

Apr 6, 1992 Safety and oxygenate operations made HF alkylation a hot topic of discussion at the most recent National Petroleum Refiners Association annual question and answer session on refining and petrochemical technology. The panel of experts responded to a variety of questions regarding the mechanical, process, and safety aspects of the HF alkylation process. Among the issues discussed were mitigation techniques, removal of oxygenates from alkylation unit feed, and amylene alkylation.

BIG U.S. GAS PRODUCING STATES FAN PRORATIONING CONTROVERSY

May 4, 1992 The biggest gas producing states in the U.S. are embracing wholesale changes in prorationing rules. And their actions have stirred controversy and warnings among key energy lawmakers in Washington. The Texas Railroad Commission last week unanimously approved new rules for setting production volumes for gas wells. Texas is the country's No. 1 gas producer. TRC commissioners eliminated a system that prorated production based on monthly nominations by gas purchasers. But they left the door
