Other Unconventional Oil

Other Unconventional Description ImageIn addition to the well-known gas shale plays like the Barnett, Haynesville, Marcellus, and Eagle Ford, and oil plays like the Bakken, there are perhaps dozens of smaller, less well-known resource plays, many of which are in the very early stages of exploration and development. Some of the plays are shale and others are tight gas or coalbed methane. Many are in the United States and Canada, but increasingly exploration and production companies are using modern drilling and production technology to develop natural gas and oil from unconventional subsurface formations in Europe and Asia. Doubtless, unconventional resources eventually will be exploited in Africa, South America, and Australia as well. What we call “unconventional” today will be considered “conventional” in time.

Jul 4, 1994 WESTERN GAS RESOURCES INC. unit Western Gas Resources Storage Inc., Denver, New York Mercantile Exchange, and Enersoft Corp., Richardson, Tex., propose to provide for electronic trading of gas at Western's Southeast Texas Katy hub and gas storage site. Trades are expected to be made via the Channel 4 on-line trading and information management system.


Jul 25, 1994 G. Alan Petzet Exploration Editor Robert J. Beck Economics Editor Drilling in the U.S. will pick up slightly during second half 1994, but the first half to second half increase proportionally will not be as large as in Canada. Operators appear likely to drill nearly half as many wells this year in western Canada as they will drill in the U.S.

Feb 27, 1995 Edward D. Minihan , Ray D. Buzzard Consulting petroleum geologists Fort Worth The New Albany shale of southwestern Indiana is a worthwhile exploration and exploitation objective. The technical ability to enhance natural fractures is available, the drilling depths are shallow, long term gas reserves are attractive, markets are available, drilling costs are reasonable, risks are very low, multiple drilling objectives are available, and the return on investment is good. Indiana Geological Survey


Mar 6, 1995 G. Alan Petzet Exploration Editor Land and state waters of the U.S. contain technically recoverable volumes of 112.6 billion bbl of oil and 1,073.8 tcf of conventional and unconventional gas, the U.S. Geological Survey estimated. The figures include proved reserves, expected future additions to reserves in existing fields, and undiscovered resources (Table 1) (31684 bytes) . Donald L. Gautier of Denver, project chief for the USGS study, called the volumes "astonishing."


Mar 13, 1995 Much oil and gas remains to be discovered and produced in the U.S. The U.S.? Isn't that the world's most mature producing region, considered by conventional wisdom to be all but drilled up? Yes, the U.S. According to a new study by the U.S. Geological Survey, the mature, drilled-up U.S. has technically recoverable volumes of 113 billion bbl of oil and 1.1 quadrillion cu ft of natural gas (OGJ, Mar. 6, p. 84). In these terms, the country has six times the oil and eight times the gas


Apr 10, 1995 AN ANCHORAGE superior court judge ruled Exxon Corp. does not have pay anything to Alaskan native corporations to compensate for damage to native and public lands as a result of the Mar. 24, 1989, Exxon Valdez tanker spill off Alaska. That followed a jury verdict 6 months ago calling for Exxon to pay the plaintiffs $9.7 million in damages. The judge, who presided over that trial, said the native corporations were more than compensated through a federal liability fund and a previous legal


Jun 5, 1995 Gerry G. Calhoun Consulting petroleum geologist Midland, Tex. The recent surge of activity involving self-sourcing reservoirs and horizontal drilling recognizes a little tapped niche in the domestic energy mix. Such prolific pays as the Cretaceous Bakken and Austin Chalk have drawn research interest and large amounts of investment capital. Fluorescence analysis can discern movable oil-as opposed to exhausted source rock-in such reservoirs with an inexpensive test.


Jul 31, 1995 G. Alan Petzet Exploration Editor Robert J. Beck Associate Managing Editor-Economics U.S. drilling in the second half of 1995 will pick up from the low first-half level, pushing the total number of wells drilled during the year to about the level of 1994. Drilling is easing in Canada from the binge of 1994, but it is still above 1992-93 levels. Here are highlights of OGJ's midyear U.S. drilling forecast for 1995 (43926 bytes): Operators will drill 21,900 wells, compared with the 21,950

ENERGY MINERALS Oil shale, coalbed gas, geothermal trends sized up

Sep 11, 1995 G. Warfield Hobbs Ammonite Resources Co. New Canaan, Conn. The first part of this article discussed demographic and consumption trends in energy resource utilization, and the second part reviewed developments in conventional petroleum, uranium, and tar sands. In this third and final section, oil shale, coalbed methane, and geothermal resources with be covered together with energy fuel reserve life and the study's conclusions regarding the future of energy minerals.


Sep 11, 1995 Pine Needle LNG Co. intends to add Public Service Co. of North Carolina Inc. and North Carolina Natural Gas Corp. to the limited liability company formed by units of Transcontinental Gas Pipe Line Corp. and Piedmont Natural Gas Co. Inc. The company plans to seek approval from the Federal Energy Regulatory Commission to build, own, and operate a $107 million liquefied natural gas peak demand plant in North Carolina (OGJ, June 12, p. 44).

Technology spurs growth of U.S. coalbed methane

Jan 1, 1996 Scott H. Stevens, Jason A. Kuuskraa Advanced Resources International Inc. Arlington, Va. Richard A. Schraufnagel Gas Research Institute Chicago Since the late 1980s, more than $2 billion in capital investments and continued technological advances have harnessed an entirely new source of natural gascoalbed methane (CBM). From its roots as an experimental coal mine degasification method, the CBM industry today has grown into a significant component of U.S. natural gas supply.

EXPLORATION New basins invigorate U.S. gas shales play

Jan 22, 1996 Scott R. Reeves Vello A. Kuuskraa Advanced Resources International Inc. Arlington, Va. David G. Hill Gas Research Institute Chicago While actually the first and oldest of unconventional gas plays, gas shales have lagged the other main unconventional gas resources-tight gas and coabed methane-in production and proved reserves. Recently, however, with active drilling of the Antrim shales in Michigan and promising results from the Barnett shales of North Texas, this gas play is growing in

Slight Rise Possible In U.S. Drilling; Canadian Action Sags

Jan 29, 1996 G. Alan Petzet Exploration Editor Robert J. Beck Associate Managing Editor-Economics The low level of U.S. drilling evident in 1995 is likely to continue into 1996. Anticipated increases in the average prices of crude oil and natural gas will sustain only about a 2% increase in the number of wells drilled year to year in the U.S. A second year of decline can be expected in Canada from 1993's historic high, but total drilling will remain above the average of well counts for the past 10
