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.

W. CANADA BOOM TO OUTSHINE SECOND HALF U.S. DRILLING RISE

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.

MODERN DEVONIAN SHALE GAS SEARCH STARTING IN SOUTHWESTERN INDIANA

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.

PARTIAL U.S. OIL, GAS RESOURCE VOLUMES TERMED 'ASTONISHING'

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."

U.S. STILL HAS OIL, GAS ALLURE

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

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

FLUORESCENCE ANALYSIS CAN IDENTIFY MOVABLE OIL IN SELF-SOURCING RESERVOIRS

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.

U.S. DRILLING DUE SECOND-HALF REBOUND; CANADA'S BINGE COOLS

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

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
