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.

API: '95 U.S. drilling outlays up 8.9%

Nov 25, 1996 Oil industry expenditures to drill and equip oil and gas wells in the U.S. rose 8.9% to $10.5 billion in 1995, American Petroleum Institute reported. The 1995 Joint Association Survey found U.S. operators drilled 20,528 wells, up 2.5% from 1994. Total footage was 120,834,000, and average cost per well was $513,415, or $87.22/ft. Oil wells were up 18.8% at 7,745, gas wells fell 7.1% to 7,863, and dry holes slipped 2.3% to 4,920.

Michigan to get horizontal and directional well projects

Aug 11, 1997 Operators have planned several noteworthy horizontal and directional projects in Michigan. Recent drilling has identified a substantial gas/condensate accumulation in Ordovician Prairie du Chien at the head of Saginaw Bay. Michigan's longest offset directional well is being drilled with a 7,200 ft displacement to tap a portion of the field beneath the bay.

World resource statistics geared for electronic access

Oct 13, 1997 This article describes the first public presentation, by basin, of quantitative, worldwide conventional petroleum resource assessments. These assessments are presented in tabular form along with a world petroleum basin map keyed to the tables. The assessments are now available on a U.S. Geological Survey web site, http://energy.er.usgs.gov/products/papers/world_oil/index.htm .

Where future Canadian gas supply will originate

Dec 15, 1997 Natural gas from Canada is becoming an increasingly important component in the North American gas market. Future supplies of natural gas from Canada will come, first, from the Western Canada sedimentary basin and southern Ontario and Quebec ( Fig. 1 [121,867 bytes] , Category A), where all current gas production is obtained and where the producing infrastructure is in place. Secondly, gas will come from the frontier basins in Canada, where gas discoveries have been made but where neither

Canadian gas hunt to target small pools

Nov 16, 1998 Future natural gas exploration in Canada will involve numerous small-pool discoveries and new strategies for companies, says the Canadian Gas Potential Committee (CGPC). CGPC spokesman Richard Proctor says that Canadian operators will have to drill substantially more wells every year to meet increasing demand for Canadian gas in the expanding North American market. CGPC is an independent committee of geologists and engineers affiliated with the University of Calgary.

US crude reserves plunged 7% in 1998

Jan 3, 2000 The US Energy Information Administration reports proved reserves of US crude oil fell 7% in 1998, the largest percentage decline in over 50 years. Crude reserves were 21.03 billion bbl, down 1.5 billion from the end of 1997.

Partnership targets unconventional gas reserves

Jun 18, 2001 Gas Technology Institute, Des Plaines, Ill., and one of its long-time contractors set up a commercial partnership to offer unique methods to reduce risks of developing gas in over and underpressured formations.

OGJ Newsletter

Apr 22, 2002 Despite Iraq's Apr. 8 announcement of a 30-day suspension of oil exports and turmoil at Petroleos de Venezuela SA in Venezuela, the oil market has responded in a muted fashion, according to the International Energy Agency, because such events were already incorporated into a "geopolitical risk premium."

EnCana pursues Northeast BC Devonian reef margin play

Jun 24, 2002 One of Canada's largest oil and gas companies is pursuing unconventional gas opportunities in Northeast British Columbia in what it calls the largest regional gas play discovered in western Canada in the last decade.

Future gulf supplies: Role of the federal government

Sep 2, 2002 The US Gulf of Mexico (GOM), providing 1.8 million b/d of crude oil/NGLs and 14 bcfd of natural gas, has been a major source of domestic energy supplies. However, considerable uncertainty surrounds the outlook for this critical oil and gas producing area, with many concluding that production is or soon will be in decline.
