Piceance/Uinta Tight Gas

Piceance/Uinta Description ImageThe Piceance and Uinta basins are in northeastern Utah and northwestern Colorado. Both the Piceance and Uinta are tight gas resources plays. The primary target of gas development has been the Williams Fork formation, of Cretaceous age, in the Mesaverde group. The Williams Fork is a several-thousand-foot thick section of shale, sandstone, and coal deposited in a coastal plain environment. The formation has long been known to contain natural gas. However, the sandstone reservoirs have low permeability and limited areal extent, which made gas wells uneconomic in the past.

Key players in the Piceance and Uinta resource plays include Chevron, Encana, ExxonMobil, Noble Energy, Bill Barrett Corp., Antero Resources, Delta Petroleum, Laramie Energy, and Harvest Natural Resources – to name just a few.

More data point to potential in S. Colorado sub-basin

Sep 1, 1997 Lexam Explorations (U.S.A.) Inc. encountered strong shows of oil in 27 of 42 shallow gold exploration wells it drilled in 1992-93 along the west flank of the Sangre de Cristo mountains in south central Colorado. This also happens to be the east flank of the Tertiary San Luis basin, an area that conventional wisdom rejected for oil exploration due to the erroneous interpretation that all of the Paleozoic and Mesozoic sections were eroded away during the Lara- mide.


Nov 11, 1996 U.S. Energy Department approved sale of another 1.9 million bbl of oil from the Strategic Petroleum Reserve for $39.5 million (OGJ, Nov. 4, p. 38). Successful bidders for crude from the West Hackberry site near Lake Charles, La., were Texaco Trading, which bought one batch of 200,000 bbl for $20.82/bbl and another for $20.57/bbl, and Coastal States Trading, which bought 900,000 bbl for $20.95/bbl and 600,000 bbl for $20.70/bbl. Huntsman Corp.,


May 13, 1996 Williams Field Services Corp., a unit of Williams Cos. Inc., Tulsa, started commercial operations at its 62,000 kw cogeneration plant, built alongside its Milagro gas treating plant near Farmington, N.M. It produces about 300,000 lb/hr of steam used to remove CO2 at the Milagro plant. Power is sold to Louis Dreyfus Electric Power Inc. under a long term contract.

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.

NEWS Technical skills bolster success rate for U.S. independent operators

Sep 18, 1995 A.D. Koen Senior Editor-News Independent oil and gas producers are applying new technical skills to achieve hefty rates of U.S. exploration success. Operators report strong showings in exploration despite or perhaps because of economic challenges. Lackluster wellhead prices in the U.S. continue to squeeze upstream economics, discouraging drilling of any kind. U.S. producers, meantime, continue to lose ground on domestic crude oil markets, while competition intensifies on U.S. gas markets.


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.


Mar 13, 1995 U.S. COAST GUARD issued a final rule covering double hull oil tankers under the Oil Pollution Act of 1990 (OPA). The rule sets minimum requirements for space between the two hulls for all vessels trading in U.S. waters. OPA also establishes a phaseout schedule that began Jan. 1 for existing single hull vessels. By 2015, all oil tankers trading in U.S. waters must be double hulled.


Mar 6, 1995 Charles Willis River Gas Corp. Northport, Ala. An efficient system of drilling core holes for data followed by drilling, tracing, and producing gas wells helped develop economic quantities of coalbed methane. The objective of the Drunkards Wash, Utah, project is to explore for and produce commercial quantities of methane from medium-depth coal seams in east central Utah. Current gas production rates are exceeding the projections made prior to development and used for initial economic


Dec 19, 1994 NOVAGAS CLEARINGHOUSE LTD., Calgary, plans to build a 40 MMcfd gas processing plant and associated gathering pipelines at Zama Lake, Alta., 700 km northwest of Edmonton. The $30 million (Canadian) plant will be built next to a gas processing plant operated by Pennzoil Canada Inc., which will operate the Novagas plant under contract. MOBIL CHEMICAL CO. is expanding capacity to produce base stocks for synthetic lubricants to 10 million gal/year from 7 million gal/year at its Beaumont, Tex.,


Dec 12, 1994 NIGERIA LNG LTD. and a group including M.W. Kellogg Co., Technip SA, Snamprogetti SpA, and JGC Corp. signed a memorandum of understanding for construction of a $4.5 billion, 5.9 million metric ton/year liquefied natural gas export complex at Bonny Island in Rivers state, Nigeria. Construction is to start next year, with first exports slated for first half 1999. The project team will consist of members from each company and will be based in M.W. Kellogg's London office.


Aug 8, 1994 Department of Energy specialists at Bartlesville, Okla., have begun evaluating 31 proposals submitted by oil producers, universities, and others in DOE's cost shared round of projects involving U.S. slope and basin clastic reservoirs. Selections are to be announced in September. Copies of complete public abstracts submitted by the proposers are available from the communications office of DOE's Office of Fossil Energy in Washington, D.C. Synopses of the Class III mid-term projects were


Jun 20, 1994 A FEDERAL JURY in Anchorage found Exxon Corp. and former Exxon Valdez tanker Capt. Joseph Hazelwood acted recklessly in the 1989 oil spill off Alaska. That opened the door for more than 10,000 plaintiffs to pursue $15 billion in potential punitive damages related to the spill. The trial's next phase, to begin next month, will assess the amount of punitive damages. Exxon contends no punitive damages should be awarded because it has spent more than $3 billion in cleanup and settlement


May 16, 1994 Robert T. Fabian Hycalog Houston A rock strength analysis program, through intensive log analysis, can quantify rock hardness in terms of confined compressive strength to identify intervals suited for drilling with polycrystalline diamond compact (PDC) bits. Additionally, knowing the confined compressive strength helps determine the optimum PDC bit for the intervals.


Mar 28, 1994 GENERAL MOTORS CORP. asked owners of its 2,500 natural gas powered pickup trucks to take the vehicles off U.S. roads while it investigates fuel tank explosions that injured two persons. Both explosions occurred during fueling. GM is lending owners new trucks or reimbursing them for the cost of leasing replacements.


Feb 14, 1994 PHILIPPINE NATIONAL OIL CO. (PNOC) will begin developing a site for the Philippines' first petrochemical complex $300 million project proposed by a group led by industrialist John Gokongwei (OGJ, Oct. 25, 1993, p. 38). PNOC is negotiating with Gokongwei's JG Summit Holdings Corp., Mitsui Engineering & Shipbuilding Corp., and an undisclosed third company to build a 160,000 metric ton/year, $129.6 million polypropylene plant.
