Barnett Shale

Barnett Shale Description Image

The Barnett shale in north-central Texas lies in the Fort Worth Basin. Discovered in the 1950s, the Barnett was not commercially viable until the 1980s. Some geologists believe the formation could hold 30 trillion cubic feet of natural gas. A significant part of the drilling has occurred in the Fort Worth metro area, and Chesapeake Energy actually secured rights to drill beneath the Dallas-Fort Worth International Airport.

Drilling in the Barnett shale intensified in the past decade as modern horizontal drilling and hydraulic fracturing techniques were perfected for drilling in shale. Devon Energy, Chesapeake Energy, XTO Energy, and EOG Resources are among the larger players in the Barnett shale. Two years ago, 70% of all US gas shale production came from the Barnett, but that percentage of the total has been declining as production has risen in other plays.

Mitchell hikes Barnett shale reserves, Fort Worth basin output in N. Texas

Sep 27, 1999 Mitchell Energy & Development Corp., The Woodlands, Tex., is quickening recompletion and drilling programs aimed at gas in low permeability Mississippian Barnett shale in the Fort Worth basin in North Texas.

Area Drilling

Jun 21, 1999 Red Sea Oil Corp. and Lundin Oil AB plan to start production from En Naga North and West fields on NC 177 in the southern Sirte basin within 12 months after approval of a development plan. The firms filed the plan with a management committee controlled by Libyan National Oil Co. Peak production is estimated at 22,000 b/d 24 months after start-up (OGJ, Dec. 14, 1998, p. 88). The firms will continue exploring the block using $43.6 million (Canadian) raised in a rights offering, with C1-NC 177 to

Use resistivity as indicator of source rock maturity

May 10, 1999 The resistivity of various shale source rocks has been observed to increase with depth (Bakken, Barnett, Mowry, Niobrara, Woodford, etc.). This relationship can be explained by the retention of generated hydrocarbons in micropores. The generalized process requires: 1) a volume increase during conversion of kerogen to fluid hydrocarbons; 2) a rigid framework that provides a fixed volume of available pore space, and 3) micropores with micropermeability that retain hydrocarbon globules through

Fort Worth basin operator to add Barnett shale infill wells, reserves

Jan 4, 1999 An independent producer plans to develop more gas in Mississippian-Devonian Barnett shale in the Fort Worth basin. The Texas Railroad Commission approved field rule amendments that will allow increased well density in the formation. Mitchell Energy & Development Corp. said the rules permit it to drill wells in Newark East field on as little as 40 acre spacing. Mitchell expects that as many as 100 wells with a combined 80 bcf of estimated net gas reserves will be added to the proved undeveloped

In the group for which bids close in March 1998: The Browse basin, which has supergiant gas reserves and now the major Cornea oil discovery, has the potential for more major discoveries in moderate to deep water between the petroleum kitchens and basin margin fields; Elsewhere, shallow water, underexplored parts of the oil productive Bonaparte basin

Mitchell to hike gas production in North Texas

Oct 2, 1995 Mitchell Energy & Development Corp., The Woodlands, Tex., plans to boost its North Texas gas production by 25-30 MMcfd during the next 12 months from 100 MMcfd earlier this year. Its program involves placing spare productive capacity on line, stepping up the pace of well completions, increasing deliverability in gathering systems, and serving more gas markets in the area. The program stems from Mitchell's buyout last July of a premium priced gas sales contract with Natural Gas Pipeline Co.

One of these areas is the Petrel sub-basin of the Bonaparte


Jul 11, 1994 With David Knott from London Refiners in a number of European countries can't meet prevailing patterns of demand. There is excess capacity for some products, while others are in short supply. A report published by FT Business Information Ltd., London, says shifting demand patterns will worsen the imbalance for many refiners. The remedy is a familiar one: "Considerable investment is necessary. The general shift in European demand is toward lighter petroleum products. This and tighter
