Barnett Shale Gas is
Gas shale well productivity varies widely by basin, due to variations in the natural fracturing, richness of the shale, net thickness, and initial rates. The major change has been in well completion and operating methods, which have led to increase per well reserves.

Now they want our water, too.
Barnett Shale is deeply fractured, with fissures that tended to be sealed by calcium carbonate. The field went undiscovered until Mitchell Energy experimented with employing large gel fracture methods to open the wells to natural gas.

Faults may steal the energy from hydraulic fracturing, reducing its effectiveness, and karst features may contain abundant water that limits the production of gas. Faulting is extensive and a constant factor. For the explorationists out there, Prior noted that “Lower Hartshorne coal thickness is inversely related to thickness of the underlying Hartshorne sand.”.Research projects are underway defining CBM potential in the Desha Basin in southeastern Arkansas.
Fracture mapping demonstrates that a single fracture stage can effectively treat both the Upper and Lower Barnett. Fractures offer such a pathway. Some years ago, there was a lot of hype about another Texas play, the Austin Chalk which is a carbonate reservoir rock that has an extensive network of natural fractures .
Drilling through the shale is like drilling through a Brunswick pool table or bowling ball. Yet we find several interesting factors in the shale itself such as micro fractures that travel from the north east to the southwest. Drilling likely will shift from the standard vertical wells to more expensive horizontal wells, requiring more manpower, equipment, expertise and time. Predictions are it will take another year or so before knowing if it’s a viable commercial opportunity.
Horizontal drilling has distorted the way oil and gas drilling is done by allowing producers to drill horizontally below neighborhoods, schools and airports. Since much of the gas in the Barnett Shale is stuck under the City of Fort Worth, this new drilling expertise has fashioned a shot for the city. Horizontal Drilling is the science of drilling non-vertical wells. Directional drillers are given a well path to follow that is predetermined by engineers and geologists before the drilling starts.
Oil has also been found in lesser quantities, but sufficient (with recent high oil prices) to be commercially viable. Oil and gas investors can realize fast ROI’s. There is currently a huge Hunton Lime re-completion, de-watering play revitalization plan coming right through our back yard and we have at least 6-8 existing “cased Holes” ready for re- completion. Oil has also been found in lesser quantities, but sufficient (with recent high oil prices) to be commercially viable.
Chesapeake is continuing its drilling and leasing program in the Barnett Shale, particularly in the Core and Tier 1 area of Tarrant, Johnson, and western Dallas counties. The company’s net natural gas production in the Barnett Shale is now approximately 450 MMcfe/d. Chesapeake intervened against a new coal plant in Oklahoma, which the state turned down on Sept. Is that just self-interest or something more? Chesapeake is currently utilizing four rigs to drill Haynesville Shale wells and plans to increase its drilling activity level to approximately 10 rigs by year-end 2008 and potentially more in 2009. The company currently owns or has commitments for more than 200,000 net acres of leasehold in the Haynesville Shale and has a leasehold acquisition effort underway with the goal of owning up to 500,000 net acres in the play.
