Haynesville Shale-gas Study | Bureau of Economic Geology

Sedimentological structures include burrowing, ripples, laminations, and current laminations related to turbidites Fig. Ternary diagram showing Bossier and Haynesville mineralogical data from x-ray diffraction analyses. Production has boomed sincecreating a number of new millionaires in the Shreveport, Louisiana region. Boulder, Colorado Geological Society of America. The silt often occurs as laminations within these mudstones. The Haynesville Shale is a lithological heterogeneous, often organic-rich, mudstone.

Anderson Controls on reservoir quality and productivity in the Haynesville Shale, northwestern Gulf of Mexico Basin. The submarine fan sandstones of the Gray sand in north Louisiana are also significant producers.

The shallow coastal fodmation were bordered further north by an arid coastal plain characterized by extensive sabkhas. The calcareous particles include coccolithsbivalveand gastropod fragments, and calcispheres.

In many geological reports and journal papers, the Haynesville Shale was geolog as part of the Bossier Shale, although they are now classified as separate formations. In addition to its overall size, the Haynesville is known for its high porosities.

Jurassic basement blocks, Cretaceous thermal uplifts, and Cenozoic flexure. However, prior to that time, it was uneconomic to extract the natural gas.

J, The Gulf of Mexico Basin. Mudrocks range from calcareous-dominated facies near the carbonate platforms and islands to siliceous-dominated lithologies in areas where deltas prograded into the basin and diluted organic matter e. Geology The Upper Jurassic Kimmeridgian to Lower Tithonian Haynesville and Bossier Shales of East Texas and northwest Louisiana are currently one of the most important shale-gas formtaion in North America, having high IPs, steep decline rates, Formxtion estimated at 3 to 7 Bcf per well of each formation, and play resources estimated together in the hundreds of trillions of cubic feet.

Views Read Edit View history. Inthe Haynesville Shale was thought to be the largest natural gas field in the contiguous 48 states with an estimated trillion cubic hahnesville 7. In addition, the Gilmer Limestone member also represents a carbonate platform with oolite shoals that lie beneath central Upshur and western Smith counties, Texas.

Haynesville Shale

The goelogy by which organic matter accumulated within these sediments consisted of a complex interplay of local carbonate generation, clastic input from outside sources, variable burial rates, and variable bottom water anoxia and euxinia.

A Nation’s Hunt for an Energy Future” has been made on the subject of the mineral rights leasing “gold rush” and the potential impact of the Haynesville Shale gas play on national and global energy picture. Oil and gas is currently produced from shelf-edge carbonate reservoirs which consist of oolite shoals within the Gilmer Limestone and Buckner Anhydrite members. Porosity occurs in nano-pores as interparticle pores and within organics.

Haynesville Shale – Wikipedia

In January the formation produced 6. A third, informal member, which called the “Gray sandstone,” of the Haynesville Formation interfingers with Haynesville Shale along its northern edge.

A documentary film entitled “Haynesville: The STARR team focuses on studies of Haynesville and Bossier Shale facies, deposition, geochemistry, petrophysics, production, pore evolution, and stratigraphy in light of paleogeographic setting and regional tectonics using wireline logs, seismic, and cores.

News and Current Events.

This ancient island now lies deeply buried beneath the surface of Sabine County, Texas. As a result of rising gas filetypr and improved technology in hydraulic fracturing and directional drillingit became possible to extract the gas from the Haynesville Shale in an economic and cost-effective manner.

The Haynesville Shale is an informal, popular name for a Jurassic Period rock formation that underlies large parts of southwestern Arkansasnorthwest Louisianaand East Texas. Haynesvillee vary from calcareous mudstone near the carbonate platforms and islands to argillaceous mudstone in areas where submarine fans prograded into the basin and diluted organic matter.

More recently, as ofthe Haynesville was estimated to have 75 trillion cubic feet of recoverable gas, second only to the Marcellus Formation in the US.

Haynesville burrowed mudstone facies showing carbonate and siliceous grains, peloids, and burrows filled with calcite B. Basins colored in green; uplifts colored in red. Organic matter in the form of amorphous kerogen coats the argillaceous material. Not long after the land-leasing boom began innew mineral owners across northwest Louisiana and East Texas joined online forums and began sharing information with each other about the process of oil and gas leasing, leasing bonus payments and well production results.

The Haynesville Formation consists of marine and coastal plain limestone, shale, mudstone, and sandstone. In addition, the argillaceous matrix of such mudstones frequently contains numerous calcareous particles and stringers. Where organic filetupe is low and silts are rare, the calcareous microfossil and carbonate mud has recrystallized. Possibly, further alteration of silty, calcareous mudstones has resulted in the formation of the dolomitic mudstones and dolostones. Haunesville of Energy, Washington DC.

The carbonate platforms, their oolite shoals, the Sabine Island, and prehistoric Gulf of Formagion coastline created a restricted basin that marine currents could only readily access from the east.

As a result of these restrictive conditions, anoxic conditions frequently occurred during the deposition of the sediments that form the Haynesville Shale. Haynesville samples are from Louisiana and East Texas. Haynesville mudstones contain abundant carbonate, whereas Bossier mudstones are dominantly clay and quartz, indicating a shift from transgressive carbonate-dominated environment to progradation of clastics due to highstand deposition in the Bossier.

Reported prepared under contract no. The Haynesville Shale came into prominence in as a major producer of shale gas in East Texas and Louisiana. Texas articles missing geocoordinate data All articles needing coordinates. Cairo field, Union County, Arkansas. This natural gas is known as ” shale gas ” because the wells produce from low permeability mudstones that are also the source for the natural gas.

Northeast Marcellus Shale Utica Shale. Study area and structural controls of the Upper Jurassic northeastern Gulf of Mexico basin.
