In addition, the Gilmer Limestone member also represents a carbonate platform with oolite shoals that lie beneath central Upshur and western Smith counties, Texas. However, prior to that time, it was uneconomic to extract the natural gas. It was known to contain large quantities of natural gas prior to 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 plays in North Filefype, having high IPs, steep decline rates, EURs estimated at 3 to 7 Bcf per well of each formation, and play resources estimated together in the hundreds of trillions of cubic feet Fig.
Where organic matter is haynesvikle and silts are rare, the calcareous microfossil and carbonate mud has recrystallized. Production haynesvillle boomed sincecreating a number of new millionaires in the Shreveport, Louisiana region. Views Read Edit View history. Hettangian Sinemurian Pliensbachian Toarcian. The STARR team focuses on studies of Haynesville and Bossier Shale facies, deposition, geochemistry, petrophysics, production, pore evolution, filetupe stratigraphy in light of paleogeographic setting and regional tectonics using wireline logs, seismic, and cores.
Department of Energy, Washington DC. The composition of these mudstones varies greatly depending on position on geographic location and stratigraphic position.
The mudstone comprising it accumulated as a widespread and laterally continuous blanket across the fkletype of this restricted basin.
Sedimentological structures include burrowing, ripples, laminations, and current laminations related to turbidites Fig. The Haynesville Shale is fofmation informal, popular name for a Jurassic Period rock formation that underlies large parts of southwestern Arkansasnorthwest Louisianaand East Texas.
Haynesville Shale Overview – Maps – Geology – Counties
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 silt often occurs as laminations within these mudstones. 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. Gulf Coast Association of Geological Societies.
Retrieved from ” https: In that well, the Haynesville Shale consists of silty, argillaceous mudstones, silty, calcareous mudstones, and dolomitic mudstones and dolostones. In these mudstones, the calcite occurs as silt-sized microfossil hash composed of fragmented fossils tormation carbonate mud. Bioturbated calcareous mudstone showing abundant calcitic bioclasts in organic-rich matrix.
The other members of the Haynesville Formation are also the source of oil and gas production. The Haynesville Shale underlies an area of about 9, square miles and averages about to ciletype thick. The submarine fan sandstones of the Gray sand in north Louisiana are also significant producers.
Organic matter in the form of amorphous kerogen coats the argillaceous material. The Haynesville Shale was deposited in a restricted basin that was located on a southward sloping continental shelf covered by relatively shallow water.
Study area and structural controls of the Upper Jurassic northeastern Gulf of Mexico basin. The southern rim of this ancient basin and extent of the Haynesville Shale was an ancient Jurassic island, called “Sabine Island. This ancient island now lies deeply buried beneath the surface of Sabine County, Texas.
Very limited detailed descriptions of the Haynesville Shale indicated that it is fossiliferous.
Haynesville Shale – Wikipedia
In January the formation produced 6. This sandstone is regarded as having accumulated as submarine fans carrying sediment from the coastline into the basin within which the Haynesville Shale accumulated.
The New York Times.
They comprise the western boundary of the ancient shelf basin within which Haynesville Shale accumulated. From Wikipedia, the free encyclopedia. Porosity occurs in nano-pores as interparticle pores and within organics.
Basins colored in green; uplifts colored in red. The reported fossils include unidentified coccoliths, bivalves, gastropods, and calcispheres. Both stratigraphic relationships and a nannofossil coccolith assemblage described from it indicates that it is Kimmeridgianto million years old, in age. Jurassic basement blocks, Cretaceous thermal uplifts, and Cenozoic flexure.
The Haynesvjlle Jurassic Kimmeridgian to Lower Tithonian Haynesville and Bossier Shales of East Texas and northwest Louisiana are currently one of the most important shale-gas plays in North America, having high IPs, steep decline rates, EURs estimated at 3 to 7 Bcf per well of each formation, and play resources estimated together in the hundreds of trillions of cubic feet.
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.
