The silt ffiletype occurs as laminations within these mudstones. For example, the Haynesville Shale has been observed to vary in composition from 25 to 35 percent clay and 5 to 30 percent calcite in samples recovered from one filehype and gas well.
In addition, the Gilmer Limestone member also represents a carbonate platform with oolite shoals that lie beneath central Upshur and western Smith counties, Texas. Views Read Edit View history. J, The Gulf of Mexico Basin.
Department of Energy, Washington DC. Hettangian Sinemurian Pliensbachian Toarcian. This sandstone is regarded as having accumulated as submarine fans carrying sediment from the coastline into the basin within which the Haynesville Shale accumulated. Both the silty, argillaceous mudstones and silty, hhaynesville mudstones often exhibit sparse to abundant, laminated pelletal fabrics. The accumulation of pelleted, fossiliferous, organic-rich carbonate mud yaynesville even and wavy-lenticular laminated beds of very fine quartz silt and detrital clay reflects the mixed accumulation of carbonate sediments generated within this basin and clastic sediments that came from outside it.
The calcareous particles include coccolithsbivalveand gastropod fragments, and calcispheres.
Sedimentological structures include burrowing, ripples, laminations, and current laminations related to turbidites Fig. Haynesville mudstones contain abundant carbonate, whereas Bossier mudstones are dominantly clay and quartz, indicating a shift from transgressive fkrmation environment to progradation of clastics due to highstand deposition in the Bossier.
In many geological reports and journal papers, the Haynesville Shale was classified as part of the Bossier Shale, although they are now classified as separate formations.
Geologyy Haynesville Shale is a lithological heterogeneous, often organic-rich, mudstone. Aalenian Bajocian Bathonian Callovian. The mechanisms 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. Ternary diagram showing Bossier and Haynesville mineralogical data from x-ray diffraction analyses.
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 Anderson Controls on reservoir quality and productivity in the Haynesville Shale, northwestern Gulf of Mexico Basin.
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 haynesvilel leasing, leasing bonus payments and well production results.
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.
Hayndsville area and structural controls of the Upper Jurassic northeastern Gulf of Mexico basin. The Gilmer Limestone and Buckner Anhydrite members represent coastal and shallow marine deposits, which form along the northern boundary of the basin in which the Haynesville Shale accumulated and separate it from contemporaneous undifferentiated nonmarine geplogy that occur beneath Arkansas further north.
Basins colored in green; uplifts colored in red. Bioturbated calcareous mudstone showing abundant calcitic bioclasts in organic-rich matrix. 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.
Northeast Marcellus Shale Utica Shale.
Gulf Coast Association of Geological Societies. News and Current Events. 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 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 Fig.
Recently, Haynesville production of 5. As a result of rising gas prices 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.
That makes directional drilling and hydraulic fracturing popular avenues for tapping into its gas reserves. The mudrocks contain a complex filetpye framework of carbonate, quartz, and clay Fig.
The Haynesville Formation consists of marine and coastal plain limestone, shale, mudstone, and sandstone. 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. They comprise the western boundary of the ancient shelf basin within which Haynesville Shale accumulated. Haynesville burrowed mudstone facies showing carbonate and siliceous grains, peloids, and burrows filled with calcite B.
A documentary film entitled “Haynesville: As a result of these restrictive conditions, fileype conditions frequently occurred during the deposition of the sediments that form the Haynesville Shale. In addition formatiion its overall size, the Haynesville is known for its high porosities. From Wikipedia, the free encyclopedia.
