What is the Barnett Shale Texas?
What is the Barnett Shale Texas?
The Barnett Shale is a geological formation and rich source of natural gas located in the Fort Worth Basin in Northeast Texas. The shale contains an estimated 40 trillion cubic feet of natural gas, making it the largest onshore natural gas field in Texas and potentially in the United States.
What is happening in the Eagle Ford Shale?
LONDON – Shale operators slashed their planned capital expenditure (capex) for 2020 to account for the oil price crash, which inevitably led to decline in drilling and completion activity in the Eagle Ford play.
What is the Barnett Shale formation?
The Barnett Shale is a geological formation located in the Bend Arch-Fort Worth Basin. It consists of sedimentary rocks dating from the Mississippian period (354–323 million years ago) in Texas. The formation underlies the city of Fort Worth and underlies 5,000 mi² (13,000 km²) and at least 17 counties.
How long will the Barnett Shale last?
A recent study by the Bureau of Economic Geology at the University of Texas estimates that Barnett still contains 44 trillion cubic feet of recoverable gas resources, and while annual production may decline from its current peak of 2 trillion cubic feet per year, substantial output is expected to continue through 2030.
What is Woodford Shale?
The Woodford Shale (a.k.a. Woodford Chert or Woodford Formation) is mostly Late Devonian in age with the uppermost part as Early Mississippian. Three informal members, related to environments of marine deposition, are recognized based on differences in palynology, organic geochemistry, and electric log response.
How many drilling rigs are in the Eagle Ford Shale?
Eagle Ford Oil & Gas Rigs A total of 86 rigs are drilling horizontal wells, one is drilling directional and one is vertical. Karnes County leads activity in the region with 16 rigs in production. See the full list below in the Eagle Ford Shale Drilling by County below.
How deep is the Eagle Ford Shale?
between 4000 and 12,000 ft.
This hydrocarbon-producing formation rich in oil and natural gas extends from the Texas-Mexico border in Webb and Maverick counties and extends 400 miles toward East Texas. The formation is 50 miles wide and an average of 250 ft thick at a depth between 4000 and 12,000 ft.
How deep is the Barnett Shale?
9500 feet
The Barnett shale formation and produces at depths of 6500–9500 feet with a production rate on the order of 0.5–4 million cubic feet per day (ft3/d) with estimates of three hundred to five hundred and fifty cubic feet of gas per ton of shale.
Where is the Cana Woodford Shale?
Table drawn from 906 frac stages.
What is the formation process of shale?
The process in the rock cycle which forms shale is called compaction. The fine particles that compose shale can remain suspended in water long after the larger particles of sand have deposited.
Is shale a rock or mineral?
Shale is the most common sedimentary rock, accounting for about 70 percent of the rock found in the Earth’s crust. It is a fine-grained clastic sedimentary rock made of compacted mud consisting of clay and tiny particles of quartz, calcite, mica, pyrite, other minerals, and organic compounds.
What is the size of a shale rock?
Shale is a clastic sedimentary rock that is made up of clay-size (less than 1/256 millimeter in diameter) weathering debris. It typically breaks into thin flat pieces. The specimen shown above is about two inches (five centimeters) across.
How is shale gas formed?
Shale is a compressed fine-grained type of sedimentary rock. It was formed from mud silt, clay, and organic matter. Shale gas is natural gas trapped within tiny pore spaces in shale formations. It is a hydrocarbon gas mixture. It consists mainly of methane.
