Utica Shale drilling and production began in Ohio in 2011. Ohio as of 2013 is becoming a major natural gas and oil producer from the Utica Shale in the eastern part of the state. [10] Map of Ohio Utica Shale drilling permits and activity by date. [11] [12] In 2011 drilling and permits for drilling in the Utica Shale in Ohio reached record highs ...
Geologic map for the Anadarko Basin showing thickness of strata between the Silurian Hunter Group and the Pennsylvanian Desmoinesian Anadarko Basin Geologic Cross Section. The Anadarko Basin is a geologic depositional and structural basin centered in the western part of the state of Oklahoma and the Texas Panhandle, and extending into southwestern Kansas and southeastern Colorado.
Drilling along the underside of a reservoir-constraining fault allows multiple productive sands to be completed at the highest stratigraphic points. Drilling a "relief well" to relieve the pressure of a well producing without restraint (a "blowout"). In this scenario, another well could be drilled starting at a safe distance away from the ...
The Salina Group or Salina Formation is a Late Silurian-age, Stratigraphic unit of sedimentary rock that is found in Northeastern and Midwestern North America.Named for its Halite beds, the phrase "Salina Group" was first used as a descriptive term by James D. Dana in 1863.
The first response to detecting a kick would be to isolate the wellbore from the surface by activating the blow-out preventers and closing in the well. Then the drilling crew would attempt to circulate in a heavier kill fluid to increase the hydrostatic pressure (sometimes with the assistance of a well control company). In the process, the ...
The long history of sedimentary deposition in the Williston Basin included deposition of rocks well suited to serve as hydrocarbon source and reservoir rocks. The basin's oil and gas fields are found in a wide range of geologic ages, as indicated by the generalized stratigraphic column. [4]
In 1926, a partnership consisting of Mid Kansas Oil Company (part of The Ohio Oil Company, the ancestor of Marathon Oil) and Transcontinental Oil, drilled an exploratory well, the Yates No. 1-A, on the Yates ranch into the San Andres formation approximately 1,000 feet (300 m) below ground surface, and hit a rich productive zone, producing a ...
An experimental vertical well is being drilled in McLennan County (near Waco) to assess the potential for drilling along the Ouachita Fold, a geological barrier which defines the southern limit of the Barnett Shale. Although horizontal wells are now the norm, as of early 2013, some vertical wells were still being drilled in the Barnett. [14]
