2. Duvernay Formation - Wikipedia

   en.wikipedia.org/wiki/Duvernay_Formation

   Shale gas and condensate is produced from the Duvernay Formation in central Alberta using horizontal drilling and multi-stage hydraulic fracturing. [5] $2 billion was paid for leases during 2010 and 2011. Prices for land remained high as of June, 2012 despite costs of drilling being expensive. Parts of the deposit show total organic carbon of ...

4. Kelly drive - Wikipedia

   en.wikipedia.org/wiki/Kelly_drive

   Simple diagram of a drilling rig and its basic operation. The kelly drive is #19. A kelly drive is a type of well drilling device on an oil or gas drilling rig that employs a section of pipe with a polygonal (three-, four-, six-, or eight-sided) or splined outer surface, which passes through the matching polygonal or splined kelly (mating) bushing and rotary table.

5. Well drilling - Wikipedia

   en.wikipedia.org/wiki/Well_drilling

   Well drilling is the process of drilling a hole in the ground for the extraction of a natural resource such as ground water, brine, natural gas, or petroleum, for the injection of a fluid from surface to a subsurface reservoir or for subsurface formations evaluation or monitoring.

7. Directional drilling - Wikipedia

   en.wikipedia.org/wiki/Directional_drilling

   Directional drilling (or slant drilling) is the practice of drilling non-vertical bores. It can be broken down into four main groups: oilfield directional drilling, utility installation directional drilling, directional boring (horizontal directional drilling - HDD), and surface in seam (SIS), which horizontally intersects a vertical bore ...

8. Petroleum geology - Wikipedia

   en.wikipedia.org/wiki/Petroleum_geology

   This is usually done by drilling more appraisal wells around the initial exploration well. Production tests may also give insight in reservoir pressures and connectivity. Geochemical and petrophysical analysis gives information on the type ( viscosity , chemistry, API, carbon content, etc.) of the hydrocarbon and the nature of the reservoir ...

9. Vertical seismic profile - Wikipedia

   en.wikipedia.org/wiki/Vertical_seismic_profile

   Walk-above VSPs (D) accommodate the recording geometry of a deviated well, having each receiver in a different lateral position and the source directly above the receiver. Salt-proximity VSPs (E) are reflection surveys to help define a salt-sediment interface near a wellbore by using a source on top of a salt dome away from the drilling rig.
