Only those proposals judged as the greatest value based on scientific and technical merit were scheduled for implementation. SAS panels provided advice on drilling proposals to both proponents and IODP management. Drilling proposals were accepted twice a year, in April and October, and could be submitted to IODP electronically via their website.
During this time Revelle sought to have SIO as prime contractor or administrator of a drilling program. Proposals to NSF to support LOCO were not successful, however, and LOCO dissolved in April 1963. [4] The Glomar Challenger, launched in 1968, was the drill ship for NSF's Deep Sea Drilling Project.
Drilling engineering is a subset of petroleum engineering. [1] Drilling engineers design and implement procedures to drill wells as safely and economically as possible. [1] They work closely with the drilling contractor, service contractors, and compliance personnel, as well as with geologists and other technical specialists.
Borehole Mining (BHM) is a remote operated method of extraction (mining) of mineral resources through boreholes based on in-situ conversion of ores into a mobile form (slurry) by means of high pressure water jetting (hydraulicking). This process is carried-out from a land surface, open pit floor, underground mine or floating vessel through pre ...
Geotechnical surveys involve a combination of sampling, drilling, in situ testing as well as laboratory soil testing that is conducted offshore and, with samples, onshore. They serve to ground truth the results of the geophysical investigations; they also provide a detailed account of the seabed stratigraphy and soil engineering properties. [ 23 ]
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.
The well geometry therefore is less aggressive and the wellbore (wall of the well) is smoother than those drilled with a motor. This last benefit concerns geoscientists, because better measurements of the properties of the formation can be obtained, and the drillers, because the well casing or production string can be more easily run to the ...
Extended Reach Drilling (ERD) is directional drilling of very long non-vertical wells. The aims of ERD are: a) to reach a larger area from one surface drilling location, and b) to keep a well in a reservoir for a longer distance in order to maximize its productivity and drainage capability.
