Semi-submersible Drilling Rig and Drilling Equipment
Journal of Ocean Engineering and Technology, 2012Co-Authors: Byoung-ky An, Hyun-jung OhAbstract:An exploration well is drilled where oil or gas potential is shown by a seismic survey and interpretation. With the advance of Drilling technology, most of the easily accessible oil had been developed by the end of the 20th century. To satisfy the ever increasing demand for oil, and bolstered by high oil prices, the major oil companies started to drill in deep water, which requires a deep offshore Drilling unit. Offshore Drilling units are generally classified by their maximum operating water depth. Many semi-submersible rigs have been purpose-designed for the Drilling industry as the allowable Drilling water depth has become deeper by the developed technics since the first semi-submersible was launched in 1963. Semi-submersible rigs are commonly used for shallow to deep water up to 3,000 m. Drilling Equipment such as a top drive, blowout preventer, drawworks and power system, mud circulation system, and subsea wellhead system are explained to help with an understanding of offshore Drilling procedures in the oil and gas fields. The objective of this paper is to introduce the main components of a semi-submersible rig and, by doing so, to raise the awareness of offshore Drilling, which accounts for over 30% of the total oil production and will continue to increase.

Chpater 11 – Specialized Downhole Drilling Equipment
Air and Gas Drilling Field Guide, 2020Co-Authors: William C. Lyons, Reuben L. Graham, Greg D. HawleyAbstract:Publisher Summary There are two downhole Drilling devices used with air and gas Drilling technology: down-the-hole hammer (DTH) and the progressive cavity positive displacement motor (PDM) Drilling motor. The DTH can only be used with an air or other gas Drilling operation with unstable Drilling fluids. The PDM was originally developed for use with incompressible Drilling fluids, but operates on unstable foam, aerated, and stable foam Drilling fluids. PDMs are nearly always used to drill directional boreholes. There are two basic designs for the DTH. One design utilizes a flow path of the compressed air through a control rod down the center hammer piston and then through the hammer bit. The other design utilizes a flow path in the wall of the hammer housing. This type of hammer design allows for the flow of gas in this small annulus passage and then through the hammer bit. The most commercially successful positive displacement fluid downhole motor has been the progressive displacement “cavity” motor. The driving shaft of these motors is a rigid shaft composed of helical lobe repeating sections and is denoted as the rotor. Downhole pneumatic turbine motors are the only specialized downhole Drilling Equipment that can be used with dry compressed air (or other Drilling gases).
