While we are familiar with most equipment manufacturers ranging from Terra, Zoomlion, TRACTO-TECHNIK, Ditch Witch, Huayuan, Goodeng Machine, Prime Drilling, Lianyungang Huanghai, Herrenknecht, CHTC JOVE, Drillto, Vermeer, XCMG, DW/TXS, Dilong and Toro, we prefer using the following four most often.
[pdf] The Well Control System or the Blowout Prevention System on a drilling rig is the system that prevents the uncontrolled, catastrophic release of high-pressure fluids (oil, gas, or salt water) from subsurface formations.
