The primary safety control devices for well drilling are blowout preventers (BOPs), which have been used for nearly a century in control of oil well drilling on land. The BOP equipment technology has been adapted and used in offshore wells since the 1960s. The inspection and repair of subsea BOPs are much more costly, and the consequences of ...
As technology has advanced, more modern drillers have better control of the overall well. Oil well control is the management of the dangerous effects caused by the unexpected release of formation fluid, such as natural gas and/or crude oil, upon surface equipment of oil or gas drilling rigs and escaping into the atmosphere.
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.
RSES – responsible for safety and environment on site; RSPP – a publicly-traded oil and gas producer focused on horizontal drilling of multiple stacked pay zones in the oil-rich Permian basin [citation needed] [clarification needed] RSS – rig site survey; RSS – rotary steerable systems; RST – reservoir saturation tool (Schlumberger) log
[4] [5] During drilling operations, complex accidents such as gas invasion and overflow are prone to occur. [6] In addition, deep strata have poor diagenesis , weak pressure bearing capacity, so leakage is easy to happen, the risk of well control is high, and the treatment is difficult, which impact on deepwater wellbore integrity seriously.
Subsea wells have pressure control equipment located on the seabed or between the riser pipe and drilling platform. Blowout preventers (BOPs) are the primary safety devices designed to maintain control of geologically driven well pressures. They contain hydraulic-powered cut-off mechanisms to stop the flow of hydrocarbons in the event of a loss ...

Well completion is the process of making a well ready for production (or injection) after drilling operations. This principally involves preparing the bottom of the hole to the required specifications, running in the production tubing and its associated down hole tools as well as perforating and stimulating as required.
