Comparative Study Between Hydraulic and Electric Bop Regarding Reliability

Abstract

The oil well drilling process is subject to unpredictable flows from inside the well, known as blowout. The Blowout Preventer (BOP) is a safety device used to seal the well if a blowout occurs, in order to ensure the safety and isolation of the well. This equipment works through a set of valves with hydraulic or electrohydraulic actuation and failures are very common. Electric-drive BOPs are recent bets to improve the performance of BOPs. This work makes a comparative study of the performance of hydraulic (BOPh) and electric (BOPe) BOPs, focusing on the reliability analysis.
