Dec 20, 2021 · A Blowout Preventer (BOP) Control System as one of the drilling rig components, is a high-pressure hydraulic power unit fitted with directional control valves to safely control well kicks and prevent blowouts during drilling operations.

Oct 9, 2020 · The most common surface BOP stack configurations include using a set of two BOPs to control the pressure of oil in an oil well. A typical stack usually has between one to six stacks of ram-type preventers and sometimes one or two annular-type preventers.

Dec 23, 2017 · Two main types of BOP preventers are used in the industry (both types are discussed below). This article will discuss its BOP blowout preventers stack classification, components & types. API classification for BOP blowout preventer equipment is based on working pressure ratings.

The surface BOP stack must include at least four remote-controlled, hydraulically operated BOPs, consisting of one annular BOP, one BOP equipped with blind shear rams, and two BOPs equipped with pipe rams.

The scenario considers drilling operations using a surface BOP in combination with a Subsea Disconnect System (SDS) in Gulf of Mexico (GoM) from a floating production unit with drilling capabilities.

The BOP stack rating of used BOP"s (> 5 years old) should be at least 10% higher than the maximum expected surface pressure that could be encountered during drilling and workover operations. The safety margin may become less than 10%, depending on …

the BOP, risks associated with the han-dling of the riser, and availability of drilling rigs for relief well drilling in the event of a blowout. If a high-pressure riser and surface BOP (SBOP) system can be demonstrated to be as safe or safer than current oilfield practice, many of the risks could be eliminated. To date no detailed design ...

Fluids specifically formulated for Blow-Out Preventer (BOP) controls and motion compensator systems used for drill rig operations. High level properties and benefits include excellent stability, corrosion protection, anti-wear lubrication properties and a …

The application of Surface BOP Technology (Surface Blowout Preventer) is a well-proven method of extending the water depth operating capacity of a floating mobile offshore drilling unit.

Feb 26, 2002 · This paper presents an overview of the comprehensive Management System & Design Guidelines created to safely implement Surface BOPs in variety of environments. In particular, the Management System enables the use of the Surface BOP in environments other than the benign met ocean/formation conditions where …
