BOP | BLOW OUT PREVENTER
Blowout Preventers (BOP) Stack is one of the rig components that is used to seal the wellbore and thereby contain a kick ( check drilling kick ). Two main types of BOP preventers are in use in the industry (both types are discussed below). In this article, we shall discuss its BOP blowout preventers stack classification, components & types. API Classification For BOP Blowout Preventers Components API classification for BOP blowout preventers equipment is based on working pressure ratings. BOP stacks are rated to 2000 (2m), 3,000 (3m), 5,000 (5m), 10,000 (10m), or 15,000 (15m) psi. API Codes For BOP Stack Components As we mentioned, blowout preventer stacks are rated to 2000, 3,000, 5,000, 10,000, or 15,000 psi. A preventer stack normally consists of an annular BOP preventer on top, followed by one or more (typically up to three) ram-type preventers (Fig.1). The inclusion of a full-bore drilling spool makes it possible to connect the kill and choke lines (Adams 1979b,
