And these days, one of the most important things on the list when we drill for oil is to protect our very drilling rig from an accident such as that which caused the current disaster. When it leaks too easily: oil or gas wells catch on fire, but a blowout is still dangerous for everything else. Now, in order to prevent that from happening, we have this one device-- right here called a blowout preventer BOP. The BOP can be classified differently depending upon the type and differs in its own characteristics based on its operation.
Blowout preventer is a safety equipment that keeps oil and gas inside the wellbore during drilling. In order to prevent the release, it seals the well in hydraulic rams. We tune the rams to be very quick as well but because these rams are massively strong you can get a real good hydraulic coupling with this. We would use a different BOP based on the type of well we expect to encounter and levels of pressure.
An Annular BOP — Instead of simply restricting the pipe, a flexible rubber component can fold and unfold to block off an opening. This is great for wells that have out of gauge casing (big pipe that holds everything in) or drill pipe (smaller pipe that goes down into the well). Because it can bend providing less seal around the hole as the opening changes through the rock while being drilled.
Ram : can close and seal the well with large steel parts. ( BOP type) These are the best choice if you have a well with casing and drill pipe that is all the same size. The Ram BOP is a powerful clamp that can offer the high-pressure seal to drill at higher pressures.
Variable Bore Ram Valve (VBOP) – Blowout preventer with the ability to change some of its parts. Because we also start our trips drilling and pull multiple times, it helps to be able to fish with the same flex liner. And it shuts lightning fast when needed, guaranteeing a solid seal every time.
Hence selecting the best blowout preventer for our drilling operations is very critical. Using the wrong BOP may potentially bring in blowouts which are a risk not only to people working on the rig but would also result to enormous expenses as they refit for replacement and wastes resources.
Variable Bore Ram BOP – Best for wells with frequent size changes. As the name suggests, way puzzles are gatling shaped and unique among existing nozzle styles in that they can accommodate multiple pitches of drill string (bore size) within one completion - drastically reducing re-entry time-and- increasing strength for sealing.
