Frequently Asked Questions: Blow Out Preventers (BOPs)


What is a BOP?

BOP refers to ‘blowout preventers’. Blowout preventers are large valves on the top of a well that may be shut down if the rig crew is unable to control formation fluids, a situation often indicated as ‘well-kick’ in the oilfield parlance.


What are the different types of BOP?

Fundamentally, there are two types of blowout preventers- Annular and Ram BOP. Ram-type BOPs can be further divided into Pipe Rams, Blind Rams, Shear Rams and Blind Shear Rams.


How does a Ram-type BOP work?

The functioning of Ram-type blowout preventers is very much similar to a gate valve, but uses a pair of opposing steel plungers, rams. They include rubber-faced steel rams that are brought at one point to shut the annular space outside the string of pipe in a well or open hole.


What is the usual BOP Stack Configuration?

Generally, the ram preventers are on the bottom and the annular preventers at the top in a model BOP stack configuration.


What are the primary control methods for BOP?

Basically, there are five ways by which a BOP can be controlled- Hydraulic Control Signal, Electrical Control Signal, Acoustical Control Signal, ROV Intervention and Deadman Switch.


Why is it important to clean BOPs?

A dirty blowout preventer can be very dangerous as it will interfere with the internal working and thus, it is extremely important to clear the sand, junk and debris that accumulate within the cavities. Maintaining the cleanliness of the BOP will enhance safety and would bring about a reduction in operational costs.


Are there any guidelines for manufacturing of BOPs?

Yes. The design, manufacture and operation of BOPs is conducted in sync with the following standards: BSEE 2014, API 2004a, API 2004b, API 2012, PSA 2014a, PSA 2014b, NORSOK 2012, NORSOK 2013, API RP53.


How important it is to test BOPs?

It is extremely important to inspect, test and revamp the blowout preventer system at regular intervals owing to its decisive role in maintaining and enhancing the safety of the crew. Risk assessments are conducted and appropriate attention is directed to check if the operations are in sync with the type of the well and legal specifications.


How does an Annular BOP work?

The Annular Blowout Preventer works on hydraulic pressure. The equipment makes use of a ring of reinforced synthetic rubber which serves as a packing unit on all sides of the well bore to seal off the well.


What are BOP stacks?

A BOP stack is a way of installing blowout preventers in a particular configuration so that, the wellhead pressure from an oil well can be effectively controlled. Usually, two or more BOPs are connected on one stack. A regular stack of blowout preventer is composed of one to six ram-type blowout preventers and alternatively, one or two annular-type blowout preventers.


What are Internal BOPs?

Primarily used in drilling operations during a blowout, an internal blowout preventer is also referred to as an ‘inside blowout preventer’. In order to release the pressure, the tool is connected to a drill pipe. While a kick occurs in the drill string, this type of valve protects the rotary swivel, standpipe, mud pipes and drilling hose.


What are the new technologies that have come up w.r.t BOPs?

Since the time of invention, the blowout preventers have come a long way and technological developments like e- BOP, One Trip, Petrobras Initiative and the New Service Model are redefining the future of rig safety.


Is there an option to rent BOPs?

Yes. Considering the huge expenses involved in the purchase of blowout preventers, there are companies that specialise in renting out BOP equipment.
