Gain insights into BOP manufacturers that are leading the segment, with Energy Dais Growth Quadrant. The Energy Dais Growth Quadrant is based on digital presence, revenue growth, user satisfaction and other factors.
The Blowout Preventers were invented in the year 1922 by James Abercrombie (1891-1975) and Harry Cameron (1872-1928) in response to the challenges involved in drilling operations. Since then, they have continued to transform the energy landscape by enhancing rig safety. In the year 2003, the American Society of Mechanical Engineers recognized and acknowledged the Cameron Ram-Type Blow-out Preventer as a ‘historic mechanical engineering landmark’.
Frequently Asked Questions: Blow Out Preventers (BOPs)
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.
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.
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.
Generally, the ram preventers are on the bottom and the annular preventers at the top in a model BOP stack configuration.
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.
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.
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.
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.
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.
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.
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.
Yes. Considering the huge expenses involved in the purchase of blowout preventers, there are companies that specialise in renting out BOP equipment.
