Oil well control involves monitoring and maintaining drilling fluid pressure to prevent crude oil from causing damage to equipment and causing a blowout. Drilling fluid is pumped down the well to balance oil pressure. An oil well control specialist prevents material from being pushed back into the borehole and uses modern technology to monitor and change conditions. Monitoring drilling fluid pressure is critical to prevent blowouts and potential disasters.
Oil well control is a comprehensive term used to cover a range of techniques and processes related to oil well drilling. It mainly involves carefully monitoring and maintaining drilling fluid pressure to prevent crude oil from causing damage to drilling equipment and causing a burst or gush, which resembles a geyser of petroleum rising from the ground at the well site . Drilling fluid is a liquid that is pumped down the well under pressure to balance the oil pressure.
The primary function of an oil well control specialist is to prevent material in the ground from being pushed back into the borehole, called a borehole, during the drilling process. In order to create and produce a successful well, the oil, which is called the formation fluid, must not be allowed to push out of the reservoir into the well until drilling is complete and the machinery to process the oil has been put in place. This is done using drilling fluid, which is pumped into the well under pressure to counteract the outward pressure of the forming fluid.
Monitoring drilling fluid pressure is critical to oil well control. If the drilling fluid pressure is not high enough, the forming fluid can push back into the well and cause an event known as a blowout or gush, which is essentially an explosion of oil from the well to the surface. This can be extremely dangerous and can lead to equipment damage, injury to workers, and violent explosions or very large fires that can be very difficult to extinguish. As long as the drilling fluid is kept at a proper pressure, it will prevent the forming fluid from entering the wellbore and causing such a potential disaster.
A specialist who performs oil well control work uses modern technology to monitor the condition of wells and to change conditions, such as drilling fluid pressure. The sensors help monitor drilling speed and pressure of drilling and forming fluids, as well as other conditions or events that may signal a potential problem. A knowledge of drill site geology can help the oil well control specialist make decisions about how to manage the drilling process to prevent a blowout.
