Precautions are taken to prevent leaks from occurring. Specialized equipment, such as a blowout preventer (BOP), is installed on every well and continually monitors pressure levels during the drilling process. An automatic alarm can sound if the pressure becomes too high or too low. and loss of well control.
All wellsites are equipped with a blowout preventer (BOP) during the drilling phase. A BOP is a large set of valves at the top of a well that can be closed immediately if warranted by a change in pressure. BOPs are critically important to the safety of the crew and are inspected, tested and refurbished at regular intervals.
In addition to BOPs, each rig is equipped with a pit volume totalizer, also known as a pit-level indicator, which continuously monitors the level of the drilling mud in the mud tanks. If the mud level drops too low or rises too high, the alarm sounds to warn the driller of a loss of circulation or a kick, which is a flow of reservoir fluids into the wellbore during drilling operations.
Chesapeake trains all supervisory-level personnel on location and requires recertification in well control every two years. Precautions are taken to prevent gas leaks from occurring.
