Which practice helps manage connection gas effectively?

Managing connection gas effectively is crucial in drilling operations, especially to prevent hazards associated with gas influx and pressure control. Controlling the drilling rate to limit connection gas slugs is the best practice because connection gas usually occurs when drilling fluid is not adequately managed during the period when the drill string is disconnected from circulation. By controlling the drilling rate, you can minimize the volume of gas that enters the wellbore during connections, thereby reducing the size of gas slugs that can accumulate and lead to potential issues such as kick or blowout.

When the drilling rate is kept within an appropriate range, it helps to maintain a stable well pressure and minimizes the chances of gas entering the system. This proactive approach allows for better management of wellbore pressure and enhances safety during operations. In addition, it enables operators to better prepare for any influxes of gas, maintaining the integrity of the well and ensuring safe drilling practices.
