Deliquification of a low-pressure gas well requires a different approach, tools, and staffing than artificially lifting an oil well. There is no “silver bullet” that will solve all deliquification ...

Due to strong stress sensitivity resulted from unconventional tight formationsit is of practical interest to formulate a reasonable pressure drawdown plan to improve gas extraction recovery. The ...

This study focuses on the Joule–Thomson (J–T) valve of a low-temperature separator in a domestic offshore oil and gas field. To address the lack of systematic research on the existing control logic, a ...

Venting riser gas during a gas influx event relieves riser pressure and enables pit monitoring, but it can lead to uncontrollable discharge. A novel fixed-choke, constant-outflow (FCCO) method fixes ...

Well control in offshore drilling is the disciplined set of practices and equipment used to keep bottomhole pressure within the safe operating window (between pore pressure and fracture pressure), ...
