Gas-Assisted Gravity Drainage (GAGD) Process for Improved Oil Recovery

Proceedings of International Petroleum Technology Conference, 2009
Water Alternating Gas injection (WAG) or Simultaneous Water and Gas Injection (SWAG) floods have been proposed as very good solution to overcome gravity segregation and better EOR performance in compare to conventional continuous gas injection (CGI). However WAG-Based processes cause some problems associated with increased water saturation including ...

Studies on Improving Drainage Gas Recovery Efficiency of Gas Wells

2018
Nearly forty percent of gas wells in Daqing Oil Field have been producing water, resulting in reduced production and increased cost. Reasonable measures are required to improve drainage gas efficiency of these wells. Based on the influencing factors of drainage gas recovery process, efficiency could be improved in three aspects, including optimizing ...

Effect Evaluation of Drainage Gas Recovery by Velocity String in Sulige Gas Field

2018
The universal features of the gas wells in Sulige gas field are low pressure, low production rate, and the liquid-carrying capabilities of the wells that are poor. Accompanied with the gas well entering the process of middle and late life span, the pressure of the well bottom gets low and the liquid-carrying capability of the well becomes poorer ...
