When a gas well velocity drops below the critical velocity to lift produced fluids out of the wellbore a loading effect occurs which restricts gas production. Once the gas well has built up enough gas pressure to overcome the hydrostatic pressure of the fluid then the well will “unload” and resume normal gas production until the cycle repeats.
To alleviate this problem chemical foamers have been used to reduce surface tension of the load fluid and allow the fluid to be lifted to the surface so gas wells produce more consistently providing gas well optimization.
Prochem’s foamers improved Shell’s gas well optimization. This site used 4 liters per day of foamer at a cost of approximately $5/day totaling $20/day. This increased condensate production $189/day and gas production $1024/day.
