Q: What is wellhead compression?
A: It is the use of a compressor to draw on wellbores thereby reducing backpressure and also increasing pressure into the sales line. Reduced backpressure allows hydrocarbons to more freely enter the wellbore. The compressor may be set at the tank battery to service many wells instead of an individual wellhead.
Q: What type of compressor is best suited for wellhead compression?
A: To answer this question you need to know the proposed inlet and outlet pressures, volume of gas, analysis of the gas, altitude, and lease conditions.
Q: What compressors are best suited to pull a vacuum?
A: Rotary screw, rotary vane, and liquid ring.
Q: What are the best applications for a reciprocating compressor?
A: Where you need to move high volumes of sweet gas at high discharge pressures - can be staged for higher pressures.
