Gas extraction from drilling fluid and its analysis remain a crucial source of information for drilling any well, serving to continually enhance both operational safety and reservoir evaluation. Through several decades, the gas extraction device (gas trap) has seen some improvements in efficiency and consistency of agitation and minimizing of inconsistent ambient air dilution - implemented in the QGMTM* gas trap.Constant Volume Trap (CVT) implementation, largely by controlled pump rate of mud into a non-immersed gas trap, was introduced more recently to address the open bottom gas trap issues such as inconsistent fluid refresh rate, eddy mud resampling, and inconsistent mud level or volume. Additionally, it allowed mud to be sampled further upstream of the flowline improving early detection and quantification by capturing volatile hydrocarbons before they full escape into the atmosphere.Unfortunately, many CVT manufacturers did not integrate QGMTM design characteristics into the system and thus still failed to deliver consistent gas extraction benefits. Furthermore, excessive number of moving parts in the popular designs, coupled with poor pump hose material leading to more rapid cuttings build up caused by finer filter mesh, and frequent agitator blade failures all contributed to minimal adoption of CVT-QGM type gas extraction.PFI-750 is designed to deliver identical benefits as with a QGMTM trap and uses high performance hose material for much longer CVT service life. With integration of a variable frequency drive and precision gear speed reducers, constant fluid injection rate is assured, regardless of motor power / voltage variations.With precisely maintained mud sample refresh rate, industry-proven mud agitation effectiveness and minimal maintenance, PFI-750 offers the most viable path for CVT-QGM to become the gas extraction standard device used in every rig by the operator, drilling contractor and service company.
