Many gas wells cease production due to liquid loading,
but a technology development program is successfully making progress to combat the problem and extend their working lives.
The extraction of gas from wells often declines as the
pressure within the reservoir falls. As the pressure drops,
the wells begin to load with liquid and methods to remove
water are required to maintain gas flow.
U.K.-based Corac Energy Technologies (CET) is developing applications that it says enhance performance in oil
and gas production. It is working with several partners to
develop innovative, compact turbocompressors.
Demonstrating that the technology has captured the interest of oil and gas majors, CET recently signed agreements with Tullow Oil and BP to develop the applications.
CET’s compressors have proven themselves in industrial applications in Europe and the Far East, logging more
than 20,000 hours of maintenance-free operation. The
company’s intellectual property portfolio includes more
than 40 patents plus several pending and eight European
According to the company, the goal of the downhole
compressor development program sector was to apply the
“unique technical characteristics” of the CET
compressors to the oil and gas sector. It said
the compact, lightweight and frictionless
qualities of its equipment can provide long
