..., even for wireline operations. Formation pressures can exceed 30,000 psi, and differential pressures over 5,000 psi also exceed the capabilities of traditional rotary coring tools. New technology has been introduced to enhance the recovery of rotary sidewall cores to improve operations and capabilities...

... for cost efficiency, conventional full-core acquisition is often curtailed and subsurface teams must rely on percussion or rotary sidewall core samples. This choice is made even though it is known that for many core analysis measurements, the accuracy of the measurement is directly proportional to the pore...

... in Colorado Springs, Co, USA, May 14-18, 2011. ABSTRACT Wireline sidewall cores have a well-established role in the formation evaluation program in providing key rock properties. While they provide a subset of the exhaustive information obtainable from continuous core, for reasons of operational efficiency...
