Traditional percussion sidewall cores have dropped significantly in lower unconfined compressive long been considered of limited value...

..., 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...

... 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...

..., but the application of a formation pressure tool and sidewall cores confirmed presence of movable hydrocarbons and allowed us to make a reasonable estimate of the producible volumes. This paper will demonstrate that as we move from the easy gas to the more difficult, the importance of the log data and the expertise...
