Wireline coring/open center reaming: Technical problems and solutions
- Fehr (Gregory), Las Vegas, NV (United States)
At the 1993 ASME Energy Technology Conference, a paper, ``Field Experience with Wireline Coring through a Dual Wall Drilling System``, was presented. It described the initial scientific drilling which started in the spring of 1992 using wireline coring within a 9 5/8 inch dual wall drill pipe through an open center reaming bit, and some of the improvements made since the prototype drilling tests. New and as yet unsolved problems were identified. This follow-on work brings the industry up-to-date with a survey of how these difficulties have been solved, or, if not solved, the status of the effort made for each of the air coring/reaming technical challenges on the Yucca Mountain Site Characterization Project at the US Department of Energy Nevada Test Site.
