Print this pageABSTRACT: Well Logging and Completion Technology for Horizontal Wellbores
Walter H. Fertl
In highly deviated and, particularly, horizontal wellbores, special hardware systems guide, push, and/or pump the logging instrument assembly toward the bottom, i.e., the end of the wellbore, and to log the interval of interest.
The present paper discusses basic pipe-conveyed logging (PCL) systems and the coiled-tubing-conveyed (CTC) system for completion and perforating applications in horizontal well bores, which already
have proven successful in Europe, the USA, and Canada. Open- and cased-hole field applications, with special emphasis on the Cretaceous Austin Chalk in Texas and the Bakken Shale in Wyoming, will illustrate today's technology and review advantages and possible constraints of these well logging and completion techniques.
