  • Openhole logging without a wireline in high-angle wells

    Peter Elkington

    Pipe-conveyed logging (PCL) failure rates as high as 1 well in 4 are most often attributed to failure of the wireline and wet-connect system, and although LWD is a more elegant solution, measurement quality still needs improvement. PCL has the added drawback of being slow, and LWD remains too expensive for many onshore locations. This article discusses a new, more reliable way of performing PCL that is especially well-suited in rugose, high-angle wells. Brief case studies are also presented.
