Abstract (en)
[origin: WO9920871A1] Apparatus for recovering logging tools and the like from a wellbore as part of a drilling operation such as for oil wells, irrigation systems and the like. The apparatus comprises the use of a flexible connector member (44) in the form of a flexible wire rope, or strand, or cable which is provided with socket members (46, 48 or 146, 148) attached with resin (54) or by being swaged or crimped to the flexible member (44). The apparatus takes the place of the conventional rigid sinker bar assembly that causes safety concerns when used with a top drive housing.
