CREEP DETERMINATION TECHNIQUE

摘要

A method for determining an amount of creep for a tool on a cable and positioned in a well at an oilfield. The method includes moving a winch at a surface of the oilfield to effect movement of the tool below the surface in the well. The winch may the n be stopped with the tool still in the well, but frequently the tool will contin ue to move, or "creep", for some time after the winch is stopped. After the winch is stoppe d, data may be recorded indicative of movement of the tool. This data may then be used f or the determining of the amount of creep.
