Abstract
A technique enables determination of changes in length of a conveyance deployed between a surface vessel and a subsea installation. The technique allows information to be obtained on the relationship between length of conveyance spooled out or spooled in at a surface location and the depth and/or speed of an intervention well tool deployed in a well. The information can be used to determine the actual depth of the well tool deployed in the well for the intervention operation.
