Abstract

An indexing tool (10) for a wellbore string (100) is described. The indexing tool is suitable for assisting a tool connected thereto in passing an obstruction in a well. The indexing tool (10) comprising: - a first tubular body (12); - a second tubular body (13) for receiving a portion of the first tubular body (12); - a retention means (18) for preventing the second tubular body (13) from sliding off of the first tubular body (12) when the indexing tool (10) is exposed to tensile forces in an axial direction; and - a protruding element (16) fixedly connected to the second tubular body (13); wherein a recess (14) is provided in connection with the first tubular body (12) for receiving and guiding the protruding element (16), said recess (14) extending in a circumferential and axial direction with regards to the first tubular body (12); wherein the indexing tool (10) further comprises: - a sleeve (19) movably arranged around a portion of the first tubular body (12), wherein the sleeve (19) comprises the recess (14); - an engagement means (20) arranged for: - engaging with the sleeve (19) and fixing the position of the sleeve (19) with regards to the first tubular body (12) when the first tubular body (12) is pulled in an axial direction away from the second tubular body (13), and for - disengaging from the sleeve (19) when the indexing tool (10) is exposed to external compressive forces such as from the wellbore string (100) being pushed against an obstruction in the well, such that the sleeve (19) rotates independently from the first tubular body (12). A wellbore string (100) comprising the indexing tool (10) is also described.
