CoilTools Jar-Thru Mechanical Indexing Tool
CoilTools 'Jar-Thru' Indexing Tool has been designed specifically for fishing operations and provides incremental rotation of BHA components simply by setting down weight until the required orientation is achieved. The increased tensile strength and shorter length allow the tool to be run below jars.
A high strength, dual clutch mechanism 'locks in' applied torque / rotation, fixing the orientation until the next cycle. The tool can be activated multiple times simply by picking up and setting down weight again. 3 Inches of downward travel will produce 130 degrees of rotation which ensures a different tool orientation at the end of each cycle.
The tool can be used to orientate an overshot guide during fishing operations to engage a difficult fish, to rotate a grapple onto a fish for maximum engagement or to bypass ledges or other wellbore restrictions. The thru bore provides drop ball access allowing a hydraulic disconnect to be run below.
