Stickiness factor--A new way of looking at stuck pipe
The stickiness factor is an empirically derived number strongly related to the chances of freeing stuck pipe in a well. Since stuck pipe costs are largely dependent on the ability to free stuck pipe and avoid sidetracking a well, it follows that reduced stickiness factors should result in reduced stuck pipe costs. The stickiness factor is commonly lowered by reducing the API-fluid loss of the mud, reducing the bottom-hole-assembly length, or setting casing. The stickiness factor is based on a study of Gulf of Mexico wells drilled by Exxon Company, USA. Therefore, it will not necessarily apply to well in other areas. The factor does not predict when pipe will stick, but simply predicts the chance of freeing pipe that has already been stuck. The stickiness factor will also help evaluate various spotting fluids and fishing techniques since it indicates the relative difficulty (chance of success) of a soaking or fishing job. Finally, a reduced stickiness factor should reduce the chances of sticking pipe.
