Stuck Pipe Prevention and Fishing Operations
For drillers, assistant drillers, toolpushers, drilling supervisors and drilling engineers. It covers the three mechanisms of stuck pipe, how to read torque, drag, pressure and returns, and the hole cleaning and tripping practices that prevent sticking. It then covers how to identify the mechanism and take the first actions when the pipe sticks, how jars, spotting fluids, freepoint and back-off work, and how to plan a fishing job.
