Preventing Differential Sticking
The Drilling Programme shall indicate any permeable formations which may lead to differential sticking, particularly if the risk of differential sticking is considered to be high.
Data Acquisition
An estimate of the problem formation pressure shall be made using the best offset data available. If good, and recent, RFT, or producing well information is available, it should be used to estimate the expected formation pressure.
On an appraisal wells where differential sticking has been identified as a potential problem, taking an RFT measurement should be considered. The risk of sticking the logging . . .
