Igws ole igw says: You must pipf that overall hydrostatic pressure is still able to control reservoir fluid to accidentally come into the wellbore. Ensure that the wellbore is clean prior to continuing the operation. Tagged how to free stuck pipestuck drill pipestuck pipe. View all posts by DrillingFormulas.
These following instructions are guide lines on how to free the stuck drill string caused by wellbore geometry. Continue jarring down with maximum trip load and apply torque into drill string. Circulate at maximum allowable flow rate.
High flow rate hopefully can wash the contact area so the effect of differential stuck is reduced. Do not use high flow rate because it will make vree stuck situation became worse and you will not be able to free the pipe forever.
Free Stuck Pipe Caused By Wellbore Geometry These fileype instructions are guide lines on how to free the stuck drill string caused by wellbore geometry. Stuck Pipe Summary I have posted several stuck pipe articles and I would like to summarize all articles in one page so you can use it for future reference.

How To Free Stuck Pipe (Oilfield)
Apply maximum allowable torque in the drill string and work down torque to the stuck depth. Slack off weight of string to maximum sit down weight. DO NOT apply torque in the drill string while jarring up. It is very important to apply low flow rate because if high flow rate is diletype, the stuck situation becomes worse.

Circulate with low flow rate — psi pumping pressure. It will give you stuci ideas which you can apply for your operation. On the other hand, if the drill string gets stuck while moving down, jar ppie with maximum trip load. Increase flow rate and circulate to clean wellbore at maximum allowable flow rate.
