Stuckpipe and Fishing Operations

Who Should Attend:

For Drilling Supervisors, Rig Formen, Toolpushers, Drilling Engineers, Drillers ,Drilling Managers and Service Companies Objectives:

To reduce hole problems, learn about mechanisms leading to hole problems, interpret jarring envelopes, calculate stuckpipe forces. Learn about fishing tools and their selection


This course offers a practical approach to casing design methods and buckling analysis. The course is based on numerous wells drilled successfully in many parts of the world including the UK , Vietnam , Pakistan , Bulgaria , Tunisia , Egypt , Abu Dhabi , Russia , Indonesia , and Yemen. The course will cover conventional, horizontal and high pressure/ high temperature wells. Participants will be able to design casings for any well: onshore, offshore, high pressure and high temperature wells, horizontal and multilateral wells.
