| The course will cover stuck pipe prevention- the diagnosis of all stuck pipe mechanism- first actions after stuck- freeing methods and techniques and how to analyse the data to know which type of stuck. Jar and jar placement will be discussed in details.  Introduction for stuck pipe mechanism- Discuss the impact of stuck pipe and Most likely timefor stuck pipe incident.  Causes of Stuck Pipe- diagnosis of stuck pipe mechanism and first action for every mechanism.  Differential Sticking  Hole Pack-off - Bridging. Will Discuss Hole cleaning review and Formation Related causes (Geo-pressured- Reactive- Unconsolidated- Mobile- Fractured/Faulted formations)  Wellbore Geometry Related causes of Stuck Pipe: - Key Seating - Junk - Cement Blocks - Green Cement - Under gauge Hole - Collapsed Casing - Inadequate Hole Cleaning - Summary of causes. All stand and name 1 cause  Jars and Accelerators  Basic jar theory  Hydraulic vs. Mechanical jars  Pump open forces- Case study for POF calculations  Jar placement techniques  Jar accelerators  Trouble shooting jar failure  Running jar in tension vs. compression  Summary of good jarring practices • Drilling Practices for prevention of Stuck Pipe  Top Drives (advantages/disadvantages)  Good drilling practices  Making connections  Good tripping practices  Video for Hole cleaning affected factors • Stuck Pipe incident calculations and Summary of freeing procedures  Pre-recorded data  Stretch readings and Estimating stuck pipe depth  Maximum over pull calculations for tapered and single string  FPIT and Back-off technique. • Simulator Practical exercises  Participants will go through practical simulator Exercise as practical training to simulate the stuck pipe incident and first action required to free the sticking pipe and simulate the jarring operation till the string come free. Every participant will share in the simulator exercises. • Actual Case study  Participants will go through actual case study to discuss and evaluate the sticking mechanism they will be working as a group to evaluate what was done and comments on the actual case study. Each Candidate will stand and discuss the route his specific role in stuck pipe prevention.  Participants will go through exercises to calculate and evaluate the maximum over pull and freeing pill techniques to spot and circulate out of hole. |
