This course is designed to educate the candidates how to prevent fishing jobs and if they occur, what options and techniques are available to recover the fish or sidetrack the well.

By the end of this course delegates will be able to:

• Understand the key elements of stuck pipe
• Learn about the operations of drilling fluids, hole cleaning and cuttings
• Learn how to prevent fishing jobs
• Identify the occurrence of fishing jobs
• Understand the options and techniques available to recover the well fish or sidetrack
• Learn about drillstring design, wellbore stability and lost circulation
