HSE in Workover and Drilling Operations
This course is designed for
- Drilling engineers and drilling supervisors
- Completion engineers
- Production staff
- Petroleum engineers
- Other technical staff that need a practical understanding and an appreciation of HSE aspects of well drilling, completion, work-over and well intervention.
Learning Objectives
The course explains how drilling and completion operations are planned and executed to meet all HSE objectives, maximize well productivity, and cater for future work over and intervention needs. HSE concepts and methods are presented together with down-hole equipment, tools and their selection criteria. On course completion, participants will be able to:
- Apply the latest HSE protective measures in drilling operations, well completion, well stimulation, work over and intervention
- Recognize tubing pressure losses of different rock & fluid properties and corrosion/erosion potential
- Correctly set and operate casings, tubing’s and well head equipment
- Identify and consider wellbore, casing, tubing and packer issues on vertical, horizontal, and multilateral completions
- Discuss well integrity and HSE risks associated with perforation of oil and gas wells, including fishing, stimulation, fracturing, well testing and wire-line operations.
