Most oil and gas companies use numerous specialized service companies for wells workover and completion onshore and offshore. All service providers need to be coordinated, controlled and managed onsite by the company man (supervisor) to achieve highest efficiency and safety level of the operations. The supervisor usually is fully responsible for the operations, so the supervisor is the decision maker in case of emergency and the liaison with the office engineering support. Thus, the supervisor has to have understanding of all aspects of well completion, intervention and workover techniques, surface and downhole equipment; ability to plan ahead and good communication skills.
The course is designed for completion, well intervention and workover supervisors and engineers from service and operating companies.
- HSE requirements, best practices, risk assessment techniques for particular operations onsite and for the complete completion/workover process.
- Emergency response, immediate action on site after the incident has occurred for the incident subsequent incident investigation.
- Permit to work system, simultaneous operations offshore and onshore, effective safety briefings with crews; control, spot checks and audits of onsite activities.
- Planning of onsite activities for well completion and workover. Organizing logistic supply schemes for offshore and onshore locations. Control of movements of equipment and supplies.
- Main completion types of vertical and horizontal wells. Influence of the well completion type onto well productivity and skin factor.
- Well control during well completion, workover and intervention. Definition of “barrier” in the well.
- Well completion fluids.
- Tubing and downhole inspection prior running in hole. Completion and tubing running into the well. Basics of tubing design: influence of temperature and combination of loads onto tubing tensile and torsional limits. Types and characteristics of threaded connections.
- Fishing and remedial cementing.
- Wireline intervention: types, downhole and surface equipment (including well tractors).
- Slickline intervention: types, downhole and surface equipment.
- Coiltubing intervention: types, downhole and surface equipment.
- Methods of well inflow intensification: acidizing, hydraulic fracturing, etc.
- Sand control techniques and equipment: screens, gravel packing.
- Hydrates prevention and mitigation during well interventions.
- Main types of quick-connect surface threaded connection for control lines and temporary pumping lines.
- Wellhead equipment, X-mass trees, tubing hangers.
- Information collection and reporting to the engineering support.
