Problem Well Analysis – Workovers and Interventions
An In-Person Training Course by Esanda.
In-House sessions are available upon request.
In today’s low oil price climate, more and more operators decide to work on existing producing wells rather than drill expensive new wells. At this course, participants will come away with an understanding of the significant decision areas in well workovers and interventions. Particular emphasis is given to well diagnosis, water control, acidizing, squeeze cementing, wireline techniques, concentric tubing, perforating, well control, and completion fluids.
- Identify and Select Problem Wells
- Prepare proposals for workovers/interventions
- Prepare work AFE and Budget
- Select proper kill fluids
- Know about unloading techniques with examples
- Use logging tools to identify well problems
- Understand the use and functions of coiled tubing, snubbing unit, and wireline
- Prepare programs and well diagrams
- Evaluate and compare mechanical or chemical interventions
- Decide and prepare for Plug and Abandonment
The Course Is Designed For:
- Completion engineers
- Production engineers
- Reservoir engineers
- Drilling engineers
- Field supervisors
- Production foremen
- Engineering technicians
Vlassis was born in Cairo Egypt where he studied at the Greek High School, followed by University studies in England to Masters Level in Engineering. His Initial training and career started in the Middle East followed by a return to Greece to become part of a multinational team for the development of the newly discovered Prinos field. Vlassis has recently returned to Cairo to set up a new oil company.
Vlassis has almost 40 years’ experience in the oil and gas industry with key areas being as follows
Over 30 years of preparing and implementing Workover, Completion, and Testing programs for single, dual, permanent, retrievable production and injection systems, combined with ESP’s or Gas lift. This experience starts from well killing procedures to final production testing and optimization of well performance. Most work performed offshore, in a high H2S environment.
