COURSE OVERVIEW

This practical and highly-interactive course includes real-life case studies and exercises where participants will be engaged in a series of interactive small groups and class workshops. 

 

Once a well has been drilled to total depth, it must be decided whether it can be made to produce oil and gas in profitable amounts. Perhaps only one out of six wells drilled can ever produce enough petroleum to recover costs and offer profit. Even then, that one well must be completed properly. Recompletion costs are high, and a bad completion may ruin a well. Completion must be done right the first time. 

 

During the field life cycle, some reservoirs undergo some physical and chemical changes. This leads to loss of revenue as the wells are no longer operating at their optimal conditions. Hence, workover and well intervention practices are required to safely and efficiently restore the wells back to production. 

 

This course is designed to provide participants with up-to-date overview of completions and workovers. It covers the types and objective of completion operations according to reservoir and production data; the natural flow and artificial lift including single, dual gas lift, ESP well completion; the completion equipment and completion fluid, pressure test function; the tubing specification as thread, grade, weight and material; and the use of API designing and material selection for sweet and sour gas. 

Further, the course will also discuss the equipment and tender document; the ability to design, plan, execute open hole and cased hole completion and prepare well program; the logistic and service companies; the ability to run completion string on site according to sequence of well procedure and HSE; the operational steps in the completion program; the main factors influencing completion design; the head valves types and applications; the overall approach to a well’s flow capacity and recognize major types of completion configurations; the main phases in completion and considerations, drilling and casing the pay zone; and the cement job, perforating and treating the pay zone. 

 

During this interactive course, participants will learn the special case of horizontal wells, production wellhead and production string or tubing; the packers, downhole equipment, subsurface safety valves, running procedure, artificial lift pumping and gas lift; artificial lift process and completion management artificial lift operations in open and cased holes; the main types of well servicing and workover, light well servicing, heavy servicing and workover operations on live wells and servicing and workover operations on killed wells; the deviated, multiple zone, subsea, horizontal, multilateral and HPHT completion; and the well stimulation, hydraulic fracturing and acid stimulation.
