Reference to market demands and reduction of drilling hazards expenses, a well re-entry drilling technique was established. This technique requiring a combination of drilling & work over operation, starting from preparing present well for drilling operations as: killing present well, pulling existing completion string, running casing log for casing integrity, plug and abundant present bay zone and opening window in present casing either by several techniques such as whip-stock, milling window in casing, milling liner hanger & liner overlap plus enough open hole then side track and wells with angle higher than 70 degree and was completed as open hole till drilling and running completion of the new targeted well.
By the end of this training course, participants will learn to:
- LEARN the techniques to enhance of oil or gas recovery
- GAIN knowledge of how to build economical targets in company projects
- INCREASE the oil fields productivity
- GAIN the knowledge of how to meet the market demand
- SLOVE the workover hazards to avoid extra expenses and time
- LEARN the techniques of killing NPT and improving KPI during the operation
