Drilling and completion operations are crucial to the long term viability of the wells in meeting specified objectives and Workover operations are necessary when performance does not meet the planned expectations. The Well Design or Workover project covers the areas of well planning to provide optimum production and injection performance, the optimum well design to reach the specified target location ensuring safety, maximum integrity and reliability at minimal costs. This includes the selection of optimum well trajectories, equipment selection, drilling, completion and workover planning and scheduling, rig selection and cost estimate. When the project is to perform a well workover, the process will involve the selection of a new completion string, well cleaning, re-perforation of the formation or possible side-tracking and the use of stimulation techniques such as, Acidisation, acid and hydraulic fracturing and sand control operations.
