Drilling and Completion Chemicals in the Oil Course
Introduction:
Drilling operations are conducted subsequent to the initial completion to restore commercial production or injection, address mechanical issues in the well, or permanently seal and abandon the well. Work-over operations are typically initiated when hydrocarbon production rates significantly decline. The undesirable production of fluids may arise due to inadequate primary cementing or water/gas coning. These work-overs commonly involve remedial cementing to control the undesired water/gas production.
Well completion procedures take place once drilling operations are finished to establish the initial production or injection from the well. The specific completion methods employed can vary based on the type of completion and the geographical location. For instance, in flowing wells, the process may involve perforating the well and commencing production. In areas with low reservoir pressure, artificial lift mechanisms such as rod or submersible pumps, gas lift valves, and others may be necessary to achieve economically viable production rates.
