Well completion and workover. Part 7. Considerations for selecting well servicing fluids

Part 7 in the H.K. van Poollen and Associates Inc. series discusses key considerations and presents general guide charts to aid in the selection of a well-servicing fluid. The primary consideration is to use the most readily available, cheap, easy-to-handle fluid that satisfies all the objectives for the completion or workover. Engineers selecting a well-servicing fluid must consider the possible formation damage caused by the fluid's interaction with the rock and the reservoir fluids.
