Completion design considerations
This article describes the Completion design considerations.
Reservoir drive mechanism may determine whether or not the completion interval will have to be adjusted as gas-oil or water-oil contacts move. A water drive situation may indicate water production problems. Dissolved gas drive will result in pressure depletion and may indicate artificial lift. Dissolved gas and gas drive reservoirs usually mean declining productivity index and increasing gas-oil ratio.
Secondary recovery needs may require a completion method conducive to selective injection or production. Water flooding may increase volumes of fluid . . .
