Alpha Sand is a low permeability reservoir with high resistance for fluid flow. One of the methods to improve Alpha Sand production is by conducting a stimulation procedure. Five stage horizontal fracturing aims to increase the flow rate of oil from this low permeability reservoir specifically in the Alpha 1530 sand. The completion design was determined based on considerations for selective production/ Fracturing intervals and possibility of sand fill. Cement bonding and cement casing evaluation were conducted on the lateral section to ensure good cement isolation between each fracturing interval. Perforation Type was determined based on proppant that introduced to the sand formation. The Fracturing design also took into consideration that the direction of the fracture could not grow into/penetrates the water zone at the Delta 1600’ sand. The general result of this operation was an increase in oil production rate with low water cut. This result validated that the fractures were not penetrating water zone on Delta 1600’ sand. Generally, the operation is considered a success but it is suspected a higher number of optimized oil flow rate can be achieved if the well is put on production (POP) immediately.
