Abstract

Most of the studies assumed that the amount of oil extracted with the primary drive mechanisms is about 20-30% and through secondary recovery can reach up to 40%. But using the modern Enhanced Oil Recovery (EOR) techniques, we can reach up to 60-65% of residual oil. These techniques are applied to mature and depleted reservoirs for improving efficiency compared to primary and secondary recovery. Radial drilling can be applied in the reservoir before any tertiary recovery process i.e., EOR which use high-cost exotic fluid to prolong the life of a field. By this radial drilling, it is easy to extract the production. Radial Drilling is a technique that utilises hydraulic jet energy of the fluid to drill lateral holes inside the reservoir. In these several small diameters,
holes are drilled from a mother well which radiates in different direction levels throughout the depth of the well or wherever there is a possibility of finding more oil and gas. It is mainly used to stimulate depleted or dead wells by bypassing the damaged/ skin zone and extracted crude from unreached virgin lateral holes extracted beyond the skin region.
