dc.description.abstractThe efficiency of water injectivity into the reservoir is greatly reduced by poor reservoir permeability and near well bore damage. However, the aim of this study is to evaluate the possibility of improving oil recovery during water flooding by using radial drilling technique which has the capacity of achieving longer perforation length than the conventional perforation operation. Perforation length up to 100 m (330ft) into the fresh formation beyond damaged zone can be obtained with radial technology. Eclipse simulator, version 100 was used to model the lateral radial drill and conventional perforation into there servoir. The key project indicators that were studied are injectivity index, displacement efficiency,recovery factor and water cut using different radial drill configurations. It was observed that water injectivity was improved with radial drill case with the increasing length and number of radials as compared to the conventional wellbore perforation case. There was aprogressive increase in recovery factor with increase in number radials irrespectiveoftheradial length. Also, the water cut from the producer well was increasing as the number and length of the radials were increasing. Therefore, radial drilling is seemingly apromising technology that can be used to improve water inj ectivity and hence maximize oil recovery in a water flooding scheme.
