Evaluation of the Performance of Injection Wells in EX Structure

One of the efforts that can be done to evaluate performance water injection in a field is by monitoring injector wells. Observations made looking at flow rate and pressure each well. The response given well will able represent on scale. EX structure has been produced for more than 40 years. In addition, also applied approximately 16 There are four wells operating this with an average 3000-8000 bwipd per Evaluation carried out conducting Hall Plot from start process last data obtained. Based evaluation results, it was found there plugging EA-IIS EJ-IVS Stimulation activity needed both restore capability. Meanwhile, EA-IS EB-IIL wells, no significant problems those so they still function properly as
