Abstract

This project entitled evaluation of polyaspartate for mitigating BaSO4 was to evaluate and test the efficiency of polyaspartate the green scale inhibitors to replace the conventional scale inhibitors in mitigating Barium Sulphate scale. Scale deposition is one of the most serious oil field problems that mainly come from water injection systems. The precipitation of these mineral scales can create a major cause of formation damage either in injection or producing wells, block production tubing, reduce the porosity and permeability of the reservoir and many more. Scale inhibitor was invented to overcome the problems. However, conventional scale inhibitor does not have biodegradable ability and the chemical may harm the marine environment if the discharge of the chemicals was being thrown into the sea. With respect to the oil industry, international environmental statutes and guidelines have decided to restrict the use and discharge of potentially toxic chemicals into the sea and by this requirement, it is important and urgent to replace the conventional scale inhibitor with more environmental friendly green inhibitor. Scope of study included in the detailed analysis on polyaspartate in mitigating BaSO4 scale, the green scale inhibitors in order to achieve the objectives stated above. The proposed methods for this project are by conducting Tube Blocking Test and Static Jar Test for both dynamic and static condition. Its objective is to evaluate the efficiency of chemical inhibitors to prevent the formation and deposition of sulphate scales. It was proven that from both of the test that were conducted, Polyaspartate can exhibit a competitive inhibiting efficiencies in sulphate scale formation.
