Third EAGE Integrated Reservoir Modelling Conference

The S/OBM DIF and filtrate may cause near-wellbore damage that prevents the reservoir from producing to its maximum potential. Traditional remediation chemical methods using surfactants, organic solvents, mutual solvents, and acid treatments are often ineffective, even after multiple treatments. A system based on novel Mesophase technology has been developed that effectively resolves this persistent problem. The paper describes a case of a well had experienced production declination over a number of years and did not improve even after several work over operations and after installing new ESP and production declined to less than 900 bopd. The objective was to treat the reservoir damage without changing the ESP. The Mesophase technology has been applied and proven to be remarkably effective in removing blockage from emulsions, water blockage, migrated solids and organic deposition solid migrates. After treatment, the ESP pressure intake was stable @ 470 psi, pump is working efficiently and production went from 900 bopd to an average of 1200 bopd. The Mesophase treatment fluids has been pumped and injected into the reservoir by bull-heading from the surface through the production tubing and ESP which saved the cost of changing the ESP and rig time
