Magnetized Water for Improve Sweep Efficiency

摘要

Mature oil and gas fields are difficult to rehabilitate effectively because of the economics and declining production. Many fields are abandoned prematurely when their life could be prolonged significantly through application of new technology. Based on this notion, mechanisms of petroleum recovery by magnetized water injection were taken into consideration. Advantages and disadvantages of its injection in the petroleum reservoirs have been reviewed and compared with water flooding. The magnetized water flooding result was remarkable when compared to ordinary water and saline water flooding result. During the course of the study, a mathematical model of the forces involved in magnetized water flooding was developed and the result of the model was validated in the laboratory experimentally. Based on the extensive studies it was observe that the laboratory result was in agreement with the mathematical model developed. From the result gotten, it is strongly convinced that the technique of using magnetized water to flood pressure depleted reservoirs hold promise in the future. If adequately applied can recover up to 45 – 60 percent of the total oil in place.
