Abstract

Experience in the oil industry has indicated that many oil wells have suffered flow restriction because of scale deposition within the oil producing formation through matrix and the down hole equipment.

Scale in oil field, just like the scale found in home plumbing or tea kettles, can be deposited all along water paths from injectors through the reservoir to surface equipment. Most scale found in oil fields forms either by direct precipitation from the water that occurs naturally in reservoir rocks, or because of produced water becomes over saturated with scale components when two incompatible waters meet down hole.

To tackle the effect of inorganic scale (Calcium Carbonate) on well productivity, three wells from Amal field namely B96, B20 and B72 have been included in this study. Most of the wells in Amal field, area B, were subjected to the same kind of in organic scale, and to the test of scale solubility, and all samples were successfully dissolved in HCL.

Prosper software as well performance tool was used to generate models of inflow and out flow curves before and after stimulation job was done to those wells. The results showed a significant increase in production
