Effects of Temperature on Silicate Scale Inhibition During ASP Flooding

A.A. Umar and I.M. Saaid

Abstract:
Alkaline/Surfactant/Polymer (ASP) flooding is a widely acceptable enhanced oil recovery technique. Despite its popularity as a potentially cost-effective chemical flooding method, it is not devoid of some problems, a major of which is the excessive formation of silicate scales. Silicate scale is a very serious problem in the oil and gas industry, which can form in perforation holes, casing surface, tubing and surface facilities. As the ASP flood progresses into the production well, produced liquid from different layers intermingle, there is decrease in pressure and temperature and there is rapid decrease in the pH of the mixed waters. These among other factors result to precipitation of silicates and its deposition on tubing, surface pipeline, pumps and surface production facilities, resulting into excessive production loss, increasing the average workover periods which influence the production and cause low commercial effectiveness. This study studied the effects of temperature on the performance of some scale inhibitors to mitigate silicate scales. Scale Inhibitors tested here are: RC1, RC7 and PASP. The study is part of an ongoing research on green scale inhibitors for mitigating silicate scales during ASP Flooding. Future publications will cover some proposed PGLU based green scale inhibitors.
