Cost effective design of scale inhibitor squeeze treatments using a mathematical model
- Saudi Aramco, Dhahran (Saudi Arabia)
Scale formation and deposition in production facilities is a challenging problem faced by the oil industry. Their deposition leads to operational problems, safety hazards and an overall decrease in production efficiency. Downhole scale inhibitor squeeze treatments provide the most common and effective means of preventing the formation of oilfield scale deposits. This paper presents an analysis and design study of field inhibitor squeeze treatments. A mathematical model was used to simulate inhibitor squeeze return data from several Saudi Aramco wells. A wide range of sensitivities in squeeze treatments were investigated including inhibitor concentration, inhibitor volume, overflush size, shut-in time, etc. An optimization of the squeeze injection parameters was carried out using the numerical simulator. This optimization was based on squeeze performance as well as on economic criteria. The results indicate that the optimized treatment strategy is very well specific and depends on the water production rates, and operational parameters like the scale inhibitor concentration and volume and the amount of overflush. Recommendations are made for optimizing (in terms of cost effectiveness) the squeeze treatment design.
