Predictive Model for Compressive Strength of Epoxy Sand Consolidation System for Oil Wells

Solomon Adjei Marfo

Abstract


Compressive strength is a critical parameter for the success of chemical sand consolidation operations in oil wells. Predicting the right compressive strength is affected by factors such as curing time, bottomhole temperature, pore volume treatment and active clay concentration of the formation. The ability to model and optimise these factors is therefore crucial in obtaining the desired compressive strength required to stop fines migration in hydrocarbon production without excessive reduction in permeability. This paper thus aimed at studying the main and interactive effects of curing time and temperature on the compressive strength of an epoxy sand consolidation system. Based on the results obtained and with the aid of statistical analysis software, a predictive model and calculator were developed for predicting the compressive strength for epoxy chemical sand consolidation system. The results revealed significant impacts of the curing time and the temperature on the compressive strength of the epoxy system, though the interactive effects of these two factors did not have significant effect on the compressive strength. The compressive strength model developed could be used to explain about 97 % of the variability in the model, affirming an effective model. The software developed could be useful in laboratory and field applications, while the predictive model could be employed as optimisation tool for designing epoxy chemical sand consolidation operations in the oil and gas industry.
