Surfactant-Assisted Spontaneous Imbibition to Improve Oil Recovery on the Eagle Ford and Wolfcamp Shale Oil Reservoir: Laboratory to Field Analysis

Abundant resources being left behind at the end of the short production life of an unconventional liquid-rich reservoir (ULR) well has inspired many to investigate methods to improve the recovery. One eminent method is through the addition of surfactant during the completion stage of the well. Through numerous published laboratory studies, it can be concluded that this process possesses a promising potential in improving overall well productivity. Several field-scale results gathered from public data sources also confirmed the laboratory-scale study by correlating the effect of surfactants to the improvement of the estimated ultimate recovery (EUR). However, the absence of independency on those field-scale results often casts doubt on the actual efficacy of the method. The lack of field-scale information in the realm of scientific publications contributes to the limited understanding of surfactant application. This study is to fulfill the obvious need of field-scale studies on the application of surfactan...
