先前的实验研究和已发表的现场试验表明，注入表面活性剂可以成为提高采收率的有效手段。然而，大多数实验都是在环境条件而不是储层条件下进行的。整篇论文提出了一种在高压和高温下筛选热稳定表面活性剂的新方法，其明确目的是改变运营商 Eagle Ford 区域的润湿性。
表面活性剂的使用是在该剧一开始就开始使用的。经过大约 5 年的现场开发后，这些表面活性剂停止使用。
Previous experimental studies and published field trials have shown that injected surfactants can be an effective means of improving recovery. Most experiments, however, have been conducted at ambient rather than reservoir conditions. The complete paper presents a novel approach to screen thermally stable surfactants at high pressures and high temperatures for the explicit purpose of wettability alteration in the operator’s Eagle Ford acreage.
Surfactant usage was initiated at the inception of the play. The use of these surfactants was discontinued after approximately 5 years of field development.
