Abstract: A system and process are provided for recovering petroleum from a formation. An oil recovery formulation comprising at least 75 mol % dimethyl sulfide that is first contact miscible with a liquid petroleum composition is introduced into a petroleum bearing formation, an oil immiscible formulation is introduced into the formation subsequent to introduction of the oil recovery formulation into the formation, and petroleum is produced from the formation.
Abstract translation: 提供了用于从地层回收石油的系统和方法。 将含有至少75摩尔％的与液体石油组合物可混溶的二甲基硫化物的油回收制剂引入含石油的地层中，在将油回收制剂引入地层之后，将油不混溶的制剂引入地层 ，石油从地层中产生。
