Abstract: A process of recovering oil from an oil-bearing formation which process comprises injecting a surfactant containing enhanced oil recovery formulation into the formation via an injection well and recovering oil and optionally gas via a recovery well which process comprises determining the apparent viscosity of the enhanced oil recovery formulation at various ratios of enhanced oil recovery formulation to oil wherein the highest apparent viscosity is at most 4 times the lowest apparent viscosity measured.

Abstract: A method and a system for producing petroleum from a formation utilizing a sacrificial agent and a surfactant are provided. The sacrificial agent reduces the amount of surfactant required to enhance oil recovery from a petroleum-bearing formation. The sacrificial agent is provided in a oil recovery formulation comprising a sacrificial agent and a surfactant dispersed in a fluid. The sacrificial agent is selected from the group consisting of a compound comprising a single carboxylic acid, a single carboxylic acid derivative, or a single carboxylate salt, or a compound lacking a carboxylic acid group, a carboxylate group, a sulfonic acid group, or a sulfonate group that is a pheol, a sulphonamide, or a thiol, or a compound having a molecular weight of 1000 or less that comprises one or more hydroxyl groups. The oil recovery formulation is introduced into a petroleum-bearing formation and petroleum is produced therefrom.

Abstract: A process for recovering oil from an oil-bearing formation is provided. A first oil recovery fluid is introduced into a formation through a first well for a first time period and oil is produced from a second well. A second oil recovery fluid different from the first oil recovery fluid is introduced into the formation through the second well for a second time period after the first time period, and oil is produced from a third well, where the second well is located on a fluid flow path extending between the first and third wells.
Abstract translation: 提供了一种从含油地层回收油的方法。 第一油回收流体通过第一井第一次引入地层，并且从第二井产生油。 与第一油回收流体不同的第二油回收流体在第一时间段之后的第二时间段内通过第二井引入地层，并且从第三井产生油，其中第二井位于流体 在第一和第三井之间延伸的流动路径。
