摘要： A method for enhancing hydrocarbon recovery in low permeability reservoirs comprises first providing a subterranean reservoir comprising one or more hydrocarbons and water therewithin and a wellbore in fluid communication with the subterranean reservoir. Next, a substantially anhydrous composition is injected into the reservoir through the wellbore. The substantially anhydrous composition comprises carbon dioxide and one or more surfactants. The composition is suitable to form a foam upon contact with the water within the reservoir. The method often results in reduced wellbore corrosion and hydrate formation, reduced reservoir fingering, and enhanced carbon dioxide sweep efficiency over conventional methods

摘要： Computer-implemented systems and methods are provided for optimizing hydrocarbon recovery from subsurface formations, including subsurface formations having bottom water or edgewater. A system and method can be configured to receive data indicative of by-pass oil areas in the subsurface formation from reservoir simulation, identify flow barriers in the subsurface formation based on the by-pass oil areas identified by the reservoir simulation, and predict the lateral extension of the identified flow barriers in the subsurface formation. Infill horizontal wells can be placed at areas of the subsurface formation relative to the flow barriers such that production from a horizontal well in the subsurface formation optimizes hydrocarbon recovery.
摘要翻译：提供计算机实施的系统和方法用于优化来自地下地层的烃采收，包括具有底水或边水的地下地层。系统和方法可以被配置为从储层模拟接收指示地下地层中的旁路油区的数据，基于由储层模拟识别的旁路油区来识别地下地层中的流动障碍，并且预测侧向在地下地层中确定流动屏障的延伸。可以将填充水平井放置在相对于流动屏障的地下地层区域中，使得地下地层中水平井的产量优化烃采收率。
