A system and method for a conformance control treatment for a subterranean reservoir are disclosed. The system and method include performing tracer analysis between an injection well and a production well. A flow capacity and storage capacity curve is constructed from the tracer analysis. A storage capacity associated with a threshold residence time is determined using the flow capacity and storage capacity curve. A conformance control treatment is determined for the storage capacity associated with the threshold residence time. A chemical slug is injected into the injection well to increase the flow resistance in high permeability regions of a subterranean reservoir.

System and method for conformance control in a subterranean reservoir

A system and method for optimizing sweep efficiency of an enhanced oil recovery process in a subterranean reservoir is disclosed. The system and method include computing a displacement coefficient representative of heterogeneity of an unswept region in the subterranean. A functional relationship between operating conditions of one or more well control devices and the displacement coefficient is determined. The sweep efficiency of the enhanced oil recovery process can be optimized by adjusting the well control devices such that the displacement coefficient is minimized. Streamline simulation can be utilized to compute the displacement coefficient from the flow capacity and storage capacity of the unswept region in the subterranean reservoir.

System and method for enhancing oil recovery from a subterranean reservoir

A method is disclosed having application notably towards ranking earth models responsive to dynamic heterogeneity. A plurality of earth models representing a subsurface reservoir are provided. Streamline analysis for each of the plurality of earth models is conducted. Flow Capacity (F) vs. Storage Capacity (&#x3a6;) curves are constructed for each of the plurality of earth models based on the streamline analysis. Dynamic heterogeneity for each of the plurality of earth models is computed from the Flow Capacity (F) vs. Storage Capacity (&#x3a6;) curves constructed for each of the plurality of earth models. The plurality of earth models are ranked responsive to dynamic heterogeneity.
