摘要： The present invention is directed to a method of hydrocarbon production from a hydrocarbon reservoir. The method includes providing a substantially horizontal wellbore having at least one productive interval within a hydrocarbon reservoir and forming at least one non- conductive transverse fracture in the reservoir along the substantially horizontal wellbore. An injection well is also provided. A fluid is injected into the reservoir through the injection well to displace hydrocarbons within the reservoir toward a production portion of the substantially horizontal wellbore. Hydrocarbons are drained from the reservoir into at least one production interval of the substantially horizontal wellbore. Fluid production from the at least one production interval into the substantially horizontal wellbore flows through an inflow control device that can restrict the fluid flow. A non-conductive transverse fracture can form a barrier within the reservoir to divert injected fluids to increase sweep efficiency and reduce the influx of injected fluids into the production interval.

摘要： Method of arranging proppant in a fracture of a subterranean formation are disclosed. The methods can include (a) introducing a first fluid blend through a wellbore and into the fracture to form a first proppant bank in the fracture, and (b) introducing a second fluid blend through the wellbore and into the fracture to form a second proppant bank in the fracture, wherein a viscosity of the first fluid blend is less than a viscosity of the second fluid blend. The flow of the fluids can be alternated or switched between a lower viscosity fluid blend(s) and a higher viscosity fluid blend(s), without stopping a flow of fluid to the fracture.
