A method for sweeping a subterranean petroleum reservoir and recoveringhydrocarbons therefrom. Such method utilizes a plurality of spaced hydraulicfractures extending radially outwardly from, and spaced laterally along, alength ofa single horizontal wellbore drilled through the reservoir. The hydraulicfracturesare each in fluid communication with the drilled wellbore. A multi-channeltubinghaving a plurality of individual discrete channels therein extending alongsubstantially a length thereof is placed in the horizontal wellbore, and atleast onepacker element situated along a length of said tubing is employed. Theplurality ofchannels in the multi-channel tubing comprise, at a minimum, a fluid injectionchannel for transmitting a driving fluid to hydraulic fractures in thereservoir, and aseparate hydrocarbon recovery channel for collecting hydrocarbons which draininto the reservoir and producing them to surface.
