Abstract: Some systems and methods include a tubular defining a passageway, one or more packers coupled to the tubular, and two or more valves coupled to the tubular. Some such systems are operable by increasing pressure within the passageway such that, responsive to the increasing pressure, one or more first ones of the valves open and fluid flows from the passageway, through the first valve(s), and into one or more first fractures of the wellbore, and reducing pressure within the passageway such that, responsive to the reducing pressure, the first valve(s) close and one or more second ones of the valves open and hydrocarbons flow from one or more second fractures of the wellbore, through the second valve(s), and into the passageway. The first and second valves can be unidirectional valves.

Abstract: Some methods of producing hydrocarbons from a formation include pressurizing a formation by pumping fluid into a portion of a wellbore having one or more first fractures in fluid communication with the formation, while the formation is pressurized, restricting fluid communication between the formation and the wellbore via the first fracture(s), and, while fluid communication between the formation and the wellbore via the first fracture(s) is restricted, producing hydrocarbons from the formation via one or more second fractures of the wellbore that are in fluid communication with the formation. Some methods include, while fluid communication between the formation and the wellbore via the first fracture(s) is restricted, creating the second fracture(s).

Abstract: Some methods of production hydrocarbons from a formation comprise drilling two or more horizontal wellbores in the formation, at least a portion of each extending in a direction that is within 20 degrees of parallel to a direction of maximum horizontal stress of the formation. The horizontal wellbores can include one or more producer wellbores and one or more injector wellbores, each of the producer wellbore(s) separated from at least one of the injector wellbore(s) by a formation-permeability-dependent well spacing. Some comprise comprising creating one or more longitudinal fractures that are in communication with the formation in each of the horizontal wellbores, injecting a recovery fluid comprising gas into at least one of the injector wellbore(s) such that the recovery fluid flows into the formation, and receiving hydrocarbons from the formation into at least one of the producer wellbore(s).
