Abstract: A process for producing gaseous hydrocarbon from a subterranean formation by hydraulically fracturing with injection of a liquid material under pressure such that a connecting fracture is generated extending between a lower injection well and an upper production well, where a gas-liquid interface is defined within the fracture or within the upper producing well, and producing gas across the gas-liquid interface.

Abstract: There is provided a process of stimulating a subterranean formation via a wellbore fluid passage of a cased wellbore. The process includes, with a perforating gun, perforating at least casing to form at least one or more perforations effecting fluid communication, via the wellbore fluid passage, between a first zone of the subterranean formation and a treatment fluid source. Treatment fluid is then injected via the wellbore fluid passage, from the treatment fluid source to the first zone such that fracturing of the first zone is effected. The injecting of the treatment fluid is then suspended. A perforating gun is then deployed within the wellbore fluid passage via wireline. The casing is then perforated to form at least one or more perforations effecting fluid communication, via the wellbore fluid passage, between a second zone of the subterranean formation and the treatment fluid source.

Abstract: There is provided processes for producing gaseous hydrocarbon material from a subterranean formation. A process includes hydraulically fracturing the subterranean formation such that a connecting fracture is generated that extends from a lower well to an upper well, and such that gaseous hydrocarbon material is received within the connecting fracture in response to the hydraulic fracturing. Another process includes stimulating the subterranean formation, when the formation already includes the connecting fracture extending from a lower well to an upper well, such that gaseous hydrocarbon material is received within the connecting fracture in response to the stimulating.

Abstract: A method of recovering product from a fracture below a surface, said method including: a. providing a first well that may be stimulated or has been stimulated at a first predetermined depth within a formation; b. stimulating said well resulting in at least one fracture in said formation; said fracture having at least one initiation point and at least one distal point; wherein said at least one initiation point is proximate said stimulated well and said at least one distal point is distant said stimulated well; c. providing at least one non-stimulated well, proximate said first well at a second predetermined depth in said formation and contacting said at least one distal point of said at least one fracture; said at least one non-stimulated well further including at least one access point to capture product from said at least one fracture in said formation; capturing said product from said fracture through said at least non-stimulated well, and recovering said captured product optionally at said surface.

Abstract: A method of stimulating an interval in a hydrocarbon reservoir equipped with a deviated wellbore having a casing, wherein said interval comprises at least two sequential stages in said wellbore without isolation means, said method comprising: i) introducing a first stage ii) introducing a second stage in the same wellbore wherein said first stage, and second stage are not separated by any isolation means; and optionally iii) recovering hydrocarbon from said hydrocarbon reservoir to a surface.

Abstract: The present invention relates to methods and compositions for treating subterranean well formations, and more specifically, to improved subterranean formation treating fluid concentrates, treating fluids and methods of using such treating fluids in subterranean formations. The treating fluid concentrates generally comprise water and a substantially fully hydrated depolymerized polymer. The treating fluids which are formed by adding water to the treating fluid concentrates generally comprise water, a substantially fully hydrated depolymerized polymer and a crosslinking agent for crosslinking the hydrated depolymerized polymer.
