摘要： There is provided a method of producing hydrocarbon material. A first hydrocarbon material is produced from the formation, the first hydrocarbon material including a gaseous hydrocarbon material originally in place in the formation. At least a portion of the produced gaseous hydrocarbon material is injected into the formation to increase the formation pressure. A second hydrocarbon material is produced from the formation.

摘要： A method for capturing hydrocarbons from a formation is provided. After a first hydraulic fracturing of a formation to produce a first conditioned formation, and while hydrocarbons are being produced from the first conditioned formation, a predetermined wellbore characteristic is monitored for. The predetermined wellbore characteristic is based on at least a pressure within the first conditioned formation. After detecting the predetermined wellbore characteristic, a second hydraulic fracturing of the formation is effected to produce a second conditioned formation.
