Abstract: A method including providing sensors in injection and observation wells; increasing pressure within the injection well until a fracture extends from an initiation location through a portion of a subterranean formation to an intersection location in the observation well, wherein increasing pressure within the injection well comprises introducing fluid into the injection well; obtaining a measurement indicative of fracture initiation from the first sensor; determining a height of the fracture at the injection well; obtaining a measurement indicative of fracture intersection from the second sensor; determining a volume of fluid introduced between the fracture initiation and the fracture intersection; determining a distance between the initiation location and the intersection location; determining a time lapse between the fracture initiation and the fracture intersection; and using the determined values, calculating a hydraulic fracturing characteristic.

Abstract: A method of stimulating a subterranean formation is provided. The method includes determining a final fracture spacing. The method includes creating a first set of fractures at a first fracture spacing, the first fracture spacing being larger than the final fracture spacing. The method includes allowing production of fluids from the formation through the well bore via the first set of fractures for a period of time. The method includes, after the period of time, creating a second set of fractures. The final fracture spacing is less than or equal to an average fracture spacing between the first set of fractures and the second set of fractures.
