Abstract
A pressure wave is generated within a first well extending into a subterranean formation. A pressure response associated with the pressure wave is detected from a second well extending into the formation. Information is then determined, based on the pressure response in the second well, wherein the information is associated with at least one of the formation and a fracture connected to at least one of the first well and the second well.
Claims25
A method, comprising:
- performing a first fracturing operation in a first well, wherein the fracturing operation generates a pressure wave within the first well extending into a subterranean formation;
- receiving a pressure response associated with the pressure wave in a second well extending into the subterranean formation, wherein measured parameters of the pressure response include a delay in an arrival time of the pressure wave at the second well, an amplitude of the pressure wave at the second well, and a period of the pressure wave at the second well;
- receiving an additional pressure response associated with the pressure wave in a third well extending into the subterranean formation;
- determining, based on the measured parameters of the pressure response in the second well, information associated with at least one of:
- the subterranean formation,
- or a fracture connected to:
- the first well, or
- the second well;
- determining, based on the information derived from the measured parameters of the pressure response in the second well, a quantity of diversion materials for a second fracturing operation that minimizes a respective pressure response associated with an additional pressure wave that would be generated by the second fracturing operation in the first well;
- and
- performing the second fracturing operation in the first well based on the determined quantity of the diversion materials.
