Wellbore hydraulic fracturing through a pump operating in a damage avoidance mode

A method for conducting a hydraulic fracturing job in a subterranean formation using a pump, the method comprising:

• selecting a fluid pump of known operating pump capacity, wherein the operating pump capacity is measurable in barrels per minute;
• fluidly connecting the pump with a first cased wellbore and a second cased wellbore in a subterranean formation for providing pumped fracturing fluid concurrently to the first cased wellbore and the second cased wellbore;
• wherein each of the first cased wellbore and the second cased wellbore have at least one passage through a casing of the wellbore and each passage has a known rate range within which fracturing fluid is required to be provided to the passage to successfully fracture the subterranean formation outside the passage, through the passage;
• and
• wherein both the first cased wellbore and the second cased wellbore are configured so that the pump provides fracturing fluid to each of the passages within the known rate range of the respective passage to successfully fracture the subterranean formation outside the passage while operating the pump, during a pumping stage of the hydraulic fracturing job, in a damage avoidance mode and the damage avoidance mode is characterized by:
• operating the pump on a per passage cluster-basis to cause each passage in a cluster to concurrently receive fracturing fluid at a rate specific to operation in the damage avoidance mode;
• and
• providing fracturing fluid to the first cased wellbore and the second cased wellbore so that a passage cluster in the first cased wellbore and a passage cluster in the second cased wellbore concurrently receive fracturing fluid while operating the pump in the damage avoidance mode.

A system for conducting a hydraulic fracturing job in a subterranean formation using a pump, the system comprising:

• a fluid pump of known operating pump capacity, wherein the operating pump capacity is measurable in barrels per minute;
• one or more fluid couplings that fluidly connect the pump with a first cased wellbore and a second cased wellbore in a subterranean formation for providing pumped fracturing fluid concurrently to the first cased wellbore and the second cased wellbore;
• wherein each of the first cased wellbore and the second cased wellbore have at least one perforation through a casing of the wellbore and each perforation has a known rate range within which fracturing fluid is required to be provided to the perforation to successfully fracture the subterranean formation outside the perforation, through the perforation;
• and
• wherein both the first cased wellbore and the second cased wellbore are configured so that the pump provides fracturing fluid to each perforation within the known rate range of the respective perforation to successfully fracture the subterranean formation outside the perforation while operating the pump, during a pumping stage of the hydraulic fracturing job, in a damage avoidance mode and the damage avoidance mode is characterized by:
• operating the pump on a per perforation cluster-basis to cause each perforation in a cluster to concurrently receive fracturing fluid at a rate specific to operation in the damage avoidance mode;
• and
• providing fracturing fluid to the first cased wellbore and the second cased wellbore so that a perforation cluster in the first cased wellbore and a perforation cluster in the second cased wellbore concurrently receive fracturing fluid while operating the pump in the damage avoidance mode.
