Mitigating risk by using fracture mapping to alter formation fracturing process

Abstract From the Canadian patent

A formation fracturing method with which to mitigate risk to hydrocarbon productivity includes pumping fracturing fluid during at least part of a fracturing job time period into a well to fracture a formation; generating signals within the fracturing job time period, in response to at least one dimension of the fracture; and further pumping fracturing fluid within the fracturing job time period, into the well in response to the generated signals. Further pumping includes controlling at least one of a pump rate of the further pumping and a viscosity (either fluid viscosity or particulate concentration) of the further pumped fracturing fluid. Control can include comparing a measured magnitude …
