Abstract:
A method of drilling and stimulating subterranean formations is provided that allows a well operator to determine in real time if a fracture treatment has been successful, and whether the fracture treatment composition is sufficient for subsequent fracking. The method involves placing fracture treatments into a wellbore while the drilling operation is still under way. The fracture treatment is bounded in the open hole on one side by the current end of the hole and on the other side by a temporary pack off isolation fluid that has been introduced to the well by way of pumping down the existing drill string or by pumping down a separate frac string. The objective is to place the frac in the reservoir and flow it back very quickly after placement, thus increasing the chances of flowing back harmful formation damaging materials and increasing the relative productivity of the newly placed fracture treatment.
