... production rate. This rapid decline in the stimulation effect led to studies of gelled fluids, breakers, and propping agents that continue to this day. It is generally accepted that propping agents maintain fracture width and provide fracture conductivity to the well. These agents should be strong enough...

In all cases, the initial analyses documented that increasing conductivity appeared to increase production and recovery. By revisiting these case studies using extended production data, a more rigorous determination...
