However, it is reasonable to assume that length of lateral, stage spacing, type of fluid, proppant amount, rate of pumping...

... Abstract Many stimulated shale gas wells experience surprisingly low fracturing fluid recoveries. Fracture closure, gravity segregation, fracture tortuosity, proppant distribution, and shut-in (soaking) time have been widely postulated to be the contributing factors. This study examines...
