Pressure Changes While Fracturing Add To Marcellus Well Production

When it comes to hydraulic fracturing, steadiness may not be a virtue. That was the conclusion of a test to see if rapid pump rate variations would lead to greater production than conventionally fractured stages when the pressure was held steady.

The stages in which rapid pump variations were used to create pressure pulses produced an average of 18% more gas than the ones with steady pumping pressure, said Jordan Ciezobka, manager of research and development for the Gas Technology Institute (GTI), which did the test in the Marcellus with WPX Energy. The project was funded by the Research Partnership to Secure Energy for America (RPSEA).

Based on early results, this simple method may “increase production with no change in the water or sand pumped,” he said during a presentation at the recent SPE Hydraulic Fracturing Technology Conference.
