Analysis on parameters involved in 2-D fracture geometry design

During past decades, the depletion of oil and gas reservoirs and increasing of the hydrocarbon price, major companies in oil and gas industry endeavor to enhance the recovery of hydrocarbon from the present reservoirs as well as marginal reservoirs. One of the most successful ways to improve oil and...
