Experimental study on the discharge coefficient of perforation behaviours during hydraulic fracturing treatments
Hydraulic fracturing treatments are a significant stimulation technique for unconventional oil and gas reservoirs. The limited-entry technique is one of the most commonly used techniques for fluid diversion during hydraulic fracturing. This technique depends on the perforation pressure drop to achieve uniform injection profiles. The perforation pressure drop is influenced by many factors, such as flow rate, proppant concentration and fluid viscosity. The discharge coefficient (C_d) can also affect the perforation pressure drop. This research provides an understanding into the influence of various ...
