Experimental Study on Rock Failure Patterns and Mechanisms of Hydraulic Frac-Packing in Weakly Consolidated Sandstone Reservoirs
Frac-packing is an integrated stimulation and sand-control technology widely used in weakly consolidated sandstone (WCS) reservoirs. However, frac-packing treatments in the Sebei Gas Field exhibit substantially higher proppant intake than conventionally expected. Typical frac-packing intensity in WCS reservoirs is ap...
