Claim 0:
1. A method for characterizing a subterranean formation during a hydraulic fracturing operation comprising:
a) injecting a fluid into an active well of the subterranean formation at a pressure sufficient to induce one or more hydraulic fractures;
b) measuring, via a pressure sensor, a poroelastic pressure response caused by the inducing of the one or more hydraulic fractures, wherein the pressure sensor is in at least partial hydraulic isolation with the one or more hydraulic fractures;
c) extracting one or more essential characteristics of said poroelastic pressure response;
d) identifying a pressure signature based on said one or more essential characteristics;
e) comparing the pressure signature to a database of pressure signatures to identify a match
wherein said database of pressure signatures is augmented with additional parameters for completion design selected from one or more of injection rate, fluid type, fluid volume, proppant type, proppant volume, cluster spacing, and stage spacing; and
f) interpreting the pressure signature in real-time to provide an immediate assessment of one or more hydraulic fracture dimensions.
