Abstract:
Techniques for determining a proppant-area of a hydraulic fracture include identifying a fracture fluid leak-off curve that includes time-dependent pressure signal values of a first fracturing fluid in a monitor wellbore that is in fluid communication with a first hydraulic fracture formed from the monitor wellbore. Each of the time-dependent pressure signal values is a pressure change in the first fracturing fluid induced by a second hydraulic fracture from a treatment wellbore formed by a second fracturing fluid that includes proppant. The techniques further include determining a time value corresponding to a time-dependent pressure signal value associated with proppant landing time in the second hydraulic fracture; generating a pre-closure curve that includes extrapolated time-dependent pressure signal values; determining an intersection of the fracture fluid leak-off curve and the generated at least one pre-closure curve; determining a time-dependent pressure signal value that occurs at the intersection; and determining a proppant-area dimension of the second hydraulic fracture.

Claim (Index 16):
A computer-implemented method for determining a proppant-area of a hydraulic fracture, comprising:\n identifying a fracture fluid leak-off curve that comprises a plurality of time-dependent pressure signal values of a first fracturing fluid in a monitor wellbore formed from a terranean surface into a subsurface formation, the first fracturing fluid in direct fluid communication with a first hydraulic fracture formed from the monitor wellbore into the subsurface formation, each of the plurality of time-dependent pressure signal values comprising a pressure change in the first fracturing fluid that is induced by formation of a second hydraulic fracture from a treatment wellbore in the subsurface formation, the second hydraulic fracture formed by a second fracturing fluid in the treatment wellbore, the second fracturing fluid comprising proppant; determining a time value corresponding to one of the plurality of time-dependent pressure signal values, the time value associated with proppant landing time in the second hydraulic fracture; back-extrapolating from the determined time value to generate at least one pre-closure curve that comprises a plurality of extrapolated time-dependent pressure signal values; determining an intersection of the fracture fluid leak-off curve and the generated at least one pre-closure curve; determining a particular time-dependent pressure signal value of the plurality of time-dependent pressure signal values of the fracture leak-off curve that occurs at the intersection; based on the determined particular time-dependent pressure signal value, determining a proppant-area dimension of the second hydraulic fracture formed from the treatment wellbore; and determining the proppant-area of the second hydraulic fracture based on the determined proppant-area dimension of the second hydraulic fracture.
