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.
