Claim 0:
1. A method of modeling fluid depletion from an unconventional reservoir, comprising:
measuring, via two or more gauges, a tubing head pressure of two or more wells penetrating at least a portion of the unconventional reservoir;
for the two or more wells, determining a bottomhole pressure for the unconventional reservoir based on the tubing head pressure of the two or more wells, one or more fluid properties of a fluid in the unconventional reservoir, and a well production volume for the two or more wells;
for the two or more wells, determining a drainage volume and a reservoir pressure depletion based, at least in part, on the bottomhole pressure for the unconventional reservoir;
for the two or more wells, determining, using an optimization routine, a transient well performance for the unconventional reservoir based, at least in part, on the drainage volume and the reservoir pressure depletion;
determining a Productivity Index (PI) for the unconventional reservoir, based, at least in part, on the transient well performance, the one or more fluid properties and measured well data for the two or more wells, wherein the measured well data comprises one or more of a well production rate and a well flowing pressure; and
identifying at least one well of the two or more wells experiencing production interference from another well based, at least in part, on the PI.
