FORECASTING OIL PRODUCTION FOR MULTIPLY-FRACTURED HORIZONTAL WELLS

摘要

Methods, computing systems, and computer-readable media for forecasting oil recovery from a well. The method includes obtaining bottom-hole pressures, production rates, and a reservoir pressure for the well, and calculating pressure normalized rates based thereon. The method also includes forecasting a forecasted bottom-hole pressure for a first material balance time, based on the plurality of bottom-hole pressures, and forecasting a forecasted pressure normalized rate for the first material balance time based on the pressure normalized rates. The method further includes calculating a forecasted production rate for the first material balance time, based on the production rates, and determining a first forecasted cumulative production at the first material balance time based on the forecasted production rate, bottom-hole pressure, and pressure normalized rate, and converting the first material balance time to a first real time based at least partially on the forecasted cumulative production and production rate.
