| Abstract | A pressure transient analysis method is presented for interference between wells producing at constant rate and wells producing at constant pressure. The wells are modeled as two line source wells in an infinite reservoir. The first well produces at a constant rate, and the second well remains at a constant pressure. Dimensionless semi log pressure type curves are presented together with instantaneous rates and cumulative dimensionless injection for the constant pressure well. The effects of the relative size of the two wells on the pressure response of the constant rate well and on the rate of injection at the constant pressure well are discussed. The rate pressure model may also be applied in analyzing pressure interference between communication geothermal reservoirs. The distance between the reservoirs may be estimated if the reservoirs are approximately as two line sources. |
