| Abstract | Numerical simulators were developed for students projects in Kyushu University. On the basis of the line source solution, numerical simulator for determining optimal values of transmissivity and storativity was developed on Excel by using Solver function. Input data of pressure transient, flowrate of active wells are input on Excel sheet. Numerical simulator for wellbore flow can be used for pressure and temperature profiles by giving wellhead condition such as pressure, steam and water flow rates, and well specification. Production well deliverability can also be simulated by coupling wellbore flow and reservoir flow under steady state. |
