Consider 1D porous medium (discretize to three uniform grid blocks each of AXZ200 , AYZIOO ft, A2240 ft), the boundary condition is no ow boundary. The Viscosity is 2 cp, Ct:3"'10'6 psi-l, PHI:12%, At:10 days, the well is in second grid-block, Pi:2400 psi K: 60 md. the well produce at rate of 450 STE/day, determine pressure distribution for two time steps, If the dimensions of grids are doubled, what is the pressure distribution
