imestone reservoir is flowing in y direction with porosity and viscosity of the liquid v 21.5% and 25.1 cp respectively. The reservoir has been discretised into 5 mesh with so 1 located at mesh number 3 and sink well located at mesh number 1 and 5. The in ssure of the system is 5225.52 psia and the values of Dz, Dy and Dx are 813 ft, 831 ft 1 ft respectively. The liquid flow rate is held constant at 282.52 STB/day and meability of the reservoir in y direction is 122.8 mD. By assuming the reservoir is flow
