Reservoir simulation is a common practice in EOR through fluid injection into reservoir. Reservoir simulation acts as a tool to monitor the movement and flow of reservoir fluid as well as injection fluid. Fluid replacement from water to oil, in a two-phase reservoir system, is inevitable as water will push oil to producing wells. These two substances have different density, thus it will allow a change in reservoir fluid density (&#916;&#961;) and gravity response (&#916;g). <br /> <br /> <br /> <br /> To allow countless and easy model making and parameter setting that commercial program hardly offer, a reservoir fluid flow simulation program was made by using MATLAB programming language with IMPES technique as general reference in the program developing process. <br /> <br /> <br /> <br /> One dimensional synthetic model was developed to test the program and it gave an RMS error of 32,914510%&#8722;×. Then, the program is applied to four 609,6 m x 609,6 m 2D models which differ in initial reservoir pressure and reservoir thickness.. A change of 0 – 0,039 gr/cc of reservoir bulk density gave 1,05 &#956;Gal and 0,69 &#956;Gal in maximum gravity response difference for 700 m and 1200 m of depth respectively. With a difference of 150 m in thickness, a gravity response difference of 1 &#956;Gal and 0,36 &#956;Gal for 700 m and 1200 m of depth respectively was observed. Then, with a difference of 500 m in depth, a maximum gravity response difference of 1,85 &#956;Gal was observed. Reservoir simulation can finally be developed as preliminary and complementing study to gravity survey to give general view about the change of gravity response in EOR activity.
