Abstract: The oil and gas production system requires energy in the form of pressure, and the choke plays an important role in controlling the flow rate. In this work, Nodal Analysis method was used to optimize oil production using bean size selection for two wells B40 and B50, respectively. PIPESIM was used to build the models for the two wells using the test production data acquired. For well B40, when there is bean-up from 0.2” to 0.8”, flow rate increases from 363.957STB/D to 2132.306STB/D at bottomhole and 359.535STB/D to 1890.4 71STB/D at wellhead nodes, respectively. For well B50, when there is bean-up from 0.2” to 0.8”, flow rate increases from 195.648STB/D to 4464.972STB/D at bottomhole and 500.005STB/D to 3870.941STB/D at wellhead nodes, respectively. This is evident in the plots whereby the operating point shifts repeatedly to the right as the bean size is increased successively. Finally, at the end of the study, the bean size for well B40 was re-selected from 0.25” (1/4) at a flow rate of 605.171STB/D to 0.28” (17.92/64) at a flow rate of 728.019STB/D. Similarly, for well B50, the initial bean size prior to optimization was 0.4” (25.6/64) and the flow rate was 1962.357STB/D. However, a bean-up to 0.5” (1/2) produced at a flow rate of 2882.492STB/D thus production optimization is achieved.
