There are now 18 operational wells in the MH field, an onshore oil field. The MH Field has to be developed because annual production there has dropped. Evaluation is one of the many factors that must be taken into account prior to improving production based on a production network system. The process of evaluating the MH field involves digitizing data into petroleum software. This work aims to assess the MH field prior to optimization. With the purpose of detecting issues in the MH Field and creating scenarios to boost production rates there, this assessment research was conducted at the MH Field with the use of petroleum software. To ensure that the simulation results accurately reflect the real field conditions, the first step in creating a pipe flow simulation is to characterize the actual field conditions. This demonstrates that the simulation results can be utilized as a reference for real data after simulating pipe flow in the MH Field with a variation factor less than 10%. The flow rate simulation's average variance was 0.40%, while the wellhead pressure simulation's divergence was 2.13%. These are excellent results from the MH field evaluation simulation. The MH research yielded satisfactory results, and in order to boost production rates, production optimization work needs to be continued.
