The main aim of Reservoir Engineering is to optimize the field in terms of optimum profit. Reservoir engineers are the professionals who estimate the potential size of the reservoir in order to determine how much oil and gas is available, identify and define individual reservoirs and their physical properties, deduce each reservoir’s performance and consider all important economic factors.
Based on their calculations, they decide how to maximize the return on investment and operational efficiency. To be successful at this, reservoir engineers work with other experts such as geologists, geo-hydrologists and geosystems engineers to accurately determine where the oil and gas reserves are located using the laws of physics and chemistry because subsurface fluids cannot be physically viewed.
