Abstract: To accurately estimate oil and gas reserves, plan for the development of the field, it requires a sound knowledge of engineers to adequately predict the performance of the reservoir since nobody can enter the reservoir to actually tell it content and behavior. It is therefore imperative to note that whatever result obtained from such prediction, must be within reasonable engineering tolerance of error. This implies that its success will depend solely on the accurate description of the reservoir rock properties, fluid properties, rock-fluid properties and flow performance. In the study, Tarner’s, Tracy’s and Schilthuis methods of reservoir performance prediction using material balance techniques was adopted to predict the performance of XY reservoir. Hence, after performing several iterations, the results obtained with Tracy’s and Schilthius’ methods indicate a closeness with the XY reservoir performance prediction at 2870 psia, which is an indication that either Tracy’s or Schilthuis method can be used to predict the XY reservoir performance at lower pressures as the reservoir declines.
Keywords: performance predictions, oil production, gas production, gas-oil ratio, reserves, material balance, rock properties, fluid properties.
