Reserve Estimation is an important and essential aspect of petroleum engineering. This is because as we all know the aim of all oil operators is to make profit and accurate reserve estimation so as to help the operator to determine its profit. Without his information, the operator cannot successfully embark on any project. This research works seeks to help find a lasting solution to errors and discrepancy that always arise in the obtained values of reserve in place. This will help the operators to always make decisions under situation of certainty thereby reducing risk. The Oziengbe reservoir, D4 Sand Guico reservoir, wedge shaped reservoir, A2 reservoir and a case study reservoir characteristic were reviewed. Also, all the methods of estimation used to estimate each reservoir were reviewed and objective assessment of each reservoir result was made. Each reservoir showed peculiar property and drive mechanism. Errors and discrepancy in estimation results are best minimized if the data used in obtaining the result are accurate.Keywords

Reserve estimation entails the interpretation of geologic and/ or quantitative calculation of the petro physical data, PVT(Pressure, Volume, and Temperature), and production histories of the reservoir to estimate the reserve1. Reserve estimation using Decline Curve Analysis andMaterial Balance andattempts to answer the question of reserve evaluation based on performance trend. Various techniques have been developed for computing reserve2.This study therefore focused on comparing Decline Curve Analysis and Material Balance using two fields as a case study. These are D4 Sand Guico field, and the Eleke (E1) field. Particular emphasis was laid on the determination of decline rate from the graph of production rate versus cumulative production which was also used to obtain the maximum produced oil and consequently the stock tank oil initially in place (STOIIP) when the decline curve analysis was used.
Since the two reserves used are combination drives, the graph of the variables plotted against each other gave a slope U, known as the reservoir constant and the stock tank oil initially in place as the intercept when the material balance approach was used3.
