“…The GMBE was formulated on a black oil reservoir and consequently, is not directly applicable for volatile oil or gas-condensate reservoirs. Besides, this model is not able to cover naturally fractured reservoirs as uniform porosity was considered (Bashiri et al 2011).…”

Engineers have been using the material balance equation (MBE) for almost the last five decades to estimate cumulative production. However, it still is an effective tool to estimate the original hydrocarbon (oil and gas) available in the reservoir. The conventional material balance method has been successfully applying for the regular structure of a typical reservoir. In this method, all formation properties are assumed constant. However, it is very important to take care of the alteration of rock and fluid properties concerning space and time during the production history of the reservoir. Therefore, there is an immense need to understand how rocks and fluid properties change with space and time. In this paper, a thorough review and critical analysis of MBE are presented so that researchers can find a solution to why and how the incorporation of continuous alteration phenomena is needed to be considered during the development of new and dynamic MBE. Besides, the need for incorporation of all unconventional properties is detailed in this review research This review will help the new researcher to get a guideline for starting further research on the material balance equation. This study makes a crucial scope for carrying research to make a way out for the nonlinear behavior of the reservoir. This article also shows how different unconventional properties of the reservoir have been overlooked in many researches works. Finally, a guideline is provided to overcome the previous challenges in estimating hydrocarbon reserve, and workflow is presented to develop a new dynamic MBE.

In recent years, M oilfield has entered into high water cut stage. Two main problems are imposed in the process of development including sharp water cut rising rate and rapid oil production decline. These problems are difficult to solve, which may bring other problems. In order to slow down production decline rate and control the rising rate of water cut, it is necessary to control water injection rate. However, oil production rate can be affected if water injection rate is too low to provide enough water volume for maintaining reservoir pressure. A method to calculate reasonable injection-production ratio and predict water cut is provided in this paper. Its main mechanism is to resolve above contradictions by calculating reasonable water injection rate. Firstly, an equation to calculate reasonable injection-production ratio is deduced by material balance equation. It considers several parameters including rate of pressure recovery, water cut and other production indexes. Secondly, reasonable oil production rates and water cut of future 10 years are predicted. Oil production is predicted by the law of production decline, and water cut is predicted by regression equation of water drive characteristic curve. Lastly, reasonable water injection rates of next 10 years are calculated through predicted injection-production ratios and liquid production rates. Taking M oilfield as an example, this paper presents a method to determine reasonable water injection rate of multilayer sandstone water drive reservoir.Keywords Reasonable water injection rate Á Reasonable reservoir pressure Á Material balance equation Á Anticline multilayer sandstone water drive reservoir
