Usage of sparse matrix methods in material balance calculations
The Chemical Engineering Journal, 1981Abstract The material balance equations for a variety of related chemical commodities manufactured in one large co-sited complex or several such complexes are linear in nature and can be written in matrix form. Also, because generally only one to three raw materials are required in the manufacture of each commodity which, in turn, may be used in the ...

Analysis of Gas Production Data Using Flowing Material Balance Method
SPE Nigeria Annual International Conference and Exhibition, 2013Abstract This paper presents an analytical derivation that constitutes a sound theoretical background for gas flow equation. This gas flow equation is based on a new pseudotime function which, unlike the computation of material balance pseudotime, is insensitive to time step-size and purely analytical. This new pseudotime function offers

Improvements to Reservoir Material Balance Methods
SPE Annual Technical Conference and Exhibition, 2000Abstract Experience with a number of material balance data sets from the field and from simulation has revealed some procedures that can be used to improve analysis of both oil and gas reservoirs: Failure to account for a weak water drive can result in material balance errors that are not insignificant.The assertion of previous authors ...

Formation Pressure Calculation Based on Modified Flowing Material Balance Method
Advanced Materials Research, 2014Formation pressure is an important symbol of driving energy and the key problem of gas reservoir development. Therefore, the formation pressure’s evaluation is a very important work. Due to the invasion of edge-bottom water, using conventional "flow" material balance method to calculate the formation pressure is no longer applicable.

Method for calculating material balance of complex process flowcharts
Journal of Mathematical Chemistry, 2020When developing, analyzing, and optimizing chemical production technologies, one should first calculate the material and heat balances in order to quantify the products and wastes produced, the reagents and energy consumed, as well as to determine characteristics of equipment required.

Material Balance of Fractured Fields–Double Reservoir Method
Latin American & Caribbean Petroleum Engineering Conference, 2007Abstract The conventional material balance methodology for fractured fields considers a single system with double porosity, compressibility, saturations, etc. The method proposed in this paper employs a double reservoir concept.

A Statistical Approach to Material Balance Methods
SPE Annual Technical Conference and Exhibition, 1994Abstract Material balance methods have been used in petroleum engineering for many years to evaluate the performance of oil and gas reservoirs. It has been previously shown that in many cases the standard material balance equation results in a linear form that is particularly convenient for graphical analysis.

Improvements to the Dynamic Material-Balance Method of Reservoir Surveillance
SPE Nigeria Annual International Conference and Exhibition, 2019Abstract Given sufficient performance and other data, material balance (MB) is a common method of determining the hydrocarbons initially in-place (HCIIP) in a reservoir. The application of this method requires, as a minimum, historic cumulative production (including injection) and average reservoir pressure.

How Powerful Material Balance Analysis Method for Predicting Gas Flooding Performance
SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, 2015Abstract Gas Flooding is one of the reservoir production management methods which commonly used in the petroleum industry in order to improve oil recoveries and maintaining reservoir pressure. This study discusses two methods in analyzing gas flooding, i.e., material balance analysis and reservoir simulation methods.
