... (0.5 cm 3 gradations). Production samples were acquired at fixed intevals within each flood, and oil and water within each sample was visually measured to obtain the material balance cumulative oil production as a function of pore volumes (PV) water or chemical injected. In addition to material...

... On the other hand Advanced Production Data Analysis (APDA), also known as Production Data Analysis (PDA), deals with material balance and PTA at once. These methods are founded in the same analytical principals of PTA; however it focuses in the analysis of the pseudosteady-state reservoir flow...

... Abstract Various forms of shale gas ( SG ) material balance equations ( MBE ) have been developed in the past several decades, dating back to the first round of coalbed methane ( CBM )/ SG development in North America. These equations attempt to incorporate various aspects of SG storage...

This concept permits creation of synthetic production logs over time, to calculate production decline. We introduce the integrated utilization of material balance, flow-pressure algorithms, fluid data...

Finally the paper closes with a review of material balance reserve concerns and best practices. The SPE guidelines give more discretion to the evaluator...

... Abstract Material balance evaluation (MBE) has long been identified as a useful means of establishing connected hydrocarbon volume initially in place and reservoir drive mechanism 1 , 2 . Analysis of MBE results can also prove invaluable in addressing questions on reservoir...
