| Summary: | Analysis of commingled reservoirs from limited data can be a and the BHFP- Each layer within the commingled model is challenge to most conventional reservoir engineering tools. commingled system. concluded that the Layered PSS Model also under-estimates the data for the hypothetical commingled reservoirs. The model defined by two parameters (OGIP and the gas flow coefficient, effectively used to model any number of layers in a equation with the PSS flow equation for gas and can be for any rate-time data was suggested. forecast if any transient data were included. It was also gas reservoirs was developed and used to analyze the ratetime hypothetical layers. These data were added together in intervals rather than the whole data is useful in identifying Jg). This model couples the material balance (M. B.) layer. The Layered PSS Model gave satisfactory results and layers used in the analysis. The effect of Non-Darcy flow layers. It was shown that the analysis of selective not have a significant effect on the model answers for tight performance. A Layered PseudoSteady-State (PSS) Model for rate with the model. An optimization routine was coupled to requires only an estimate for the initial reservoir pressure reservoir simulator was used to generate rate-time data for reservoirs. A two-dimensional, finite difference, gas several combinations to simulate commingled reservoirs' rate technique that can be used to estimate the OGIP and predict that are in the PSS period. The effect of transient data on The analysis is done through history-matching the production the best parameters that describe the performance of each the commingled reservoirs are larger than the number of the match with the simulation data was excellent for cases the model always gives conservative OGIP and conservative the model answers was also investigated. It was found that the model to aid in the matching process and help determining The purpose of this research is to find an effective and easy the reservoir performance for tight commingled gas total OGIP for a commingled system if the number of layers in transients and commingling. Also, an analysis methodology was also studied. It was found that the non-darcy flow does |
