The non-uniqueness problem, however, brings about confusion in selecting the correct reservoir model using the conventional approaches.
The non-uniqueness problem always brings about confusion in selecting the correct reservoir model using the conventional interpretation approaches.
Athichanagorn and Horne (1995) presented an ANN approach combined with the sequential predictive probability (SPP) method to diagnose the correct reservoir models from the derivative plots.
Assumption of correct reservoir fluid (oil) composition is the basis of the most quality control methods presented in the literature, which are used for checking the accuracy of related experiments for thermodynamic phase behavior of reservoir oil (PVT experiments).
The correct reservoir wetting equilibrium is obtained when the AN of the crude oil in the pores is the same as the AN in the original reservoir crude oil.
The validation results using the real field buildup test data confirm that the proposed models generate reliable results both in the case of identifying the correct reservoir models and estimating the model-related parameters using the pressure derivative plots compared to the results of conventional well-testing analysis techniques. 8.
There was the attempt to use small nuclear bombs for peaceful purposes, to aid in oil and gas drilling, to put out fires in oil and gas wells, to create underground storage space for hazardous wastes and to dig canals, harbors and reservoirs ("correcting the mistakes of nature," the Soviets said).
In this case, the composition of the injected water (column inlet) was specified using the actual measured pH and species concentrations in the influent reservoir, but correcting the total dissolved carbonate concentration to yield ion charge balance (Table 1).
All resistivity measurements were corrected for a reservoir temperature of 80 °C during data processing.
Based on the high-density well pattern and single sand body configuration research in the Xingbei Research Area, this research applies the single sand body modelling technology to model the single sand body structure and the physical property distribution of the space in the research area (Fig. 4 shows the technical route), which lays the foundation for a correct numerical reservoir simulation.
