Abstract:
1. An equivalent well block radius determiner machine to determine an equivalent well block radius of a perforated well in a petroleum reservoir simulator, the equivalent well block radius determiner machine comprising: a computer having at least a processor, memory, and a database storing simulated well formation data received from a plurality of petroleum reservoir sensors to thereby define a simulated well formation; a partial penetration factor determiner computer readable program product stored in a tangible computer readable storage medium and including instructions that, when executed by the computer, cause the computer to perform the operation of determining a partial penetration factor for one of one or more well perforations of the simulated well formation responsive to a total quantity count of the one or more well perforations and a ratio of a collective vertical height of the one or more well perforations and a total thickness of the simulated well formation; a vertical flow correction factor computer readable program product stored in a tangible computer readable storage medium and including instructions that, when executed by the computer, cause the computer to perform the operation of determining a vertical flow correction factor for the one of the one or more well perforations responsive to the total quantity count of the one or more well perforations and responsive to determining a location of the one of the one or more well perforations within the simulated well formation; and an equivalent well block radius determiner computer readable program product stored in a tangible computer readable storage medium and including instructions that, when executed by the computer, cause the computer to perform the operation of determining an equivalent well block radius of the one of the one or more well perforations responsive to the partial penetration factor computer readable program product and the vertical flow correction factor computer readable program product.
