Abstract: Embodiments for parallel production simulation of an oil field are disclosed. A plurality of production parameter data sets corresponding respectively to a plurality of scenarios are received and aligned in a memory of a vectorized computation hardware. In SIMT-based architecture, each well of each scenario is associated with a thread of a plurality of threads. In a SIMD-based architecture, each well of each scenario is associated with a respective lane of a multi-lane data pipeline.

Abstract: A method of improving the production of a mature gas or oil field, the field comprising a plurality of existing wells, the method comprising the steps of providing a field simulator capable of predicting a production of the field in function of a given scenario, a scenario being a set of data comprising production parameters of the existing wells and, the case may be, location and production parameters of one or more new wells, determining drainage areas of the existing wells using the field simulator, determining locations of candidate new wells such that drainage areas of the candidate new wells, determined using the field simulator, do not overlap with the drainage areas of the existing wells, optimizing the value of a gain function which depends on the field production by determining a set of wells out of a plurality of sets of wells, which optimize the value of said gain function, each set of wells of said plurality of sets of wells comprising the existing wells and new wells selected among the candidate

Abstract: An x-ray CT system performs a scan by acquiring projection views from which an image is reconstructed. In a prospective embodiment, the correlation of adjacent views is calculated as the scan is performed and is used to detect subject motion as the scan is being performed. In a retrospective embodiment, the correlation of adjacent views is calculated and is used to detect subject motion after the scan is completed. In the first embodiment substitute projection views are acquired by continuing the scan and in the second embodiment redundant projection views acquired during the scan are substituted until the best possible image is produced.
