Reservoir Modeling: From RESCUE To RESQML

摘要

The RESCUE consortium formed in 1995 in response to the requirement to transfer the structural framework, 3D gridded models, and associated well data from "geomodels to upscalers." RESCUE developed a data standard and libraries that allowed multiple vendors to support subsurface projects across the geoscience and engineering domains. To date, more than 20 of the sponsoring petroleum companies and application vendors have integrated RESCUE into their applications.rnIn late 2008, the consortium began a transition to a much more flexible standard: RESQML™. RESQML joins with WITSML™ and PRODML™ as the latest XML-based data-transfer standards managed by Energistics. The V1.0 developer's release of the RESQML data standard was published in December 2010, followed by a fully commercial Vl.l release in October 2011. We expect vendor applications using RESQML Vl.l to be available commercially in 2012.rnRESQML has been designed to supportrn(a) Interaction with real-time production and drilling domainsrn(b) Transfer of gigacell reservoir-simulation models, as are currently in use in some areas of the world, together with static reservoir models, which may be several orders of magnitude largerrn(c) Lossless data transfer for complex grids, especially for nonstandard connectivityrn(d) Retention of the geologic and geophysical meta-data associated with 3D gridsrn(e) Data standards to support flexible and iterative multivendor subsurface workflows across geology, geophysics, and engineering As an example of the latter, workflows that support fault-seal analysis or 4D-seismic interpretation benefit greatly from the integration of data, metadata, and interpretations from multiple geophysical, geologic, and engineering applications into a coherent subsurface model. Such integration is not possible for a single application or vendor.rnIn this paper, we will present our objectives, challenges, and work plan for 3D/4D-reservoir-model exchange. Details of the technical design defined by participating petroleum oil companies and software vendors will be shared to demonstrate the efficiency of the RESQML standard.
