SummaryThe 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.In 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 V1.1 release in October 2011. We expect vendor applications using RESQML V1.1 to be available commercially in 2012.RESQML has been designed to supportInteraction with real-time production and drilling domains 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 larger Lossless data transfer for complex grids, especially for nonstandard connectivity Retention of the geologic and geophysical meta-data associated with 3D grids 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.In 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.
