Reservoir simulations and monitoring of CO 2 storage require specific petrophysical data. We show and illustrate an integrated workflow dedicated to CO 2, including log data analysis and laboratory measurements. This workflow has been applied on the Ketzin site. Carbon dioxide has been injected into a saline aquifer of the Triassic Stuttgart Formation in an anticlinal structure of the northeast German Basin. Two observation wells are used to detect the CO 2 plume arrival time. Resistivity sensors monitor the change of the resistivity map during injection. For reservoir simulations, capillary pressure and relative permeability in drainage and imbibition are necessary. For monitoring purposes, formation factor, drainage and imbibition resistivity index curves are necessary. These data have been acquired using the Fast Resistivity Index Measurement method in drainage and imbibition. Finally, the caprock has also been considered.

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 which allowed multiple vendors to support subsurface projects across the geoscience and engineering domains. To date, over 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. Simple prototype models have already been transferred using RESQML; we expect commercial application in the next 12-24 months. RESQML has been designed to support: a/ Interaction with the real-time production and drilling domains; b/ Transfer of giga-cell reservoir simulation models, as are currently in use in some areas of the world, with static reservoir models which may be several orders of magnitude larger; c/ Loss-less data transfer for complex grids, especially for non-standard connectivity; d/ Retention of the geologic and geophysical meta-data associated with 3D grids; e/ Data standards for flexible and iterative multi-vendor 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, meta-data 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 oil companies and software vendors will be shared to demonstrate the efficiency of the RESQML standard.
