Accelerating Ensemble Based Field Characterization Enabled by Grid-Less Multi-Resolution Model

The Project objective is to address an inherent challenge of grid-based model where at the first place the modeler needs to lock the resolution with the grid scale. Due to locking the grid resolution, the log and seismic data needs to be upscaled in that resolution, the original resolution and information gets lost in the model. Grid-less Scalable Earth Modeling is an innovative agile modeling approach that uses all the available data to produce property models that are consistent across all resolutions and all scales. It is a point-based modeling technology; the need to build grids and populate them with properties is deferred until flow simulation or other grid-based processes are run. This grid-less approach has been attempted to build a multi-resolution model which can host multi-resolution model in a shared earth container. In order to demonstrate the power of the grid-less modeling, an extended area has been taken into consideration beyond the field area as the project area of interest. This AOI includes the main field of target with a significant no. of wells (approximately 60 wells) along with a potential near field exploration area towards the south and extended towards North for any future exploration process. The objective of selecting such a mix of areas with variable data cluster is to showcase the value in terms of the below key points: This modeling approach includes a region based VPC modeling to replicate the geological concept in a 3D space away from the well cluster to minimize the biasness of the clustered wellsScalability of grid-less modeling to exhibit the value of downscaling and zooming in the model as and when required to incorporate any geological details and for multi-purpose approach like Field Development, Near Field Exploration and new exploration venture
