“…Therefore, if F (p) < 0, it is an anticline, otherwise it is a syncline. In this work we chose the Hermite-Birkhoff Radial Basis Function (HBRBF) interpolation [Pereira et al 2011] as our function F . HBRBFs create implicit surfaces that can interpolate: values, gradients, or values and gradients at a point in space, which is a good fit for our problem of interpolating contacts and dip directions.…”

Figure 1: Interpreting a sketched geologic map to generate a 3D geologic model. From left to right, sketched geologic map, generated 3D model, and exploded view of the model. AbstractConstructing 3D geological models is a fundamental task in oil/gas exploration and production. A critical stage in the existing 3D geological modeling workflow is moving from a geological interpretation (usually 2D) to a 3D geological model. The construction of 3D geological models can be a cumbersome task mainly because of the models' complexity, and inconsistencies between the interpretation and modeling tasks. To narrow the gap between interpretation and modeling tasks, we propose a sketched based approach. Our main goal is to mimic how domain experts interpret geological structures and allow the creation of models directly from the interpretation task, therefore avoiding the drawbacks of a separate modeling stage. Our sketch-based modeler is based on standard annotations of 2D geological maps and on geologists' interpretation sketches. Specific geological rules and constraints are applied and evaluated during the sketch-based modeling process to guarantee the construction of a valid 3D geologic model.

“…Sketch-based interface and modelling (SBIM) is an approach for rapid model creation that is used for prototyping in many nongeological CAD and CFD applications (e.g. Olsen et al 2009Olsen et al , 2011Pereira et al 2011). SBIM allows model concepts to be rapidly sketched and tested.…”

Geological modelling is widely used to predict resource potential in subsurface reservoirs. However, modelling is often slow, requires use of mathematical methods that are unfamiliar to many geoscientists and is implemented in expert software. We demonstrate here an alternative approach using Sketch-Based Interface and Modelling (SBIM) that allows rapid creation of complex three-dimensional (3D) models from 2D sketches. Sketches, either on vertical cross-sections or in map-view, are converted to 3D surfaces that outline geological interpretations. A suite of geological operators is proposed that handle interactions between the surfaces to form a geologically realistic 3D model. These operators deliver the flexibility to sketch a geological model in any order and provide an intuitive framework for geoscientists to rapidly create 3D models. Two case studies are presented, demonstrating scenarios in which different approaches to model sketching are used depending on the geological setting and available data. These case studies show the strengths of sketching with geological operators. Sketched 3D models can be queried visually or quantitatively to provide insights into heterogeneity distribution, facies connectivity or dynamic model behaviour; this information cannot be obtained by sketching in 2D or on paper.Supplementary material:https://doi.org/10.6084/m9.figshare.c.5303043
