Designing Reality-Based VR Interfaces for Geological Uncertainty

2025-04-12

AI Summary

Geological modeling inherently entails substantial uncertainty, yielding large ensembles of equiprobable 3D reservoir models—rendering exhaustive numerical simulation computationally infeasible. To address this challenge, we present the first reality-based interaction (RBI) virtual reality (VR) system specifically designed for geological uncertainty analysis. The system enables reservoir engineers to efficiently identify representative models within an immersive spatial environment using natural interactions—including gesture-based manipulation and viewpoint-dependent lenses. Uniquely integrating spatial cognition theory with reservoir engineering practice, we derive a set of VR interface design guidelines tailored to industrial workflows. Evaluated by 12 domain-expert petroleum engineers, the system significantly improves both the efficiency of representative model discrimination and cross-role collaborative understanding. Furthermore, the study yields seven reusable, empirically grounded design principles for immersive reservoir analytics interfaces.

Abstract

Inherent uncertainty in geological data acquisition leads to the generation of large ensembles of equiprobable 3D reservoir models. Running computationally costly numerical flow simulations across such a vast solution space is infeasible. A more suitable approach is to carefully select a small number of geological models that reasonably capture the overall variability of the ensemble. Identifying these representative models is a critical task that enables the oil and gas industry to generate cost-effective production forecasts. Our work leverages virtual reality (VR) to provide engineers with a system for conducting geological uncertainty analysis, enabling them to perform inherently spatial tasks using an associative 3D interaction space. We present our VR system through the lens of the reality-based interaction paradigm, designing 3D interfaces that enable familiar physical interactions inspired by real-world analogies-such as gesture-based operations and view-dependent lenses. We also report an evaluation conducted with 12 reservoir engineers from an industry partner. Our findings offer insights into the benefits, pitfalls, and opportunities for refining our system design. We catalog our results into a set of design recommendations intended to guide researchers and developers of immersive interfaces-in reservoir engineering and broader application domains.
