Integrated Approach to Reservoir Simulations for Evaluating Pilot CO<inf>2</inf> Injection in a Depleted Naturally Fractured Oil Field On-Shore Europe
(Journal article; Peer reviewed, 2024)Carbon dioxide capture and storage (CCS) is a necessary requirement for high-emitting CO2 industries to significantly reduce volumes of greenhouse gases released into the atmosphere and mitigate climate change. Geological ... -
Integrated Stress Field Estimation and Implications for Enhanced Geothermal System Development in Acoculco, Mexico
(Journal article; Peer reviewed, 2021)Data gathered from two geothermal exploration wells in the Acoculco caldera, within the Trans-Mexican Volcanic Belt, indicated that temperature is high enough for economic utilization, but permeability is insufficient. ... -
An interactive sequential-decision benchmark from geosteering
(Peer reviewed; Journal article, 2021)During drilling, to maximize future expected production of hydrocarbon resources, the experts commonly adjust the trajectory (geosteer) in response to new insights obtained through real-time measurements. Geosteering ... -
Intrusive generalized polynomial chaos with asynchronous time integration for the solution of the unsteady Navier–Stokes equations
(Journal article; Peer reviewed, 2021)Generalized polynomial chaos provides a reliable framework for many problems of uncertainty quantification in computational fluid dynamics. However, it fails for long-time integration of unsteady problems with stochastic ... -
Investigating the implementation of the safety-diagnosability principle to support defence-in-depth in the nuclear industry: A Fukushima Daiichi accident case study
(Peer reviewed; Journal article, 2021)‘Defence in depth’ (DID) is a fundamental safety principle applied in several industries, including nuclear. The key is to protect safety critical systems by employing multiple layers of protection, i.e. barriers. The ... -
IORSim: A Mathematical Workflow for Field‑Scale Geochemistry Simulations in Porous Media
(Peer reviewed; Journal article, 2024)Reservoir modeling consists of two key components: the reproduction of the historical performance and the prediction of the future reservoir performance. Industry-standard reservoir simulators must run fast on enormous and ... -
Iterative multilevel assimilation of inverted seismic data
(Peer reviewed; Journal article, 2022)In ensemble-based data assimilation (DA), the ensemble size is usually limited to around one hundred. Straightforward application of ensemble-based DA can therefore result in significant Monte Carlo errors, often manifesting ... -
Joint History Matching of Multiple Types of Field Data in a 3D Field-Scale Case Study
(Peer reviewed; Journal article, 2022)This work presents an ensemble-based workflow to simultaneously assimilate multiple types of field data in a proper and consistent manner. The aim of using multiple field datasets is to improve the reliability of estimated ... -
Koherensprodukt fra Sentinel-1
(Research report, 2022)Koherens er en parameter beregna fra målinger av syntetisk aperturradar (SAR), som kan ha stor nytteverdi i analyse av SAR-bilder. Den brukes her til klassifisering og kartlegging av landområder, måldeteksjon og endringsdeteksjon ... -
