Early field planning using optimisation and considering uncertainties - Study case: Offshore deepwater field in Brazil
(Peer reviewed; Journal article, 2021)During early phases of oil field development, field planners must decide upon the optimal number of wells and optimal field plateau rate, usually by performing sensitivity studies. These design choices are then “frozen” ... -
Early History Matching of the Ivar Aasen Field
(Master thesis, 2017)Dynamic reservoir simulation models are used to better understand the reservoir and predict future reservoir performance. Once a field starts to produce, a continuous flow of dynamic data becomes available in terms of ... -
Early Holocene thinning and final demise of the Scandinavian Ice Sheet across the main drainage divide of southern Norway
(Journal article; Peer reviewed, 2023)The thinning and final decay of the Scandinavian Ice Sheet in the Gudbrandsdalen area in central southern Norway is described, based on (1) cosmogenic 10Be surface exposure dating of 25 glacially transported boulders, (2) ... -
Early Stage Decisions in Marine Systems Design for Deep-Sea Mining
(Peer reviewed; Journal article, 2022)This article studies the prospects for deep seabed mining as a future viable maritime industry, and discuss the commercial, operational, and technical viability of deep seabed mining. By the use of a business development ... -
Earthquake and Monsoon Induced Slope Failure Effects on Hydropower Projects - An Analysis Along the Sunkoshi Valley, Nepal
(Master thesis, 2016)Due to various reasons like fragile geology, steep topography, highly varying climate and rainfall, many slope failures of varying sizes are very common in Nepal. Every year a lot of those events occur which cause a huge ... -
Eavesdropping at the Speed of Light: Distributed Acoustic Sensing of Baleen Whales in the Arctic
(Peer reviewed; Journal article, 2022)In a post-industrial whaling world, flagship and charismatic baleen whale species are indicators of the health of our oceans. However, traditional monitoring methods provide spatially and temporally undersampled data to ... -
ECD - Effect of Cuttings
(Master thesis, 2010)It is well known when it comes to well planning that ECD management is an important topics. This is to avoid problems like kick, losses, fluid influx into the well and fracturing the formation among others. As more complex ... -
Economic block model development for mining seafloor massive sulfides
(Journal article; Peer reviewed, 2018)To support open-pit studies related to seafloor massive sulfides mining projects, an economic block-model is required. A modular framework is proposed to produce economic block models accommodating various levels of data. ... -
Economic Optimization of Shale Wells
(Master thesis, 2015)The worldwide interest in development of unconventional resources resulted into significant changes in the energy market within the last decade. Successful shale revolution in the US opened global perspectives for extensive ... -
Effect of anelastic patchy saturated sand layers on the reflection and transmission responses of a periodically layered medium
(Journal article; Peer reviewed, 2016)Based on analytic relations, we compute the reflection and transmission responses of a periodically layered medium with a stack of elastic shales and partially saturated sands. The sand layers are considered anelastic ... -
Effect of Barite on the Rheological Properties of an Oil-Based Drilling Fluid
(Peer reviewed; Journal article, 2020) -
Effect of CO2 tax on energy use in oil production: waterflooding optimization under different emission costs
(Peer reviewed; Journal article, 2022)Tackling emissions from hydrocarbon production is a necessity because hydrocarbon production will last for a prolonged time. As a popular hydrocarbon production method, waterflooding operation is energy-intensive and ... -
Effect of convective mixing process on storage of CO2 in saline aquifers with layered permeability.
(Journal article, 2021)Convective mixing of free-phase CO2 and brine in saline aquifers is an established technique to accelerate the CO2 dissolution process. Correct estimation of the convection onset time and rate of CO2 dissolution into brine ... -
Effect of Curvature on Seismic Data and Amplitude Analysis: A Modeling Study
(Master thesis, 2014)The effect of curvature upon AVO-analysis and the capability of Kirchhoff time migration to remove these effects were investigated in this thesis. Curvature focuses or de-focuses seismic waves depending on the shape of the ... -
Effect of drill pipe orbital motion on non-Newtonian fluid flow in an eccentric wellbore: a study with computational fluid dynamics
(Peer reviewed; Journal article, 2021)To ensure an effective drilling operation of an explored well, the associated hydraulics program should be established carefully based on the correct prediction of a drilling fluid’s pressure drop and velocity field. For ... -
Effect of drill string lateral vibrations on wellbore stability and optimal mud pressure determination
(Journal article; Peer reviewed, 2025)Wellbore instability is a critical issue in drilling operations, contributing to significant non-productive time and costly delays. While previous studies have focused on physicochemical and mechanical causes of wellbore ... -
