Anisotropic poroelasticity – Does it apply to shale?
(Journal article; Peer reviewed, 2018)Shale plays an important role as cap rock above oil and gas reservoirs and above e.g. CO2 storage sites, as well as being source and reservoir rock in development of so-called unconventional reserves. Shale anisotropy needs ... -
Application of a Rapid and Simple UV-spectrophotometric method for the study of desorption of esterquat collectors in Tailings-Seawater Systems
(Journal article; Peer reviewed, 2018)The growing demand for mineral resources followed by the steady increase in mining activity result in the need for the disposal of large amount of tailings. Submarine tailings placements (STPs) is a viable option to ... -
Application of Digitalization in Real-Time Analysis of Drilling Dynamics Using Along-String Measurement (ASM) Data Along Wired Pipes
(Peer reviewed; Journal article, 2022)An automated drilling system requires a real-time evaluation of the drilling bit during drilling to optimize operation and determine when to stop drilling and switch bits. Furthermore, in the dynamic modeling of drill ... -
Application of Low-Salinity Waterflooding in Carbonate Cores: A Geochemical Modeling Study
(Peer reviewed; Journal article, 2020)Waterflooding is the most widely applied improved oil recovery technique. Recently, there has been growing interest in the chemistry and ionic composition of the injected water. Low-salinity waterflooding (LSWF) is a ... -
Application of nanoparticles for oil recovery.
(Peer reviewed; Journal article, 2021)Due to their large surface-area-to-volume ratio and enhanced chemical reactivity, nanoparticles have attracted interest among researchers in the upstream petroleum industry for oil recovery applications. Nanoparticles have ... -
Application of nature-inspired algorithms and artificial neural network in waterflooding well control optimization

Application of Soft Data in Nodule Resource Estimation
(Peer reviewed; Journal article, 2020)Minerals and metals are of uttermost importance in our society, and mineral resources on and beneath the deep ocean floor represent a huge potential. Deciding whether mining from the deep ocean floor is financially, ... -
Applying hybrid support vector regression and genetic algorithm to water alternating CO2 gas EOR
(Peer reviewed; Journal article, 2020)Water alternating CO2 gas injection (WAG CO2) is one of the most promising enhanced oil recovery techniques. The optimization of this process requires performing many time‐consuming simulations. In this paper, an intelligent ... -
Approximate reflection coefficients for a thin VTI layer
(Journal article; Peer reviewed, 2018)We have developed an approximate method to derive simple expressions for the reflection coefficients of P- and SV-waves for a thin transversely isotropic layer with a vertical symmetry axis (VTI) embedded in a homogeneous ... -
Architecture of growth basins in a tidally influenced, prodelta to delta-front setting: The Triassic succession of Kvalpynten, East Svalbard
(Journal article; Peer reviewed, 2019)World‐class examples of fault‐controlled growth basins with associated syn‐kinematic sedimentary fill are developed in Upper Triassic prodelta to delta‐front deposits exposed at Kvalpynten, SW Edgeøya in East Svalbard. ... -
