Reaction kinetics determined from core flooding and steady state principles for Stevns Klint and Kansas chalk injected with MgCl2 brine at reservoir temperature
(Peer reviewed; Journal article, 2022)A methodology is presented for determining reaction kinetics from core flooding: A core is flooded with reactive brine at different compositions with injection rates varied systematically. Each combination is performed ... -
Resistivity of reservoir sandstones and organic rich shales on the Barents Shelf: Implications for interpreting CSEM data
(Peer reviewed; Journal article, 2021-11)Marine controlled source electromagnetic (CSEM) data have been utilized in the past decade during petroleum exploration of the Barents Shelf, particularly for de-risking the highly porous sandstone reservoirs of the Upper ... -
Review of Different Methods for Identification of Transients in Pressure Measurements by Permanent Downhole Gauges Installed in Wells
(Peer reviewed; Journal article, 2023)Permanent downhole gauges (PDG) are massively installed in injection and production wells operated in different industries such as oil and gas, geological CO2 storage, and the geothermal industry. These gauges provide a ... -
Rigorous Connectionist Models to Predict Carbon Dioxide Solubility in Various Ionic Liquids
(Journal article; Peer reviewed, 2020-01)Estimating the solubility of carbon dioxide in ionic liquids, using reliable models, is of paramount importance from both environmental and economic points of view. In this regard, the current research aims at evaluating ... -
Rotary steerable systems: mathematical modeling and their case study
(Peer reviewed; Journal article, 2021-05)Directional drilling is a common and essential procedure of major extended reach drilling operations. With the development of directional drilling technologies, the percentage of recoverable oil production has increased. ... -
A Second-Order Finite Volume Method for Field-Scale Reservoir Simulation
(Peer reviewed; Journal article, 2023-08)Subsurface reservoirs are large complex systems. Reservoir flow models are defined on complex grids that follow geology with relatively large block sizes to make consistent simulations feasible. Reservoir engineers rely ... -
A sequential decision and data analytics framework for maximizing value and reliability of CO2 storage monitoring
(Peer reviewed; Journal article, 2021-12)Carbon capture and sequestration (carbon capture and storage or CCS) represents a unique potential strategy that can minimize CO2 emissions in the atmosphere, and it creates a pathway toward a neutral carbon balance, which ... -
Simulation of immiscible WAG injection in a stratified reservoir -- performance characterization using a new dimensionless number
(Peer reviewed; Journal article, 2019)Water alternating gas (WAG) is a well‐established enhanced‐oil‐recovery process where gas and water are injected in alternating fashion. Good volumetric sweep is achieved as water and gas target both the oil residing in ... -
Simulation study of wettability alteration enhanced oil recovery during co-current spontaneous imbibition
(Peer reviewed; Journal article, 2020-09)Naturally fractured reservoirs are highly dependent on capillary forces to recover hydrocarbons during water injection. Water can spontaneously imbibe and expel oil if positive capillary forces exist; purely counter-current ... -
Simulation study of wettability alteration enhanced oil recovery during co-current spontaneous imbibition
(Peer reviewed; Journal article, 2020)Naturally fractured reservoirs are highly dependent on capillary forces to recover hydrocarbons during water injection. Water can spontaneously imbibe and expel oil if positive capillary forces exist; purely counter-current ... -
Steady State Gas Flow from Tight Shale Matrix Subject to Water Blocking
(Peer reviewed; Journal article, 2021)This work studies 1D steady-state flow of gas from compressible shale matrix subject to water blocking toward a neighboring fracture. Water blocking is a capillary end effect causing wetting phase (e.g., water) to accumulate ... -
Steady State Relative Permeability Experiments with Capillary End Effects: Analytical Solutions including Derivation of the Intercept Method
(Peer reviewed; Journal article, 2020-04)Steady state relative permeability experiments are performed by coinjection of two (or more) immiscible fluids. The relative permeabilities can be calculated directly from the stabilized pressure drop and saturation of the ... -

Structural evolution of sheared margin basins: the role of strain partitioning. Sørvestsnaget Basin, Norwegian Barents Sea
(Journal article; Peer reviewed, 2017-07)Spatio-temporal analysis of basins formed along sheared margins has received much less attention than those formed along orthogonally extended margins. Knowledge about the structural evolution of such basins is important ... -
Structural geologic modeling and restoration using ensemble Kalman inversion
(Peer reviewed; Journal article, 2023-06)We demonstrate the use of Ensemble Kalman Inversion (EKI) for building three-dimensional, multi-fault, kinematically restorable structural geologic models, by means of a workflow in which fault geometry, the distribution ... -
Theoretical Comparison of Two Setups for Capillary Pressure Measurement by Centrifuge
(Peer reviewed; Journal article, 2022)There are several approaches for the calculation of capillary pressure curves in porous media including the centrifuge method. In this work, a new installation of centrifuge test is introduced and compared with the traditional ... -
