Problem and models of multicriteria decision making and risk assessment of the arctic offshore oil and gas field development
(Peer reviewed; Journal article, 2019)The article is devoted to the systematic solution of problems of multi-criteria assessment and the possibility of implementing projects for the development of hydrocarbon deposits on the Arctic shelf under conditions of ... -
Machine learning in reservoir permeability prediction and modelling of fluid flow in porous media
(Peer reviewed; Journal article, 2019)Reliable data on the properties of the porous medium are necessary for the correct description of the process of displacing hydrocarbons from the reservoirs and forecasting reservoir performance. The true permeability of ... -
Application of multicriteria fuzzy clusterization approach to assess the arctic seas oil and gas field development prospects
(Peer reviewed; Journal article, 2019)The article describes a unified approach to the assessment of resources and business planning. As an example, the oil and gas resources of the Pechora Sea are considered in the paper. Based on the specifics of the problem ... -
Numerical Modelling and Sensitivity Analysis of Gas Kick Migration and Unloading of Riser
(Chapter, 2019)In deepwater wells there is a risk of gas entering the riser. This can be caused by gas being trapped by the BOP after a well kill operation, or it can be that the BOP was not closed quickly enough upon kick detection. ... -
Hydraulic Behavior in Cased and Open Hole Sections in Highly Deviated Wellbores
(Chapter, 2019)In this paper we present results from flow loop experiments with an oil-based drilling fluid with micronized barite as weight materials. The use of micronized barite allows using lower viscosity drilling fluid, providing ... -
Experimental Investigation of the Mechanisms of Salt Precipitation during CO2 Injection in Sandstone
(Peer reviewed; Journal article, 2019)Deep saline reservoirs have the highest volumetric CO2 storage potential, but drying and salt precipitation during CO2 injection could severely impair CO2 injectivity. The physical mechanisms and impact of salt precipitation, ... -
Natural gas: A transition fuel for sustainable energy system transformation?
(Peer reviewed; Journal article, 2019)Current discourse on the transition to a decarbonized energy system future is dominated by renewable energy solutions. Initial conditions for this transition may vary across different regions and countries. There are, ... -
Numerical investigation of the impacts of borehole breakouts on breakdown pressure
(Peer reviewed; Journal article, 2019)Borehole breakouts appear in drilling and production operations when rock subjected to in situ stress experiences shear failure. However, if a borehole breakout occurs, the boundary of the borehole is no longer circular ... -
Cfd analysis of low frequency oscillations in Newtonian and non-Newtonian fluids in a vertical pipe
(Peer reviewed; Journal article, 2019)The effect of vertically imposed, low frequency oscillations on the rheology of shear-thinning non- Newtonian fluids are studied numerically by computational fluid dynamics (CFD). Both Newtonian (water) and inelastic ... -
Concentric cylinder viscometer flows of Herschel-Bulkley fluids
(Peer reviewed; Journal article, 2019)Drilling fluids and well cements are example non-Newtonian fluids that are used for geothermal and petroleum well construction. Measurement of the non-Newtonian fluid viscosities are normally performed using a concentric ... -
Effect of Salts on Interfacial Tension and CO2 Mass Transfer in Carbonated Water Injection
(Journal article; Peer reviewed, 2019-02)Carbonated water injection (CWI) is a promising enhanced oil recovery (EOR) and CO2 sequestration method, which overcomes the problems associated with CO2 EOR. CO2 mass transfer and interfacial tension (IFT) are important ... -
Effect of salinity on silica nanoparticle adsorption kinetics and mechanisms for fluid/rock interaction with calcite
(Peer reviewed; Journal article, 2019-02)This study addresses the kinetics of silica nanoparticle adsorption on calcite from a solution at three salinities: deionized water (DIW), synthetic seawater (SSW), and low salinity water (LSW). The nanoparticle adsorption ... -
Influence of Individual Ions on Silica Nanoparticles Interaction with Berea Sandstone Minerals
(Journal article; Peer reviewed, 2019-09)Nanofluids are prepared by dispersing silica nanoparticles in aqueous media (brines). The purpose of this work is to address brine/rock interactions in presence of nanoparticles. Our previous studies have shown that silica ... -
Mineral replacement in long-term flooded porous carbonate rocks
(Peer reviewed; Journal article, 2019-09)This study reports mineralogical and physical property changes linked to geo-chemical alterations processes during three ultra-long-term tri-axial tests on outcrop-chalk from Liège (Belgium). The test core plugs were flooded ... -
Plug & abandonment of offshore wells: Ensuring long-term well integrity and cost-efficiency
(Peer reviewed; Journal article, 2019-10)There is an upcoming "P&A wave" of wells that need to be permanently plugged and abandoned, especially in mature, offshore areas such as the North Sea and Gulf of Mexico. It is important to ensure that plugged wells do not ... -
A Hierarchy of Non-Equilibrium Two-Phase Flow Models
(Journal article; Peer reviewed, 2019-10)We review and extend a hierarchy of relaxation models for two-phase flow. The models are derived from the non-equilibrium Baer–Nunziato model, which is endowed with relaxation source terms to drive it towards equilibrium. ... -
Review of Experimental Sorption Studies of CO2 and CH4 in Shales
(Journal article; Peer reviewed, 2019-10)In recent years CO2 injection in shale has been investigated with aim to enhance shale gas recovery (ESGR) and permanently sequester CO2. This paper reviews the state of research on CH4 and CO2 sorption in shale. We present ... -
