Aging and Temperature Effects on the Performance of Sustainable One-Part Geopolymers Developed for Well-Cementing Applications
(Peer reviewed; Journal article, 2023)This study elucidates the effects of aging and temperature over the performance of one-part “just add water” (JAW) granite-based geopolymers for application in well cementing and well abandonment. Additionally, the ... -
cdem: A macOS program for discrete element modeling of tectonic structures
(Peer reviewed; Journal article, 2023-08)cdem is a macOS document-based application for two-dimensional discrete element modeling of tectonic structures and their associated deformation. Documents encapsulate simulations that can be run and explored simultaneously. ... -
Design and Early Age Performance of Sustainable One-Part Geopolymers for Well Cementing
(Peer reviewed; Journal article, 2023-10)One-part geopolymers, known as “just add water” (JAW), alkali-activated formulation is presented in this work. This work reveals the design and development of short-term properties of JAW geopolymers for use in oilwell ... -
Discovery of shale gas in organic rich Jurassic successions, Adventdalen, Central Spitsbergen, Norway
(Journal article; Peer reviewed, 2020-01)Thermogenic dry gas flowed from Jurassic sections in the DH5R research well drilled onshore in Adventdalen, central Spitsbergen, Arctic Norway. The DH5R gas originates from the organic-rich units of the mudstone-dominated ... -
Numerical investigation on blast-induced rock fragmentation with different stemming structures
(Peer reviewed; Journal article, 2023-09)Stemming is one of the main concerns in blast of rock engineering due to its impact on explosion energy consumption and rock excavation performance. In this study, blast-induced rock fragmentation under different stemming ... -
Rheological Compatibility of a Hardening Spacer Fluid and Oil-based Drilling Fluid
(Peer reviewed; Journal article, 2023-08)In the placement process of the cement slurry, treatment fluids such as the spacer are pumped ahead of the cementitious slurry to minimize the contamination of the slurry by drilling fluid and ensure superior bonding to ... -
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 ... -
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 ... -
Zonal Isolation Material for Low-Temperature Shallow-Depth Application: Evaluation of Early Properties Development
(Peer reviewed; Journal article, 2023)Shallow-depth cementing presents unique challenges due to its low temperature and low pore pressure characteristic. The curing process of the cementitious material is typically prolonged at low temperatures resulting in a ...
