Combined positron emission tomography and computed tomography to visualize and quantify fluid flow in sedimentary rocks
Fernø, Martin; Gauteplass, Jarand; Hauge, Lars Petter; Abell, Geir Espen; Adamsen, Tom Christian; Graue, Arne (Peer reviewed; Journal article, 2015-09-22)Here we show for the first time the combined positron emission tomography (PET) and computed tomography (CT) imaging of flow processes within porous rocks to quantify the development in local fluid saturations. The coupling ... -
Core-scale sensitivity study of CO2 foam injection strategies for mobility control, enhanced oil recovery, and CO2 storage
Alcorn, Zachary Paul; Fredriksen, Sunniva; Sharma, Mohan; Føyen, Tore Lyngås; Wergeland, Connie; Fernø, Martin; Graue, Arne; Ersland, Geir (Journal article; Peer reviewed, 2020)This paper presents experimental and numerical sensitivity studies to assist injection strategy design for an ongoing CO2 foam field pilot. The aim is to increase the success of in-situ CO2 foam generation and propagation ... -
Effects of salinity on hydrate stability and implications for storage of CO2 in natural gas hydrate reservoirs
Husebø, Jarle; Ersland, Geir; Graue, Arne; Kvamme, Bjørn (Peer reviewed; Journal article, 2009-02)The win-win situation of CO2 storage in natural gas hydrate reservoirs is attractive for several reasons in addition to the associated natural gas production. Since both pure CO2 and pure methane form structure I hydrate ... -
Enabling Large-Scale Carbon Capture, Utilisation, and Storage (CCUS) Using Offshore Carbon Dioxide (CO2) Infrastructure Developments - A Review
Eide, Lars Ingolf; Batum, Melissa; Dixon, Tim; Elamin, Zabia; Graue, Arne; Hagen, Sveinung; Hovorka, Susan; Nazarian, Bamshad; Nøkleby, Pål Helge; Olsen, Geir Inge; Ringrose, Philip; Vieira, Raphael Augusto Mello (Journal article; Peer reviewed, 2019)Presently, the only offshore project for enhanced oil recovery using carbon dioxide, known as CO2-EOR, is in Brazil. Several desk studies have been undertaken, without any projects being implemented. The objective of this ... -
Flow visualization of CO2 in tight shale formations at reservoir conditions
Fernø, Martin; Hauge, Lars Petter; Rognmo, Arthur Uno; Gauteplass, Jarand; Graue, Arne (Peer reviewed; Journal article, 2015-09-18)The flow of CO2 in porous media is fundamental to many engineering applications and geophysical processes. Yet detailed CO2 flow visualization remains challenging. We address this problem via positron emission tomography ... -
Transport and storage of CO2 in natural gas hydrate reservoirs
Ersland, Geir; Husebø, Jarle; Graue, Arne; Kvamme, Bjørn (Peer reviewed; Journal article, 2009-02)Storage of CO2 in natural gas hydrate reservoirs may offer stable long term deposition of a greenhouse gas while benefiting from methane production, without requiring heat. By exposing hydrate to a thermodynamically preferred ... -
Transport mechanisms for CO2-CH4 exchange and safe CO2 storage in hydrate-bearing sandstone
Birkedal, Knut Arne; Hauge, Lars Petter; Graue, Arne; Ersland, Geir (Peer reviewed; Journal article, 2015-06-08)CO2 injection in hydrate-bearing sediments induces methane (CH4) production while benefitting from CO2 storage, as demonstrated in both core and field scale studies. CH4 hydrates have been formed repeatedly in partially ...
