Application of machine learning to assess the value of information in polymer flooding
(Peer reviewed; Journal article, 2021-12)In this work, we provide a more consistent alternative for performing value of information (VOI) analyses to address sequential decision problems in reservoir management and generate insights on the process of reservoir ... -
Appraisal campaign selection based on the maximum value of sequential information
(Peer reviewed; Journal article, 2021-09)Field development projects generally demand large investments which are subject to geological uncertainty, hence projects can benefit from geological information obtained from appraisal wells before large capital commitment. ... -
Determination of phase-partitioning tracer candidates in production waters from oilfields based on solid-phase microextraction followed by gas chromatography-tandem mass spectrometry
(Peer reviewed; Journal article, 2020-08)In the present document, we report the development of an analytical method consisting of a sequential direct-immersion/headspace solid-phase microextraction (DI-HS-SPME) followed by gas-phase chromatography and tandem mass ... -
Efficient Dimensionality Reduction Methods in Reservoir History Matching
(Peer reviewed; Journal article, 2021-05)Production forecasting is the basis for decision making in the oil and gas industry, and can be quite challenging, especially in terms of complex geological modeling of the subsurface. To help solve this problem, assisted ... -
Mineralogy and geochemistry of reservoir and non-reservoir chalk from the Norwegian continental shelf
(Peer reviewed; Journal article, 2021-05)A first and detailed study of the geochemistry and mineralogy characterizing the North Sea reservoir and non-reservoir chalk is provided in this work. The study is based on 185 cores from exploration and development wells ... -
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. ... -
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 ... -
A Visual Investigation of CO2 Convective Mixing in Water and Oil at the Pore Scale Using a Micromodel Apparatus at Reservoir Conditions
(Peer reviewed; Journal article, 2021-01)CO2 convective mixing in water has been visualized in Hele-Shaw and PVT cell experiments but not at the pore scale. Furthermore, CO2 convective mixing in a three-phase system (i.e., CO2 in the presence of both water and ...
