Introducing Approximate Well Dynamics into Production Optimization for Operations Scheduling
(Journal article; Peer reviewed, 2020)Most of the literature on short-term production optimization concerns the computation of optimal system settings for steady-state operations. Such methodologies are applicable when the scales of time are faster than reservoir ... -
Introduction to digital core analysis: 3D reconstruction, numerical flow simulations and pore network modeling
(Master thesis, 2017)Digital core analysis can replace the use of conventional core samples by decreasing the time required for conducting experiments. Moreover, it gets a better understanding of complex reservoir structures due to its ability ... -
Inverse Scattering Series internal multiple prediction through utilization of sparse transforms - Including high-performance implementational aspects
(Master thesis, 2018)Industry standard imaging algorithms do not treat internal multiples correctly. 'Cross-talk' with primary reflections may therefore occur in the imaging procedure, potentially causing significant artifacts in the image of ... -
Investigating Load Arches and the Uplift Capacity of Rock Anchors: A Numerical Approach
(Journal article; Peer reviewed, 2024)Rock anchors, which can withstand substantial forces and are essential for securing the foundations of the built environment, can fail due to steel tensile failure, bond detachment, or rock mass fracturing through uplift. ... -
Investigating the Effects of Carbon Dioxide Injection for Enhanced Oil Recovery - The Brent Group in the Statfjord Field
(Master thesis, 2018)According to the Norwegian Petroleum Directorate, the average oil recovery in fields on the Norwegian Continental Shelf is 47\%. Thus, more than half of the reserves are yet to be produced. CO2 injection is a method for ... -
Investigation of copper recovery from a new copper deposit (Nussir) in northern Norway
