Rayleigh and Wood anomalies in the diffraction of acoustic waves from the periodically corrugated surface of an elastic medium
(Peer reviewed; Journal article, 2016)By the use of the Rayleigh method we have calculated the angular dependence of the reflectivity and the efficiencies of several other diffracted orders when the periodically corrugated surface of an isotropic elastic medium ... -
Reactive flow in chalk at reservoir temperature – Experiment and simulation
(Bachelor thesis, 2021)This thesis seeks to study how 0.219 M MgCl2 brine flooded through chalk cores at reservoir temperatures will chemically react when flooded through at various flowrates. We used two different chalk cores. The cores were ... -
REAL-TIME DATA DRIVEN ROP AND TORQUE MODELLING AND OPTIMIZATION USING MACHINE LEARNING
(Master thesis, 2021)Obtaining the maximum rate of penetration (ROP) is one of many techniques to reduce cost and Non-Productive Time (NPT) in drilling wells. Many parameters affect ROP, including hole cleaning, tooth wear, etc. The study was ... -
Real-Time Minimization of Mechanical Specific Energy with Multivariable Extremum Seeking
(Peer reviewed; Journal article, 2021)Drilling more efficiently and with less non-productive time (NPT) is one of the key enablers to reduce field development costs. In this work, we investigate the application of a data-driven optimization method called ... -
