Micro-Testing While Drilling for Rate of Penetration Optimization: Experiments and Simulations
Nystad, Magnus Edvard; Aadnøy, Bernt Sigve; Pavlov, Alexey (Peer reviewed; Journal article, 2021)The rate of penetration (ROP) is one of the key parameters related to the efficiency of the drilling process. Within the confines of operational limits, the drilling parameters affecting the ROP should be optimized to drill ... -
Minimizing Risk by Determining A Safe Mud Weight Window for Offshore Wellbore Construction
Khosravanian, Rasool; Aadnøy, Bernt Sigve (Journal article; Peer reviewed, 2020)Increased requirements for uncertainty analysis have caused a shift in sensitivity assessment, from a deterministic approach to a stochastic process. To ensure wellbore integrity, it’s essential to conduct breakout and ... -
Optimized Drilling Saves Time in the Persian Gulf
Khosravanian, Rasool; Aadnøy, Bernt Sigve (Peer reviewed; Journal article, 2020) -
Real-Time Data-Driven Drilling Optimization
Nystad, Magnus (Doctoral theses at NTNU;2021;348, Doctoral thesis, 2021)Drilling a well for exploration or production of petroleum resources is a costly and complicated procedure. There is a great potential for cost reduction by drilling safer, faster and with less Non-Productive Time (NPT). ... -
Real-Time Minimization of Mechanical Specific Energy with Multivariable Extremum Seeking
Nystad, Magnus; Aadnøy, Bernt Sigve; Pavlov, Alexey (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 ...
