Predictive accuracy of data-driven solutions to the transient response of the drilling system
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-15)One of the utmost desires of the drilling industry is full drilling automation to minimize well construction cost, optimize well performance and many other advantages. Dynamical system modeling and control of complex systems ... -
Pressure Build-Up in Closed Wells During Kick Migration and Fluid Compressibility Effects
(Chapter, 2022)If a kick is migrating in a closed well, this will lead to pressures building up in the well. It has earlier been shown that for Non-Newtonian fluids, suspension effects will make it impossible to deduce a unique gas ... -
Prevention of loss of drilling fluids and formation damage when drilling through high permeability formations
(Bachelor thesis, 2023)In order to avoid kicks and the potential for a well blowout, it is necessary to maintain the drilling fluid pressure above the pore pressure of the formation. However, doing so may result in fluid loss due to the fluid ... -
