A temperature model for Extended Reach Drilling applications
Langåker, Vebjørn (Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)Ensuring precise estimation of temperature is a critical process for well planning and real-time drilling operations, especially for Extended Reach Drilling (ERD). Therefore, a temperature model has been developed to predict ... -
Adaptive Observer Design for Linear Hyperbolic System in Managed Pressure Drilling
Kurnia, Hafiz (Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Managed Pressure Drilling (MPD) is a drilling technology that has been developed to manage and control the downhole pressure in the well in order to minimize drilling-related problems. This technology uses a pressurized ... -
An investigation into the heat transfer process in petroleum wells, and a comprehensive modeling study investigating the temperature distribution in production wells
Horpestad, Thomas (Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)When producing hot fluid from a reservoir, the production well experiences changing temperatures with depth for the different tubing, casing, cement and wellbore interfaces. To what extent the temperatures change is depending ... -
Automated MPD level in the oil and gas industry and development possibility
Majeed, Qassim Hameed (Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06)Automation is introduced to the industrial field long time ago, but still in its first steps in the oil and gas industry. There are many reasons led to this slow of automation in this industry. These reasons related to the ... -
Controller design for back pressure Managed Pressure Drilling when using oil based mud in long wells.
Nepal, Sima Alise (Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-14)In all drilling operations, downhole pressure requires to be closely monitored and measured at all times. Mainly, drilling fluid is used to balance the formation pressure downhole, a pressure that is created so that formation ... -
Drillbotics 2016: Management of drilling incidents while drilling heterogeneous formation rocks.
Alani, Omar (Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-29)The purpose of the thesis is to analyse the abnormal incidents on the drill pipe. The reason for this research is to apply the learned theories into the reality by building an automated rig and detect the problems. Also, ... -
Integration of modeling and drilling incident management of a real-time lab-scale autonomous drilling rig
Holsaeter, Andrew (Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-29)The basis of this thesis is an attempt to design, construct, and implement a fully autonomous lab scale drilling rig with real time optimization and capable of drilling detection and subsequent mitigation. Two simplified ... -
Investigation of temperature- and pressure effects on drilling fluid properties and related downhole torque and drag calculations
Tveiterå, Martin (Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Increasing temperature and pressure with depth, affects the properties of drilling fluid. The effect of temperature and pressure on the density and viscosity of drilling fluid is of great importance. This is because, among ... -
Rate of penetration optimization using moving horizon estimation
Sui, Dan; Aadnøy, Bernt Sigve (Journal article; Peer reviewed, 2016)Increase of drilling safety and reduction of drilling operation costs, especially improvement of drilling efficiency, are two important considerations in the oil and gas industry. The rate of penetration (ROP, alternatively ...
