A temperature model for Extended Reach Drilling applications
(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
(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 ... -
Characterization and performance study of OBM at various oil-water ratios
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015)Drilling fluids are an essential part of the drilling operation. One of the main functions of a properly maintained drilling fluid is to suspend cuttings, as well as weighting materials, in static conditions. Insufficient ... -
Drillbotics 2016: Management of drilling incidents while drilling heterogeneous formation rocks.
(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, ... -
Drilling an ERD Well on the Statfjord Field, North Sea
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-04-05)Old platforms are not well known for extended-reach drilling (ERD) operations mainly due to rig and hydraulics limitations. ERD wells demand robust rig capabilities, good hydraulics systems, and equipment reliability. In ... -
Dynamic Simulation Study on Alternative Marine Drilling Riser Materials in the Deep-Waters of the Norwegian Sea
(Master thesis, 2017-06-15)In the pursuit of more oil and gas to meet the growing demand and replace the declining production, the offshore industry is pushed to invest, explore and drill new wells in deeper waters with harsh environments and with ... -
Effect of Nano silica in brine treated PAC/XC/ LV-CMC polymer Bentonite fluid system
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06)In this thesis the performance of Nano silica in polymer based bentonite fluid system was analysed. Several combination of Nano with salt and polymer types were formulated and tested. The effect of temperature, salt, polymer ... -
Experimental Design and Setup of Circulation Flow Loop - Using Particle Image Velocimetry
(Master thesis, 2017-07-25)Mud left static in a well over a longer period of time can begin to gel up or form filter cakes along the formation wall and in washout zones, which can be difficult to remove. Therefore, proper mud mobilization and removal ... -
Futuristic Approach to Riserless Plug and Abandonment Operations
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-13)On the Norwegian Continental Shelf (NCS) today, there are 1033 subsea wells that are classified with the status online/operational, Drilling, Predrilled, Suspended and Closed[1] and these subsea wells will have to be ... -
How to apply a two-phase model from fluid mechanics to study cell migration mechanisms
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)The classical Keller-Segel model of cell migration due to random motion and chemotaxis, has, as a result of its intuitive simplicity and ability to replicate key behavior of chemotactic populations, provided a foundation ... -
Integration of modeling and drilling incident management of a real-time lab-scale autonomous drilling rig
(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 gas composition on production performance of J-shaped gas-lift well
(Master thesis, 2014-06-16)The J-shaped gas-lift well showed complex dynamic phenomena. The downward inclination of the J-shaped well introduces periodic waves over time as a result of mixing gas and liquid. This behavior introduces periodic ... -
Investigation of temperature- and pressure effects on drilling fluid properties and related downhole torque and drag calculations
(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 ... -
