A novel model-based scheme for kick and loss mitigation during drilling
Hauge, Espen; Aamo, Ole Morten; Godhavn, John-Morten; Nygaard, Olav Gerhard Haukenes (Journal article; Peer reviewed, 2013)A model-based in-/out-flux detection scheme for managed pressure drilling is presented. We apply a globally exponentially stable adaptive observer which estimates the unknown states and parameters of the hydraulic system ... -
Advanced leak detection in oil and gas pipelines using a nonlinear observer and OLGA models
Hauge, Espen (Master thesis, 2007)An adaptive Luenberger-type observer with the purpose of locating and quantifying leakages is presented. The observer only needs measurements of velocity and temperature at the inlet and pressure at the outlet to function. ... -
Automatic Kick Detection and Handling in Managed Pressure Drilling Systems
Hauge, Espen (Doktoravhandlinger ved NTNU, 1503-8181; 2013:88, Doctoral thesis, 2013) -
Design and Experimental Validation of Nonlinear Infinite-Dimensional Adaptive Observer in Automated Managed Pressure Drilling
Hasan, Agus Ismail; Imsland, Lars Struen; Hauge, Espen (Journal article; Peer reviewed, 2017)Utilizing flow rate and pressure data in and out of the fluid circulation loop provides a driller with real-time trends for early detection of well-control problems that impact the drilling efficiency. Due to limited number ... -
Dynamic Simulation of Gas Expansion in Marine Risers
Velmurugan, Naveen (Master thesis, 2016)The main objective of the work is to study the dynamic behavior of gas expansion in marine risers. In case of well control situations in deep and ultra deep waters, gas influx shows no warnings if not little, making it ... -
Managed Pressure Cementing
Meneses Pereira da Silva, Joao Francisco da Cunha (Master thesis, 2015)Managed Pressure Cementing (MPC) is a method to cement deep offshore wells in a safer, more controlled and more efficient way. It will end up being less costly because by applying managed pressure drilling (MPD) first the ... -
MPC for dual gradient borebrønnkontroll ved hjelp av en undervannspumpemodul og en topside strupeventil
Magnus, Andreas (Master thesis, 2014)Denne avhandlingen undersøker hvor godt en lineær MPC med dynamiske modeller kan kontrollere bunnhullstrykket (BHP) når et dual-gradient boresystem (DGD) utsettes for gass-kick. MPC-en anvender en riggpumpe, undervannspumpemodul ... -
State and parameter identification applied to dual gradient drilling with oil based mud
Slettebø, Dag (Master thesis, 2015)Dual gradient drilling (DGD) is a modern technology that allows for drilling wells for oil and gas in a more precise and efficient manner. Many of the future oil and gas prospects are highly complex and challenging with ... -
State and Parameter Identification Applied to Dual Gradient Drilling with Water Based Mud
Haukanes, Simon (Master thesis, 2015)There is a continuous search for new reserves in the oil and gas industry. Most of the larger fields that are accessible with conventional drilling technology have been drilled. The remaining fields typically contain less ...
