High-Temperature Core Flood Investigation of Nanocellulose as a Green Additive for Enhanced Oil Recovery
(Journal article; Peer reviewed, 2019)Recent studies have discovered a substantial viscosity increase of aqueous cellulose nanocrystal (CNC) dispersions upon heat aging at temperatures above 90 °C. This distinct change in material properties at very low ... -
Higher-order Hamilton–Jacobi perturbation theory for anisotropic heterogeneous media: dynamic ray tracing in Cartesian coordinates
(Journal article; Peer reviewed, 2019)With a Hamilton–Jacobi equation in Cartesian coordinates as a starting point, it is common to use a system of ordinary differential equations describing the continuation of first-order derivatives of phase-space perturbations ... -
Himalayan rock mass and possibility of limiting concrete lined pressure tunnel length in hydropower projects in the Himalaya
(Journal article; Peer reviewed, 2015)In recent past, the development activity in hydropower sector got momentum in the Himalayan region. However, the investment cost is considered considerably higher than in other part of the world, and there is a strong need ... -
History Matching a Full Field Reservoir Simulation Model - The Jette Field
(Master thesis, 2014)Reservoir models are used for understanding and prediction of reservoir performance. The Jette dynamic reservoir model were not capable of representing reservoir performance at Jette and experienced problems with prediction ... -
History Matching and Production Performance Prediction of the Norne Field
(Master thesis, 2019)Reservoir simulation effectiveness depend so much on the reliability of the model which is worked upon. Reliability of the model depend on the amount of information engineers have about the reservoir which is been modeled, ... -
History Matching and Uncertainty Assessment of the Norne Field E-Segment Using Petrel RE
(Master thesis, 2010)History matching is one of the most important activities during the development and management of petroleum reservoirs. Matched models are fundamental to ensure reliable future forecasts, and give an idea of the level of ... -
History Matching of Production and 4D Seismic Data: - Application to the Norne Field
(Master thesis, 2014)History matching is the procedure to build a model as close as possible to nature. Reservoir models, constrained to seismic response, as well as flow response, can provide a better description of the reservoir and thus ... -
History Matching of South Gullfaks Field-A Holistic Approach
(Master thesis, 2010) -
History matching of the Norne field
(Master thesis, 2010)History matching is an inverse problem with several possible solutions. The degree of nonuniqueness reduces when seismic observation data becomes incorporated. This thesis contains a history match of the Norwegian Sea oil ... -
History matching of the Norne Field using the Ensemble based Reservoir Tool (EnKF/ES)
(Master thesis, 2014)In this thesis two stochastic algorithms, the Ensemble Smoother (ES) and the Ensem-ble Kalman Filter (EnKF), have been utilized as automatic history matching meth-ods through the Statoil developed program the Ensemble based ... -
History Matching of Vertical Gas Injection Displacement Experiments
(Master thesis, 2018)This master thesis presents simulations of two core flooding experiments. The two experiments consisted of injecting gas in a gravity stablemanner into a vertical core, after the core had beenwaterflooded. The main difference ... -
History Matching with the use of Qualitative 4D Seismic Data Application to Norne Field
(Master thesis, 2016)History matching is a very important activity performed in reservoir management since it helps to improve and validate reservoir simulation model and hence obtain reliable reservoir performance forecast. History matching ... -
History Matching, Forecasting & Production Optimization on Norne E-Segment
(Master thesis, 2012)I performed manual History Matching on the E-segment of the Norne field based on available production & pressure data. I used the obtained final match for future prediction. I performed Production Optimization by experimenting ... -
History Matching: Effekten av tilgjengelig informasjon
(Master thesis, 2012)En god reservoarmodell, som både representerer de statiske parameterne og strømningsegenskaper, er avgjørende for å optimalisere produksjonen fra hvilket som helst reservoar. Mye tid og krefter blir brukt til å beskrive ... -
Hole Cleaning and Mechanical Friction in Non-Circular Wellbore Geometry
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:88, Doctoral thesis, 2014)Drilling is one of the most important cost drivers in the finding and development of oil and gas fields. More efficient drilling reduces the overall costs and enables drilling of longer wells to reach new reservoir targets. ... -
Hole cleaning efficiency of sweeping pills in horizontal wells
(Master thesis, 2019)Dårlig hullrensing er årsaken bak mange alvorlige boreproblemer som utfordrer planlagt operasjonstid og budsjettramme for både vertikale og horisontale brønner. Vanlig praksis er å bruke såkalte sweeping pills som rensemiddel ... -
Hole-cleaning performance comparison of oil-based and water-based drilling fluids
(Journal article, 2017)Cuttings transport is a topic of great interest in the oil and gas drilling industry. Insufficient cuttings transport leads to several expensive problems. Knowledge and selection of the drilling fluids is one of the important ... -
Holistic flow and pressure control for underbalanced drilling operations
(Doctoral theses at NTNU;2016:333, Doctoral thesis, 2016)This text is targeted towards engineers and researchers working with drilling automation. Though the selected application domain is underbalanced drilling (UBD) the results are applicable to managed pressure drilling ... -
Holmestrand Underground Railway Station - Analysis of Groundwater Inflow and Methods for Water Sealing
(Master thesis, 2012)The planned new railway station in Holmestrand whose location will be inside a basalt plateau poses challenges concerning the grouting and water and frost protection. Based on grouting works in adjacent tunnels Snekkestad ... -
