Estimating seabed velocities from normal modes
(Master thesis, 2012)In this Master Thesis a method for estimating seabed p-wave velocities from normal mode seismic data is developed. This is done through forward modeling using two dimensional finite difference modeling to generate synthetic ... -
Estimation of Anisotropy Parameters and AVO modeling of the Troll Field, North Sea
(Master thesis, 2012)In the work of this Master's thesis, the anisotropy parameters, epsilon and delta, for the reservoir and the cap rock on the Troll Field have been estimated. This was done using well logs from 35 wells, including the P-wave ... -
Experimental Study of Residual Gas Saturation using both Spontaneous and Forced Imbibition Method, where IsoparL is the Wetting Phase
(Master thesis, 2012)Today most of the oil is produced. This has triggered a wider interest for gas reservoirs. To determine how much gas that can be recovered in a reservoir it is important with good knowledge of the trapped gas saturation. ... -
Frostens utvikling mellom tunnel og bergmasse.: Felt- og laboratoriemålinger med WG Tunnelhvelv T100.
(Master thesis, 2012)I Norge er vinterkulden et problem i forbindelse med tunneldrift. I løpet av vinteren utsettes tunneler for frost i varierende grad, og det kan oppstå problemene med isdannelser som utgjør en trussel for sikkerheten og ... -
Gel Evolution in Oil Based Drilling Fluids
(Master thesis, 2012)Drilling fluids make up an essential part of the drilling operation. Successful drilling operations rely on adequate drilling fluid quality. With the development of new drilling techniques such as long deviated sections ... -
Gelling
(Master thesis, 2012)Today wells are drilled in deeper and colder water. If the circulation is stopped and the drilling fluid is at rest, most drilling fluids will develop gel strength. In colder water the gel strength becomes higher. To resume ... -
Global Optimization and Inital Models In Seismic Pre-Stack Inversion
(Master thesis, 2012)Abstract Pre stack inversion of seismic data consists of numerous difficulties. Two of the problems of greatest concern are the problems of non-uniqueness and non-linearity of the inversion. There may exist several solutions ... -
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 ... -
Human related root causes behind oil well drilling accidents
(Master thesis, 2012)Many accident investigation techniques and other methods used by the petroleum industry today list a set of underlying human related causes and subsequent improvement suggestions. Do these techniques address the root cause ... -
Hydrocarbon generation and migration from Jurassic source rocks in the northern North Sea
(Master thesis, 2012)Hydrocarbon generation and migration modelling from the northern North Sea -
Improved drilling process through the determination of hardness and lithology boundaries
(Master thesis, 2012)The main objective of drilling a well is the potential economic profit. The total cost of a drilling operation result from a complex interplay of many factors (Graham and Muench, 1959). Work that can optimize some of these ... -
Lab for heave motion during Managed Pressure Drilling
(Master thesis, 2012)A significant part of the world's remaining oil and gas prospects are challenging or impossible to reach by conventional methods. Examples are deep-water environments and depleted reservoirs with a narrow drilling window, ... -
Lab For Heave Motion During Managed Pressure Drillintg
(Master thesis, 2012)A significant part of the remaining oil and gas resources are present in harsh offshore environments and depleted reservoirs that are challenging to reach with conventional drilling methods. An ever increasing energy demand ... -
Maintaining well integrity during slot recovery operations
(Master thesis, 2012)The temporary plug and abandonment (P&A) of old wells, and the following slot recovery, will be important for increasing the average rate of recovery from the Norwegian Continental Shelf (NCS). However, these operations ... -
Managing pressure during underbalanced drilling
(Master thesis, 2012)AbstractUnderbalanced drilling has received more and more attention in recent years. The reason for that may be because many oil fields, especially on the Norwegian continental shelf, have started to show signs of aging. ... -
Methods of Pore Pressure Detection from Real-time Drilling Data
(Master thesis, 2012)The knowledge of formation pore pressure, and how it changes throughout the length of a well, is crucial in terms of maintaining control of the wellbore. Failure to recognize deviations from the expected pressures can lead ... -
Migration Study of the Uranus Prospect in the Barents Sea: Evaluation of Velocity Sensitivity, Wave Equation Migration and Acquisition Geometry
(Master thesis, 2012)Imaging of salt is a known geophysical challenge, since salt has complex geology, with varying lithology and complicated structures. Salt diapir can have steep dips and obtaining a correct velocity models are some of the ... -
Modeling wax thickness in single-phase turbulent flow
(Master thesis, 2012)Oil and gas transport is today a vital part of the industry. Oil cooled during transport in pipelines may precipitate paraffin wax. Precipitated wax may deposit on pipe walls and cause flow restrictions. Deposition models ... -
Modellering av YPL Fluid Strømning i Eksentrisk Annulus med Borestrengsrotasjon
(Master thesis, 2012)Denne oppgaven omhandler teoretisk modellering av trykktap grunnet rotasjon i eksentriske borehull med Herschel-Bulkley strømning. En eksisterende modell for trykktap for konsentriske borehull ble videreført til å inkorporere ... -
Modelling of Paraffin Wax in Oil Pipelines
(Master thesis, 2012)As warm oil or condensate from the reservoir flow through a pipeline on the cold sea bottom, wax often precipitate and deposit on the wall. To predict the rate of the deposition, wax modeling is important. The main mechanism ...
