Particle settling in non-Newtonian drilling fluids
(PhD thesis UiS;80, Doctoral thesis, 2009-12-14)Particle settling is relevant for several aspects of drilling and completion operations, and is directly related to safety and operational efficiency. The primary function of particles added to drilling fluids is to ... -
Pore scale modeling of capillary pressure curves in 2D rock images
(PhD thesis UiS;213, Doctoral thesis, 2013-12-10)Capillary pressure is relevant to most processes of multiphase flow inporous media, as it controls the pore scale fluids distribution. Reliable capillary pressure curves are required to model and predict larger-scale ... -

Seismic Imaging of Fault Zones : A synthetic workflow to study the impact of faults on seismic images
(PhD thesis UiS;293, Doctoral thesis, 2016-06-02)Although typically interpreted as 2D surfaces, faults are 3D narrow zones of highly and heterogeneously strained rocks with petrophysical properties differing from the host rock. Fault zones have been extensively studied ... -
Use of successive pressure build-up test data from well A-1 H in the Snadd field to obtain dynamic reservoir information
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-07)Well A-1 H in the Snadd field was put on test production at the beginning of 2013. Since then, a series of pressure build-up tests has been conducted. These aimed to allow the evaluation of the quality of the Lysing prospect ... -
Water weakening of chalk: A mechanistic study
(PhD thesis UiS;11, Doctoral thesis, 2005)Since the detection of the Ekofisk subsidence some 20 years ago, there has been a considerable research activity concerning chalk behaviour in general, and mechanical properties particularly. Due to the importance of water ... -
Water-Based EOR in Limestone by Smart Water : A study of surface chemistry
(PhD thesis UiS;147, Doctoral thesis, 2011-12-09) -
Waterflooding of carbonate reservoirs : EOR by wettability alteration
(PhD thesis UiS;50, Doctoral thesis, 2008-05-30)Oil production is generally divided into three stages, primary recovery, secondary recovery and tertiary recovery. In primary recovery, which is usually (but not necessarily) the first production stage, the natural energy ... -
Wellhead Fatigue Analysis : Surface casing cement boundary condition for subsea wellhead fatigue analytical models
(;163, Doctoral thesis, 2012-05-31)Material fatigue is a failure mode that has been known to researchers and engineers since the 19th century. Catastrophic accidents have happened due to fatigue failures of structures, machinery and transport vehicles. ...
