Wellbore stability and rock mechanics study on the Ula field
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-20)In the years to come more challenging drilling conditions will occur when the last reserves need to be collected. More directional drilling will be used and good wellbore conditions will be necessary to make this possible. ... -
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. ... -
Wettability alteration in carbonates : the effect of water-soluble acids in crude oil and application of enzyme for wettability alteration
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)The objective of the project is defined in two phases. The first phase is to study the effect of oil composition and carboxylic acids in the crude oil on the wetting condition and wettability alteration process using ... -
Wettability alteration in carbonates: the effect of water-soluble carboxylic acids in crude oil
(Journal article; Peer reviewed; Doctoral thesis, 2010)Acidic components in crude oil influence the wetting condition through their effect on electrostatic interactions with the mineral surfaces. In this paper, we have extracted water-soluble acids from a crude oil with a high ... -
Wettability in chalk, effect of initial water saturation on the adsorption of polar oil components
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Experimental study of wettability alteration was aimed at three laboratory designated chalk material, collected from the same reservoir block, at different initial water saturations (0%, 10%, and 40%). Crude oil sample ...
