Evaluation of artificial lift methods on the Gyda field
(Masteroppgave/UIS-TN-IPT/2009, Master thesis, 2009)Since a production peak in 1995 the oil production on the Gyda field has decreased. Water cut is increasing and reservoir pressure is decreasing. This thesis is a study of the artificial lift methods being evaluated to ... -
Evaluation of Cellulose Nanocrystals as a Green "Smart Water" Additive in Enhanced Oil Recovery from Sandstone Reservoirs
(PhD thesis UiS;348, Doctoral thesis, 2017-06-15)Petroleum reservoir production is frequently supported by using flooding fluids, and offshore this fluid will very often be seawater. The efficiency of this water injection is affected by various factors, such as the ... -
Evaluation of Downhole Tubing Disposal for Permanent Plug and Abandonment
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)A new method called Downhole Tubing Disposal developed by Oilfield Innovations for performing rigless permanent plug and abandonment is presented. Instead of pulling the production tubing, the tubing is weakened with ... -
Evaluation of experimental methods to determine wettability
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)Two methods to evaluate the wettability of carbonates have been investigated: Aqueous cationic surfactant solutions contact angles on oil-wet calcite crystals, and imbibition time of surfactant drops into oil-wet ... -
Evaluation of Foam Cementing the Reservoir Liner in Deviated Wells on the Ekofisk M Platform
(Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)Foam cementing the reservoir liner has proven to be a good solution for achieving zonal isolation due to its low permeability and high compressive strength. However, out of the 32 reservoir liners cemented on the Ekofisk ... -
Evaluation of hydro acoustic condition monitoring of subsea processing equipment
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)The project described in this thesis is based on the perceived fact that a need for advancements in monitoring technology results from the development of more complex subsea equipment. An existing type of hydro acoustic ... -
Evaluation of kick and loss scenarios in experimental lab facility
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Detection and evaluation of gain and loss situations is crucial for safety during drilling operations. During managed pressure drilling there is higher risk of kicks than during traditional drilling. Early stage detection ... -
Evaluation of low salinity injection EOR potential in Johan Sverdrup Field
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017)Low salinity waterflooding is an EOR method that doesn’t get mentioned as much as other EOR methods in the current oil industry, but its recognition has been raised in the last few years and BP is also using their own low ... -
Evaluation of Measurement-While-Drilling, telemetry methods and integration of control systems
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)This paper will present an overview of the applications of the measurements performed by the Measurement-While-Drilling and Logging-While-Drilling tools. An evaluation of the available telemetry techniques used to transfer ... -
Evaluation of silicate and polymer systems for disproportionate permeability reduction in oil reservoirs
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)The main objective of this work is to screen and evaluate various commercially existing polymers and silicate systems mixed with crosslinkers and/or activators for their gel-forming capabilities for the water management ... -
Evaluation of strategies for fracture modeling: A case study at Teapot Dome, Wyoming
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)The characterization of fractured reservoirs is complex. Fracture modeling is often based on very limited well data and therefore is subject to high uncertainty. Typically, the standard modeling workflow uses interpolation ... -
Evaluation of the compositional changes during flooding of reactive fluids using scanning electron microscopy, nano-secondary ion mass spectrometry, x-ray diffraction, and whole-rock geochemistry
(Journal article; Peer reviewed, 2015-05)Outcrop chalk of late Campanian age (Gulpen Formation) from Liège (Belgium) was flooded with MgCl2 in a triaxial cell for 516 days under reservoir conditions to understand how the non-equilibrium nature of the fluids altered ... -
Evaluation of the primary cement operation on the production casing in the Ekofisk field and the Eldfisk field
(Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)The foremost goal of primary cementing is to provide zonal isolation in a well. Cementing of the casing/liner set right above the reservoir on the Ekofisk and Eldfisk fields are associated with a lot of challenges. ... -
Evaluation of the “Command Take-Over Procedure” in automated well control
(Master thesis, 2014-06-13)The growing need for new technology in the pursuit of oil is creating new challenges related to well control. Drilling in HPHT (High Pressure High Temperature) reservoirs, arctic areas, and depleted zones might imply ... -
Evaluation of using Smart Water to enhance oil recovery from Norwegian Continental Shelf sandstone reservoirs.
(Master thesis, 2016-06-09)Recently, the scale of studies on smart water – one of EOR method - has increased. From decades, water flooding is one of the most used methods to increase oil recovery. However, more effective in sandstone reservoirs is ... -
Evaluation of WAG injection at Ekofisk
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)In the North Sea many fields are water flooded. Subsequent to water flooding large amounts of water flood residual oil will be left in reservoirs. The challenge is how to improve the oil recovery. On the Ekofisk field such ... -
