Seismic stratigraphy and geomorphology of the chalk group of the central graben, north sea
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-29)The Ekofisk Field in the Southern part of the North Sea has been producing oil since its discovery in 1969 from naturally fractured chalk of the Late Cretaceous to Early Paleocene ages. This Chalk Group of the Norwegian ... -
Selection of Long or Short Production Casing on HPHT Wells
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)Drilling in high-pressure high-temperature (HPHT) wells present many economical, technical and operational challenges. The wells are usually located in deep water¬¬¬––where the total well cost and trip times are increased. ... -
Sensitivity analysis of factors affecting torque and drag modelling
(Master thesis, 2014-06-14)As the modern day extended reached wells are getting longer and more complex, the torque and drag is one of the restraining aspects for achieving the target depth. Torque and drag becomes a precarious issue, for example ... -
Sequence stratigraphic analysis of the Jurassic period on the Horda Platform, northern North Sea, using state-of-the-art 3D seismic interpretation- tools and methodologies
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-16)A sequence stratigraphic analysis of the Jurassic sequence on the Horda Platform is the main focus for this study. The analyzed interval comprises the stratigraphic record from three mega-sequences; the Base Cretaceous ... -
Setting plug & abandonment barriers with minimum removal of tubulars
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)The useful life of an offshore well is determined by the reserves which it contacts, the pressure support within the reservoir and the continued integrity of the wellbore. When a well has reached the end of its lifetime, ... -
Shale Gas Production - Modelling With Non-linear Flow Mechanisms
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Unconventional shale gas reservoirs are well known as a low permeable reservoirs so production study from such reservoirs is very complex. In recent years, by introducing new techniques such as of massive fracture and ... -
Shoe track drillout: analysis of factors affecting drilling efficiency
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)Shoe track is a space between casing or liner shoe and the uppermost collar, which keeps contaminated cement after cementing operation has been performed. This term is also used to describe the whole downhole cementing ... -
Silicate injection for IOR
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-07-13)This thesis is a literature study of sodium silicate as an enhanced oil recovery method. We will follow the steps from experiments conducted, simulations, and then actual field operations conducted in the Snorre field, ... -
Simulation - based assessment of drilling riser and its application for the Kara Sea region
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06)Drilling in Arctic offshore conditions is a very challenging for the oil industry. With an increase in drilling operations in these harsh environments, drilling riser requirements and limits have become more critical due ... -
Simulation and interpretation of well tests in pressure (stress) sensitive reservoirs with induced fractures
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)In the petroleum industry pressure (stress) dependent permeability is usually not considered in reservoir simulations. It’s often due to lack of laboratory and field data, which determines the level of pressure (stress) ... -
Simulation and Modelling of Injectivity during Pressurized Mud Cap Drilling with the AUSMV Numerical Scheme
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)Operation and drilling in highly fractured carbonate formations are associated with several challenges. Some of the main challenges include large/total losses of drilling fluids, loss of hydrostatic pressure and gas influxes. ... -
Simulation of a gas kick
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)In this paper a gas kick is simulated using a MatLab program for the purpose of showing several important phenomenons that occur during a gas kick. Pressure, flow rate in and out, fluid velocities and fluid fractions is ... -
Simulation of CO2 injectivity in a laboratory cylindrical-cone model
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)In this thesis the processes (caused by injection of carbon dioxide) - mainly migration of particles and dissolution and precipitation of carbonates - which cause changing of permeability (and consequently injectivity) are ... -
