Rig integrated managed pressure drilling
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-05)The complexity and challenges related to drilling of wells shows an increasing trend, and there is a demand for new technology and/or methods. Managed pressure drilling (MPD) is gaining more and more attention on the market, ... -
Riserless drilling (managed pressure drilling)
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)There are several problems which an oil and gas industry is facing. These problems can be solved by riserless drilling method which comes under managed pressure drilling umbrella. The most important problem is increasing ... -
Risk based cost and duration estimation of permanent plug and abandonment operation in subsea exploration wells
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)World wide there are thousands of subsea wells to be abandoned, including the subsea wells in the North Sea. The operation to abandon a well is commonly known as Plug and Abandonment or P&A. Traditionally for offshore ... -
Risk based cost and duration estimation of well operations
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Due to high uncertainties and the cost intensive nature of well operations, accurate forecast of well cost and duration is one of the main requirements for writing an AFE and supporting decision making processes. Traditionally, ... -
ROP modelling and analysis
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-11)A total of six techniques are developed to model ROP for a new well. The techniques attain coefficients or specific values from a close-by already drilled well. Using these and drilling parameters, the proposed method ... -
ROP optimization and modelling in directional drilling process
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-01)Rate of penetration (ROP) is one of the most critical parameters affecting virtually all drilling characteristics including technical, operational, economical, safety and other aspects of it. ROP evaluation may provide ... -
Sand Control Selection in HPHT Reservoirs
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-07)High Pressure High Temperature (HPHT) reservoirs have shown to have great potential of oil and gas reserves through industrial experience. Norwegian Continental Shelf has such good potential HPHT reservoirs. But, HPHT ... -
Screening of zonal isolation agents for SAGD EOR applications
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Utilization of Steam Assisted Gravity Drainage (SAGD) features is currently one of the most widely applied technologies for production of bitumen oil in Canadian oil sand fields. However, as in most oil and gas reservoirs, ... -
Section milling during plug and abandonment of petroleum wells
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)During plug and abandonment (P&A) operations of petroleum wells there is often a need to remove casing in order to set competent barrier sealing in all directions. If the casing cannot be cut and pulled, a section milling ... -
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 ... -
Seismic Reservoir Characterization: Norwegian Sea, Norway
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)A three step work flow seismic reservoir characterization method, comprised of the extended elastic impedance, coloured inversion and net pay estimation was tested in a data obtained from the western part of the deep water ... -
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 ... -
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
