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 ... -
Riserless Drilling Systems
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011-06-14)As the oil and gas recoverables are getting more inaccessible and harder to procure, the worlds demand for petroleum resources are constantly increasing. This entails the oil industry to expose themselves towards more ... -
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, ... -
Rock physics models for Cenozoic siliciclastic sediments in the North Sea
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)The Norwegian North Sea is a huge and mature hydrocarbon province which has been mapped extensively since the discovery of oil and gas in the late 1960s. There is a numerous amount of data that is available for companies ... -
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 characterization of fault zones for use in fault facies reservoir models

Seismic characterization of lower cretaceous clastic wedges in the Tromsø Basin
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-16)In this study, seismic reflection, well logs and core data has been used to characterize Lower Cretaceous marine to deep marine syn-rift clastic wedges in the southwestern Barents Sea. The study area is situated on a faulted ... -
Seismic Characterization of Lower Cretaceous Clinoform Packages in the Fingerdupet Sub-basin, Southwestern Barents Sea
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-29)The three wells drilled in Fingerdjupet Sub-basin during the late 1980’s were abandoned as dry holes, resulting in little exploration interest in the sub-basin. This leaves the depositional history poorly understood, and ... -
Seismic imaging of salt-influenced compressional folds
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Fold-and-thrust belts (FTB) detaching on salt have a high potential for developing trap structures and host large oil and gas fields. Due to their high structural complexity and often low-quality seismic data, their ... -
Seismic imaging of salt-influenced extensional forced folding
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Extensional forced folds are formed by the presence of a ductile salt layer, decoupling the overlying folded strata from the underlying faulted strata. Hydrocarbons are generally trapped within secondary structures of ... -
Seismic Inversion for Fluid and Lithology Prediction of the Mikkel Field
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)This study includes structural interpretation of main key horizons in the study area. AVO modelling, seismic colored inversion and extended elastic impedance are performed to support the structural interpretation and to ... -
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 ... -
