Petrophysical Evaluation of a Shaly Sand Reservoir- A Case study of exploration well 7220/8-1 from the Barents Sea, Norway
(Master thesis, 2015)This study is based on well data from the exploration well 7220/8-1 in the Barents Sea, Norway located at NS degrees 72° 29' 28.92'' N, EW degrees 20° 20' 2.25'' E, NS UTM [m] 8051910.71 and EW UTM [m] 678908.52 at UTM ... -
Pore pressure prediction ahead of the drill bit using Borehole Seismic Data.
(Master thesis, 2014)Knowledge of the formation pore pressure is fundamental to maintaining safety and control of the borehole during drilling operations. Non-hydrostatic pressures can cause blowouts and borehole instability and when they are ... -
Quantitative Seismic Interpretation using Rock Physics Templates - case examples from the Zumba field
(Master thesis, 2016)A post drill inversion study was done by Avseth et al. (2016) after the dry well result from Zumba prospect. The AVO inversion failed in a graben setting, caused by a hard carbonate layer and associated refraction just ... -
Rock physics inversion for CO2 characterization at Sleipner
(Master thesis, 2017)We combine Full-Waveform Inversion (FWI) and rock physics inversion to provide quantitative estimates of CO2 saturation at Sleipner. The rock physics tool is based on uniform saturation and patchy saturation rock physics ... -
Saturations Calculations Using Saturation-Height Modeling on the Well Mariana, offshore Lower Congo Basin - Saturation Height approachs
(Master thesis, 2015)Saturations calculations have been, for many years, object of high importance for the oil industry. Many literatures show different empirical and scientific efforts to produce robust saturations functions which attempt to ... -
Seismic data interpretation of the Snøhvit gas field - .
(Master thesis, 2016)In this work, 3D seismic and well data are used for mapping the Snøhvit reservoir and modelling the hydrocarbon column through Petrel software. The reservoir mapping procedure consisted in interpreting horizons, faults and ... -
Seismic Dispersion in Pierre Shale
(Master thesis, 2015)In applied geophysics, there is a trend to progress from a qualitative interpretation towards a quantitative interpretation.4D seismic (time-lapse seismic) is a common tool used in reservoir characterization, by which we ... -
Seismic Expression of Deep-Water Fan with an Example from Triassic in Southwestern Barents Sea
(Master thesis, 2014)Generation of high-quality 3D seismic data and easy access to this data across the deepwater environments together with the prior interest of oil companies in the deep-water exploration has attracted geoscientists to the ... -
Seismic Facies Analysis and Geomorphology Study of Deep Water Channel Complexes in Lower Congo Basin, Offshore Angola
(Master thesis, 2015)Deep water channels that resulted from turbidity currents are very common offshore West Africa. Turbidite currents have formed also channel complexes along the Lower Congo Basin, Offshore Angola. Turbidite channels are ... -
Seismic interpretation and characterization of hydrothermal vents and vertical fluid-flow conduits in the Naglfar Dome (Vøring Basin, Norwegian Sea).
(Master thesis, 2017)Seismic interpretation, attribute analysis and statistical analysis were used to interpret and analyse the hydrothermal vents and conduits in the Naglfar Dome, Vøring Basin. -
Seismic Interpretation and Characterization of the North Sea Chalk Group
(Master thesis, 2015)The types and properties of the Chalk Group in the North Sea have been sparingly studied from seismic dataset. This study is aimed at investigating the depositional settings and physical properties of the Cretaceous Chalk ... -
Seismic Stratigraphic Interpretation of Late Palaeozoic Carbonates and Paleogeography of the Loppa High.
(Master thesis, 2016)This thesis presents a detailed study of Late Palaeozoic stratigraphic successions on the Loppa High using seismic 2D and 3D data and well logs. Four intervals of interest have been mapped using carbonate stratigraphy ... -
Seismic Wave Attenuation in Partially Saturated Sandstone and AVO Analysis for Carbon Dioxide Quantification at Sleipner
(Master thesis, 2017)Sleipner field (North Sea) is the first largest CO2 storage site, where the Carbon Dioxide is reinjected into the Utsira Sandstone. The main aim of this work is to obtain an estimate of the CO2 saturation by using AVO ... -
Shale Rock Physics and AVO - Saturation and Pressure Effects on Shale Anisotrpic AVO
(Master thesis, 2015)AVO sensitivity analysis was performed on Mancos Shale data to study the effect of stress and saturation on shale reservoirs. All the data was collected for seismic and ultrasonic frequencies and dispersion seem to be an ... -
Shaly Sand Formation Evaluation from logs of the Skrugard well, Southwestern Barents Sea, Norway
(Master thesis, 2016)The use of Archie interpretation model to estimate water saturation in clean formation has successfully been useful over the years. However, in shaly sand formation this model yields inaccurate S_w estimates (overestimate) ... -
