Application of Extended Elastic Impedance (EEI) to improve Reservoir Characterization
Gharaee Shahri, Seyed Ali (Master thesis, 2013)The Extended Elastic Impedance (EEI) as a seismic attribute was first introduced by Whitcombe (2002) as a method for fluid and lithology prediction. EEI is the application of angle rotation in the conventional acoustic ... -
AVO Analysis of Turbidite Reservoir Rocks in the Alvheim Field
Eggen, Katharina Banschbach (Master thesis, 2012)The Alvheim reservoir is a turbidite reservoir, which means that the complex deposition makes it a difficult reservoir to perform predictions regarding reservoir content on. In the preceding project work (Eggen 2012) AVO ... -
AvO modelling constrained by burial history as an anomaly screening tool in complex geological settings.
Coronel Alvarez, Daniel Ricardo (Master thesis, 2020)AvO-teknologi har blitt anerkjent for å være sterkt påvirket av begravningshistorie. Siden bergartene som bygger opp mediet har registrert de forskjellige hendelsene og prosessene i strukturen sin, blir disse hendelsene ... -
Burial induced changes in physical sandstone properties: A case-study of North Sea and Norwegian Sea sandstone formations
Blazevic V., Lara A.; Duffaut, Kenneth; Avseth, Per Åge (Journal article; Peer reviewed, 2017)The changes in physical properties of sandstones with burial depth are a result of mechanical and chemical compaction processes. These processes are affected by rock microstructure, pressure regimes and temperature history. ... -
Effect of Curvature on Seismic Data and Amplitude Analysis: A Modeling Study
Heiebråten, Eivind Bøhn (Master thesis, 2014)The effect of curvature upon AVO-analysis and the capability of Kirchhoff time migration to remove these effects were investigated in this thesis. Curvature focuses or de-focuses seismic waves depending on the shape of the ... -
Integrating AVO, Seismic Inversion, and Rock Physics in Agua Fría 3D Seismic Cube
Gloria Lopez, Juan Carlos (Master thesis, 2014)Ten exploratory wells have been drilled in the Agua Fría area, led by amplitude anomalies and structural highs. Five of them resulted in dry wells and the other five in gas and oil discoveries. In some of these wells, water ... -
Machine learning assisted low-frequency model building for AVO inversion
Toloza Lara, Amaury Alejandro (Master thesis, 2018)AVO inversion is a valuable tool to estimate absolute reservoir properties from prestack seismic data. The bandwidth limitation of the seismic requires that the missing low frequencies must be added to the inversion in ... -
Modeling burial induced changes in physical sandstone properties - A case-study of North Sea and Norwegian Sea sandstone formations
Blazevic Vucelic, Lara Antonia (Master thesis, 2017)The changes in physical properties of sandstones with burial depth are a result of mechanical and chemical compaction processes. These processes are affected by rock microstructure, pressure regimes and temperature history. ... -
Quantitative interpretation using inverse rock-physics modeling on AVO data
Jensen, Erling Hugo; Johansen, Tor Arne; Avseth, Per Åge; Bredesen, Kenneth (Journal article; Peer reviewed, 2016)Quantitative seismic interpretation has become an important and critical technology for improved hydrocarbon exploration and production. However, this is typically a resource-demanding process that requires information ... -
Quantitative Seismic Interpretation using Rock Physics Templates - case examples from the Zumba field
Maulana, Taufik (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 Properties and Seismic Signatures of Hot Shales on the Norwegian Shelf
Fredriksen, Ida (Master thesis, 2013)Hot shales are made up of mainly clay, organic matter, silt and quartz, which cause hot shales to have a complex composition and texture. This makes it more advanced to do rock physics studies and AVO modeling. Complex ... -
Shale Rock Physics and AVO - Saturation and Pressure Effects on Shale Anisotrpic AVO
Alghenaim, Hamad (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 ... -
Well Log and Seismic Data Interpretation: Rock Physics Study of Poorly Consolidated Sandstones in The North Sea
Fanka, Walter Roye Taju (Master thesis, 2012)We use rock physics models for poorly consolidated rocks to diagnose reservoir sandstones in the Alvheim Field, North Sea. Geological factors that will control the rock physics and seismic properties include clay content, ...
