Rock Breaking under Rolling TBM Disc Cutters in Hard Rock Conditions – Visualization and documentation of cracks
(Doctoral theses at NTNU;2019:100, Doctoral thesis, 2019)Tunneler kan drives med boring og sprengning eller ved bruk av en tunnelboremaskin (TBM). Tunneboremaskinen har et roterende sirkulært hode med påmonterte kuttere av stål og kalles kutterhodet. Berget brytes ved at kutterene ... -
Rock Classification Using Multivariate Analysis of Measurement While Drilling Data: Towards a Better Sampling Strategy
(Journal article; Peer reviewed, 2018)Measurement while drilling (MWD) data are gathered during drilling operations and can provide information about the strength of the rock penetrated by the boreholes. In this paper MWD data from a marble open-pit operation ... -
Rock cut slope excavated for Settling basins of Seti Khola Hydropower Project
(Chapter, 2023)Stability of a cut-slope at the headworks area of the hydropower projects is very important for smooth operation of hydropower plant. Underestimation during construction period may bring a catastrophic consequence. This ... -
Rock mechanical analysis of underground caverns at Shatin wastewater facility
(Master thesis, 2017)This master thesis Rock mechanical analysis of underground caverns at Shatin Wastewater facility is written to evaluate the stability of the planned facility, based on the design and layout at the feasibility study level. ... -
Rock Mechanical Anisotropy, and its Impact on Borehole Stability
(Master thesis, 2014)In drilling operations, small margins between wellbore collapse and hydraulicfracturing can become aggravated in anisotropic formations. A stuck piperesulting from borehole failure can give serious economic consequences, ... -

Rock physics and AVO studies of PL 348 (Norwegian Sea)
(Master thesis, 2010)The block, PL 348 is situated on the Halten Area in the Norwegian Sea. This license contains four discoveries Galtvort, Galtvort South, Gygrid and Tau and number of potential prospects that bear similar AVO anomalies on ... -
Rock physics assessment of overburden stratigraphic sequences in the offshore Rovuma Basin, East African margin
(Doctoral theses at NTNU;2021:258, Doctoral thesis, 2021)The overall goal of this PhD research is to investigate production planning and control challenges in the semi-process industry and to develop an approach for addressing these challenges based on lean production and Industry ... -
Rock Physics Calibration for Ensemble Based 4D Seismic History Matching
(Master thesis, 2018)To model the future of a complex system, it is first necessary to be able to model the past. Accurate and efficient reservoir modeling is crucial for production forecasting and reservoir development. In this work the ... -
Rock physics depth trend analysis using seismic stacking velocity
(Master thesis, 2006)Quantitative seismic interpretation is becoming more and more important in exploration and characterization of petroleum reservoirs. In this technology, rock physic analysis combined with seismic attributes has become a ... -
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 ... -
Rock Physics Inversion for CO2 Saturation Estimation at Sleipner - Sensitivity Tests and Baseline Application
(Chapter, 2017)We demonstrate the use of rock physics inversion for estimating CO2 saturation and rock frame properties at the Sleipner CO2 storage pilot in the North Sea. We investigate the relation between rock physics properties and ... -
Rock physics model of shale: Predictive aspect
(Peer reviewed; Journal article, 2021)Shales often show strong elastic anisotropy that originate from the alignment and platy nature of its constituent minerals. Despite its impact on AVO (Amplitude Variation with Offset) response and seismic time-shifts, ... -
Rock Physics of extensional Faults and their seismic imaging Properties
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:113, Doctoral thesis, 2004)Seismic waves will detect changes in density and velocity, and potentially additional information with respond to these parameters will be useful for the seismic imaging of the Earth. Knowledge of faults and fault systems ... -
Rock Physics Properties and Seismic Signatures of Hot Shales on the Norwegian Shelf
(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 ... -
Rock Physics Templates from Deviated Wells using Anisotropy Parameters
(Master thesis, 2011)Rock physics templates (RPTs) are locally constrained charts that provide information regarding lithology and fluid saturation encountered at an area of interest. Normally anisotropy is neglected and isotropy is prevalent ... -
Rock Properties in Synthetic- and Natural Clay Materials - An Experimental Study on Shale Barrier Materials
(Master thesis, 2018)Since the late 1960's, thousands of wells have been drilled on the Norwegian Continental Shelf (NCS) - following the discovery of large hydrocarbon reserves on what eventually became Norwegian territory in the North Sea. ... -
