Crustal Stress Heterogeneity in the Vicinity of a Geothermal Field: Coso Geothermal Field, CA
Borehole induced structures seen in image logs from the Coso Geothermal Field, CA record variation in the azimuth of principal stress. Image logs of these structures from five boreholes were analyzed to quantify the stress heterogeneity for three geologically distinct locations: two boreholes …

Seismic Characterization of Faults from 3-D Seismic Data: Fault Detection, and Characterization of the Bakken Formation
… fault orientations correlate with borehole image logs in horizontal wells. Crossing conjugate faults observed on the fault-dip attribute are interpreted to result in widening of the faulted area and localized thinning of the rock sequence at the intersection of conjugate faults. This fault …

Mechanical stratigraphy of the Vaca Muerta Formation, Neuquén Basin, Argentina
… in a study area consisting of 5 wells. Borehole image logs were interpreted to study pre-existing natural fractures, and a stability assessment was conducted to estimate the reactivation potential of the identified natural fractures. The comparison results in the characterization of an interval …

Influence of topographic stress on rock fracture : a two-dimensional numerical model for arbitrary surface topography and comparisons with borehole observations
… profiles of Cmin with structural analyses of image logs from four boreholes located on the valley floor, and find that fracture abundance declines sharply with depth in the uppermost 10 m of the boreholes, consistent with the modeled profile of Cm.. In contrast, Cmin increases with depth below …

Structural and stratigraphic controls on fracture distribution within sand bodies of the Upper Iles and Lower Williams Fork formations, Mamm Creek and Divide Creek fields, Piceance Basin, Colorado
… the Mamm Creek field through the use of Borehole Image Logs, electrical logs, and outcrop. Sand bodies were divided into 5 different facies associations for fracture analysis, in order to investigate the stratigraphic controls on fracture properties. Positive linear relationships were identified …

The 3D in-situ stress field and its changes in geothermal reservoirs
… with 495 data records. Therefore, I analysed image logs from 57 boreholes in Iceland for indicators of the orientation of the maximum horizontal stress component. The study is the first stress survey from different kinds of stress indicators in a geologically very young and tectonically active …

Faults and fractures in the Niobrara Formation of Wattenberg field, Colorado
… as linear amplitude discontinuities. Borehole image log scale faults show displacement. Borehole image log scale fractures do not show displacement. Both borehole image log scale faults and fractures are interpreted as seismic-scale fractures. Faults were discovered by interpreting inflection …

Architecture of fluvio-deltaic sandbodies: the Namurian of Co. Clare, Ireland, as an analogue for the Plio-Pleistocene of the Nile Delta
… in outcrop (Co. Clare) and interpreted from image logs (Nile Delta) show similar facies and sedimentary successions in the two systems, improving confidence in the choice of analogue. Fieldwork carried out on the Upper Carboniferous (Namurian) coastal outcrops of Co. Clare produced detailed …

Quantification of rock fabric through multi-scale image data analysis for enhanced rock typing and formation evaluation
… through qualitative interpretation of core image data. The identified facies are frequently employed in the development of geological models. However, conventional methods for facies identification can be subjective, qualitative, and time-consuming. Only the visual aspect of the core, when …
