We demonstrate statistically significant self-organized clustering over a length scale range from 10 −2 to 1 m for north-striking opening-mode fractures (joints) in Late Archean Mount Owen Quartz Monzonite. Spatial arrangement is critical fracture network attribute that until recently has only been assessed qualitatively. use normalized intensity plots and the correlation count (NCC) method of Marrett et al. discriminate clustered randomly placed or evenly spaced patterns quantitatively wide...
Shales commonly exhibit anisotropy in their elastic wave velocity, which directly impacts the accuracy of seismic imaging and geomechanical response to drilling completions. Anisotropy is often caused by mineralogical layering, fractures rock fabric (i.e. oriented grains intrinsic clay sediments). However, relative impact each these features on macroscopic shale properties not well understood. We combined scanning electron microscopy (SEM) X-ray microcomputed tomography image structural...
Sedimentary rocks contain layers and a wide range of microstructures that may produce mechanical complexities including dynamic quasistatic stiffness anisotropy nonlinearity. However, most applications in geophysics geomechanics disregard these complexities, which can lead to significant error uncertainty rock properties increase the risk associated with cost-intensive drilling completions operations shales. We have conducted simultaneous triaxial stress tests ultrasonic wave propagation...
Microfracturing and induced elastic anisotropy impart changes on body wave velocities with implications to seismic wellbore testing methods interpretation. We have conducted simultaneous triaxial stress tests ultrasonic propagation monitoring quantify S-wave microfracture development in Berea Sandstone Silurian Dolomite. The onset of stress-induced microfracturing is detected at the beginning appreciable called “S-wave crossover” (SWX). SWX subsequent increases evidence microstructural...
Abstract In over 300 expandable sand screen (ESS®) installations around the world it has proven exceedingly difficult to perform an equitable and rigorous comparison between open-hole ESS system alternative completion technique. this study, there is a marked apparent difference in performance systems investigated more detail order compare techniques on equal footing. The Mokoko Abana field situated offshore Cameroon. It mature heavy oil initially developed 1980s. unconsolidated all wells...
Small peat-forming ecosystems in arctic landscapes may play a significant role the regional biogeochemistry of high-latitude systems, yet they are understudied compared to uplands and other major regions North. We present new data set 25 radiocarbon-dated permafrost peat cores sampled around eight low lake sites northern Manitoba (Canada) examine timing initiation controls on accumulation throughout Holocene. used macrofossils charcoal characterize changes plant community fire, we explored...
