🔬 📚 Another fascinating research paper that investigates the relationship between stratigraphy, stress, and microseismicity at the Hydraulic Fracture Test Site-1 in the Midland Basin 🌐 📄 This paper titled: “Stratigraphically Controlled Stress Variations at the Hydraulic Fracture Test Site-1 in the Midland Basin, TX” by Arjun Kohli and Mark Zoback from the Stanford University focuses on the Hydraulic Fracture Test Site-1, which comprises two sets of horizontal wells in the Wolfcamp shale and a deviated well drilled after hydraulic fracturing. The research investigates the variations in stress and their stratigraphic controls. 💡 This study represents a general approach for integrating stress measurements and rock properties to predict hydraulic fracture growth and the characteristics of injection-induced microseismicity. It’s a valuable resource for anyone interested in geomechanics, unconventional reservoirs, and hydraulic fracturing. Dive in, learn, and share your thoughts! 🔍 here are some key Insights: 1. Stratigraphy and Stress: • The minimum principal stress varies with depth, with high values in strata with high clay and organic content. • This is consistent with the theory of viscous stress relaxation. 2. Hydraulic Fracture Growth: • Data from core, logs, and hydraulic fracturing stages were integrated to construct a stress profile for the Wolfcamp sequence. • This profile predicts the pressure required for hydraulic fracture growth. 3. Pre-existing Faults: • The results were applied to fracture orientation data to determine the population of pre-existing faults expected to slip during stimulation. 4. Microseismic Focal Plane Mechanisms: • Microseismic focal plane mechanisms were determined, revealing slip on steeply dipping planes striking NW. • This is consistent with the orientations of potentially active faults predicted by the stress model.

I am pleased to share that our most recent research paper has been published in the Journal of Rock Mechanics and Geotechnical Engineering. I would like to express my sincere appreciation to my supervisors, Prof. Ali Saeidi and Dr. Shahriyar Heidarzadeh, Ph.D., P.Eng. for their excellent support and help. In this article, we thoroughly determined the uncertainties of geomechanical parameters of metamorphic, emphasizing the significance of data treatment process, schistosity angle and the mineral composition.

#SoilScience_Quotations Soil replacement stands as a widely recognized method for enhancing shear strength, augmenting bearing capacity, and mitigating consolidation settlement under shallow foundations. The complete replacement of weak soils is impractical due to the associated high costs, thus necessitating the consideration of partial replacement as a viable alternative, particularly in light of cost considerations. Nonetheless, there exists a dearth of research exploring the various factors that significantly influence the determination of the thickness of the replacement layer. Typically, the optimal thickness of the replacement layer is deduced from experience, which may lead to unnecessary expenditures. Numerous studies have examined the soil replacement technique, with the majority focusing on the augmentation of soil bearing capacity and/or the reduction of expected soil settlement. Conversely, there is a scarcity of research that takes into account the cost of foundation works as a critical factor in determining the thickness of the replacement layer. The cost of foundation works is an essential consideration, alongside the enhancement of soil bearing capacity and the reduction of settlement. This is a good study on the subject, aiming to be useful. #geotechnicalengineering #earthworks #engineering #soilmechanics #soilstabilization #soiltesting #geomembrane #geosynthetics #geophysical

I officially present to you my bread and butter of storm inlet calculations, the Rational Rational Method (Dynamo Version). This workflow has taken WEEKS off of my storm design and I hope it does the same for you. The video may be a little long but I promise it is worth it. The four steps to optimize your rational process are: 1. Define Impervious Cover for your site 2. Calculate the time of concentration for each basin 3. Calculate 'c' values and flows by intersecting basins with your defined impervious cover 4. Export to hydraflow storm sewers to size your pipes Now available at https://lnkd.in/gse2Hpry #DynamoBIM #Civil3D #Hydrology #StormDesign #Autodesk Retrieve Technologies, Inc.
