Fracture characterization from seismic measurements in a borehole
Fracture characterization is important for optimal recovery of hydrocarbons. In this thesis, we develop techniques to characterize natural and hydraulic fractures using seismic measurements in a borehole. We first develop methods to characterize a fracture intersecting an open borehole by studying …

Fracture characterization of thin bonded asphalt concrete overlay systems
… benefits. Conventional asphalt concrete fracture tests were developed for pavements with homogeneous asphalt concrete mixtures, and typically their thicknesses exceed two inches. The use of spray paver technology for construction of TBO leads to continuously varying asphalt binder …

Mode I Delamination Fracture Characterization of Polymeric Composites under Elevated Temperature
… methodologies that are based on linear elastic fracture mechanics are inadequate to characterize delamination fracture properties under elevated temperature when PMC properties become time-, loading-history, and rate-dependent. A new experimental methodology based on linear viscoelastic fracture …

Fracture characterization of cortical bone at the micrometer and nanometer length scales
Fracture in bone is common in a wide variety of health situations, and is of particular interest to structural engineers due to the adaptability of bone tissue in response to applied stresses. Investigations into the fracture processes within bone tissue can aid in developing medical therapies to …

Fracture characterization of clays and clay-like materials using flattened Brazilian Test
Fracture mechanics has been used for many years to study the mechanical behavior of brittle and quasi-brittle materials like concrete, rock, wood, and ceramics. To date, the application of fracture mechanics to soils has been limited to dry and partially saturated soils where soil consistency …

Interpretation and Fracture Characterization of Early-Cretaceous Buda Limestone Formation Using Post-Stack 3D Seismic Data in Zavala County, Texas
<p>The Buda Limestone is a naturally fractured Early Cretaceous carbonate formation in south Texas which unconformably underlies the Eagle Ford Shale. Matrix porosity of the Buda is less than 6%, therefore natural fractures improve the potential for commercial hydrocarbon production from this tight …

Time-lapse seismic AVAz in the Stocker Field
… to be economically productive. Zones of high fracture density are desired due to the increase in permeability they would have. Thus, fracture characterization is an essential part of production planning in unconventional reservoirs. Amplitude Variation with Offset and Azimuth (AVAz) …

Facies architecture and mechanical stratigraphy of Mississippian grainy and muddy carbonate sediment gravity-flow deposits: Rancheria Formation, Sacramento Mountains, New Mexico
… of depositional processes, facies architecture, fracture distribution, and the resultant mechanical stratigraphy. Outcrops of the Rancheria Formation in the Sacramento Mountains, New Mexico represent a Mississippian carbonate slope system that is spectacularly exposed for sedimentologic and …

A design protocol for failure resilient architected metamaterials
… assumed that a material property known as fracture toughness exists for these materials akin to usual continuum solids, without a-posteriori experimental validation. In fact, all existing experimental measurements are based on metamaterial specimens comprising only dozens to at most a few …

EOS modeling and reservoir simulation study of Bakken gas injection improved oil recovery in the Elm Coulee field, Montana
… effect on the simulation results. Long hydraulic fractures shortened CO2 break-through time greatly and increased CO2 production. Water-alternating-gas injection schemes and injection-alternating-shut-in schemes can provide more options for gas injection EOR projects, especially for gas production …

Ductile fracture at intermediate stress triaxialities : experimental investigations and micro-mechanical modeling
Accurate predictions of the onset of ductile fracture play an increasingly important role in the design of lightweight sheet metal structures. With the development of virtual prototyping practices, most transportation vehicles are now computer-engineered in great detail before launching their mass …

Dynamic Mixed-Mode Fracture of Bonded Composite Joints for Automotive Crashworthiness
An experimental evaluation of the mixed-mode fracture behavior of bonded composite joints is presented. Commonly used experimental techniques for characterizing the mode I, mixed-mode I/II, mode II, and mode III fracture behavior have been employed for the purpose of developing a fracture envelope …

Enhanced completion evaluations in unconventional reservoirs: new applications of fiber optic sensing and machine learning
… compare the hydraulic connectivity of induced fractures near the wellbore on a stage-by-stage basis. We also discuss a new machine learning multivariate analysis workflow designed to identify the most correlated variables within complex, high-dimensional datasets. After validating the …
