(2017-10-09)Shape memory alloys (SMAs) are promising candidates for solid state actuators since they have the highest energy density among all active materials. However, before SMA solid state actuators can be used in practical ...
-
(2023-08-08)This research study aimed to develop and execute a systematic experimental protocol for testing different variations of 2D honeycomb and diamond sandwich architected structures. Each sandwich structure was tested under ...
-
(2010-01-16)Quantifying the influence of pressure on the effective elastic rock properties is important for applications in rock physics and reservoir characterization. Here I investigate the relationship between effective pressure ...
-
(2012-10-30)The classical theory of linear elastic fracture mechanics for a quasi-static crack in an infinite linear elastic body has two significant mathematical inconsistencies: it predicts unbounded crack-tip stresses and an ...
-
Based on the asymptotic approximation of the diffusivity equation for slightly compressible fluids, our research team looked into its application in early time fracture interference effects and late time reservoir shape ...

The Effect of Proppant Size and Concentration on Hydraulic Fracture Conductivity in Shale Reservoirs (2013-04-11)Hydraulic fracture conductivity in ultra-low permeability shale reservoirs is directly related to well productivity. The main goal of hydraulic fracturing in shale formations is to create a network of conductive pathways ...
-
(Texas A&M University, 2006-08-16)Acid fracturing is one of the preferred methods to stimulate wells in carbonate reservoirs. It consists of injecting an acid solution at high enough pressure to break down the formation and to propagate a two-wing crack ...
-
(Texas A&M University, 2005-11-01)To characterize low-pressure, brittle deformation in porous, granular rock, notchcut cylinders (30 mm neck diameter) of Berea Sandstone were extended in a triaxial apparatus from 10 to 160 MPa confining pressure at strain ...
-
(2014-12-16)The recently proposed Interferometric Neighboring Fracture (INF) localization method places unique and demanding constraints on relative travel time measurement accuracy and precision, while sampling a function of relative ...
-
(2009-05-15)Determining fracture characteristics at the laboratory scale is a major challenge. It is known that fracture characteristics are scale dependent; as such, the minimum sample size should be deduced in order to scale to ...
-
(2014-10-29)The reservoir permeability is an essential input for the optimum design of modern hydraulic fracture treatments, which are undeniably the crucial technology involved in the development of tight and/or unconventional gas ...
-
(2017-08-01)In order to gain a more fundamental understanding of multifunctional epoxy nanocomposites, model systems containing surface functionalized multi walled carbon nanotubes (MWCNTs) and thermoplastic microparticles were ...
-
(2013-08-19)In order to understand the complex fracture network that controls water movement in Sherrod Area of Spraberry Field in West Texas and to better manage the on-going waterflood performance, a field scale inter-well tracer ...
-
(2012-02-14)The recent changes in the Texas Department of Transportation (TxDOT) hot mix asphalt (HMA) mix design procedures to ensure that the mixture types routinely used on Texas highways are not prone to rutting raised concerns ...
-
(2011-02-22)This work of well performance modeling is focused on solving problems of transient and pseudo-steady state fluid flow in a rectilinear closed boundaries reservoir. This model has been applied to predict and to optimize gas ...
-
(Texas A&M University, 2004-09-30)This research presents an approach to accurately simulate flow experiments through a fractured core using experimental, stochastic, and simulation techniques. Very often, a fracture is assumed as a set of smooth parallel ...
-
(2018-12-04)Known as one of the most productive shale gas plays in the US, the Haynesville shale gas play covers 9,000 square miles from East Texas to North Louisiana. With horizontal wells and multi-stage hydraulic fracturing, gas ...
-
(2016-12-15)A major challenge that is currently facing the mechanics of materials community is the accurate prediction of fracture in advanced ductile materials. The intertwined effects of intrinsic and extrinsic factors make ductile ...
