    Machine Learning for Geophysical Characterization of Brittleness: Tuscaloosa Marine Shale Case Study.Mark Mlella, Ming Ma, Rui Zhang & Mehdi Mokhtari - 2020 - Interpretation 8 (3):T589-T597.
    Brittleness is one of the most important reservoir properties for unconventional reservoir exploration and production. Better knowledge about the brittleness distribution can help to optimize the hydraulic fracturing operation and lower costs. However, there are very few reliable and effective physical models to predict the spatial distribution of brittleness. We have developed a machine learning-based method to predict subsurface brittleness by using multidiscipline data sets, such as seismic attributes, rock physics, and petrophysics information, which allows us to implement the prediction (...)

    Experimental Evaluation of Ultrasonic Velocities and Anisotropy in the Tuscaloosa Marine Shale Formation.Jamal Ahmadov & Mehdi Mokhtari - forthcoming - Interpretation:1-62.
    Tuscaloosa Marine Shale formation is a clay- and organic-rich emerging shale play with a considerable amount of hydrocarbon resources. Despite the substantial potential, there have been only a few wells drilled and produced in the formation over the recent years. The analyzed TMS samples contain an average of 50 wt% total clay, 27 wt% quartz and 14 wt% calcite and the mineralogy varies considerably over the small intervals. The high amount of clay leads to pronounced anisotropy and the frequent changes (...)

    Intrinsic Anisotropy in Fracture Permeability.Mehdi Mokhtari, Azra N. Tutuncu & Gregory N. Boitnott - 2015 - Interpretation: SEG 3 (3):ST43-ST53.
    Contrary to the assumption in cubic law, the surface of fractures has some degree of roughness, which impacts their fluid dynamics. Incorporating the effect of roughness can improve the simulation of fluid flow in fractures and faults, as well as proppant transport in hydraulic fracturing. To investigate the effect of roughness on the fluid flow, we created a fracture using the Brazilian test, and its roughness was measured using a laser profilometer. Experimental permeability measurements showed a reduction in permeability as (...)

    Characterization of Elastic Mechanical Properties of Tuscaloosa Marine Shale From Well Logs Using the Vti Model.Cristina Mariana Ruse & Mehdi Mokhtari - forthcoming - Interpretation:1-50.
    To avoid steep declines in the Tuscaloosa Marine Shale production, wells are fracture-stimulated to release the hydrocarbons trapped in the matrix of the formation. An accurate estimation of Young’s modulus and Poisson’s ratio is essential for hydraulic fracture propagation. In addition, ignoring the highly heterogeneous and anisotropic character of the Tuscaloosa Marine Shale can lead to erroneous stress values, which subsequently affect hydraulic fracture width estimates and the overall hydraulic fracturing process. An empirical 1D geomechanical model which takes into account (...)
