• Developing and deploying breakthrough technology for mapping hydraulic fractures from surface pressure monitoring data in offset wells using Geomechanics fundamentals and data analysis.
• I delivered 2 projects with mapped fracture geometries to clients to improve completion design.
• The idea I generated, when implemented, reduced computation cost of IMAGE Frac® over 100 times.

• I lead geomechanics support of Unconventional assets (Permian, Eagle Ford) providing optimal horizontal well landing depth and completion recommendations.
• I identified cost-effective 30% production uplift by optimizing completions economics using 3D hydraulic fracture modeling (Dynardo, optiSLang).
• I reduced uncertainties in the input geomechanical parameters for the models by designing and executing geomechanical core testing programs and integrating lab test data with continuous material profiles derived from.
• I was recognized as an expert giving training on Multivariate Analysis and Geomechanics for Unconventionals.

• I conducted research for thermal in-situ upgrading/conversion processes in extra-heavy oil and oil shale reservoirs.
• I ensured the safety of thermal operations by constructing reservoir-scale models (Abaqus) for geomechanical risk assessment (surface heave and subsidence, reservoir compaction, seal integrity, and well integrity).
• I decreased uncertainties in input parameters for geomechanical models, analyzing 550 high-temperature triaxial tests, building constitutive models, and up-scaling to rock mass; developed MATLAB scripts.
• I delivered 3 proprietary ABAQUS plug-ins, leading development by Simulia, exceeding expectations.

London, England, GB

Developed an innovative numerical method for constructing a 3D initial in-situ stress field that satisfies equilibrium conditions and optimizes the match to available field measurements for complex geometries. The iterative optimization procedure with regularization was implemented in Matlab coupled with a 3D finite element model in Comsol Multiphysics..
