Oilfield Geomechanics Llc

What Oilfield Geomechanics Llc does

OilField Geomechanics LLC (OFG) is a woman-owned boutique geomechanics consulting firm founded in April 2014 by Dr. Marisela Sanchez-Nagel (President) and Dr. Neal Nagel (Chief Engineer and Principal). The firm operates exclusively through its two co-founders from a home office in Richmond, Texas, delivering engineering consulting, professional training, and litigation expert witness support for oil & gas operators (conventional and unconventional), solution mining operators, underground storage developers, and legal counsel. Project reach spans the United States, Canada, Norway, and Latin America including Colombia, Venezuela, and Argentina.

OFG's core technical work centers on geomechanical modeling — building 1D and 3D Mechanical Earth Models populated from well logs, seismic, lab testing, and drilling event data — and applying analytical, empirical, and numerical methods (notably FLAC3D) to predict rock mass behavior under varying stress, pressure, and thermal conditions. The service portfolio covers wellbore stability and safe mudweight window determination, hydraulic fracturing optimization (including stress shadow analysis, fracture-driven interactions, and casing deformation evaluation), caprock integrity for CCS and underground storage, fault stability and induced/triggered seismicity assessment, solution mining cavern design and stability modeling, sand production prediction, pore pressure prediction, and naturally fractured reservoir characterization including DFN-coupled geomechanics. A distinguishing technical position is OFG's emphasis on rock fabric characterization in unconventional plays, challenging the conventional assumption of rock homogeneity in hydraulic fracture modeling.

OFG monetizes through three professional services revenue streams: project-based consulting engagements (as independent advisor, project team member, or turn-key delivery), training courses (eight discrete programs offered in-person in Houston and online, distributed both directly and through channel partners RPS Nautilus, Geologica, SPE, and ARMA), and litigation expert witness support on a case-by-case basis. Pricing is quote-based for consulting and litigation work and per-attendee for open-enrollment training. The firm reaches clients through SPE and ARMA conference presentations, an extensive free white paper library, adjunct professorship roles at the University of North Dakota, and direct professional networking by the founders. No external funding, institutional investors, or growth equity is involved, and the firm has remained at a 2-person headcount since founding.

Core offering

OilField Geomechanics LLC (OFG) is a boutique consulting firm that provides geomechanics engineering services for oil & gas operators, solution mining companies, and underground storage projects. The firm delivers consulting engagements, professional training courses, and litigation/expert witness support, specializing in 1D and 3D geomechanical modeling, hydraulic fracturing optimization, wellbore stability, cap rock integrity, and fault stability analysis.

Product overview

OilField Geomechanics LLC is a woman-owned consulting and training firm offering geomechanics engineering services. The company provides a portfolio of consulting services organized into three main areas: Geomechanics Fundamentals (1D and 3D geomechanical models, laboratory testing), Oil and Gas Geomechanics (wellbore stability, hydraulic fracturing, cap rock integrity, induced seismicity), and Solution Mining & Underground Storage Geomechanics (cavern design and modeling, CCS evaluations). The company also offers professional training courses across eight distinct programs covering geomechanics fundamentals through specialized topics like unconventionals and energy transition applications. Additionally, the firm provides litigation and expert witness support services for geomechanics-related disputes. The offerings function as independent consulting services rather than a unified software platform.
