Our goal is to illuminate the subsurface and mitigate the inherent risks

In TEVERRA, we are taking Geomechanics to a higher level. We believe a new generation of geomechanical characterization, modeling approaches, and tools are needed to maximize value of Geomechanics for oil and gas, geothermal, carbon storage, and subsurface energy storage use cases. Our world-class team provides services and solutions to a full spectrum of geomechanics problems in subsurface applications:

  • 1 to 4-D geomechanical modeling coupled with reservoir, fluid flow, and thermal simulations.

  • Geomechanics without logs (Drilling Dynamics Geomechanics, DDG)

    • Postmortem modeling analysis

    • Working towards real-time modeling

  • Direct in-situ stress measurement (DFISS)

  • Pore pressure prediction and caprock integrity

  • Wellbore stability and casing design

  • Reservoir performance prediction and fault reactivation analysis

  • Optimization for safe hydraulic fracturing and preventing casing deformation

  • Microseismic analysis, prediction, and mitigation

  • Rock mechanics testing design and supervision

Geomechanics is a powerful tool to maximize production of hydrocarbon or heat, minimize risk, and reducing development time and cost. We are proud to save millions of dollars and hundreds of operating days for our clients.

4D Coupled Geomechanical Modeling

TEVERRA develops state-of-the-art field-scale 3D geomechanical modeling to predict and optimize reservoir performance, whether there is a producing reservoir or a CO2 storage formation. Our models are capable of accurately modeling:

  • High temperature high pressure cases

  • Complex faults, fractures, and geologic formations

  • Depletion effect on stress field and rock permeability

  • Faults and fractures reactivation and induced seismicity (prediction and mitigation)

  • Stress and rock property evolution

  • In-fill drilling in complex operational conditions

Our realistic 3D hydraulic fracturing modeling includes the effect of fracture toughness, near-wellbore stress concentration, natural fractures, and the presence of packers. It simulates stress shadowing, different proppant types, pumping schedule, flowback, and production.

Our frac design capability helps clients optimize well spacing and frac design to improve ultimate recovery and prevent frac-hits. This provides a more realistic estimation of induced fracture geometry and the involvement of natural fractures.

Geomechanics without Logs

TEVERRA has developed a disruptive technology, Drilling Dynamics Geomechanics (DDGTM), that enables estimation of geomechanical characteristics including rock mechanical properties, pore pressure, and in-situ stresses from drilling dynamics data only.

Availability of the required logs for geomechanics has always been a major challenge for the geomechanics community and also for the operators to pay the cost of additional logging. These logs are almost never available in the overburden formations and along horizontal wells preventing geomechanical modeling.

This advanced technology, that is based on combined signal processing and physics-informed machine learning, enables constructing geomechanical models from surface to the reservoir and along horizontal wells, thus, creating the opportunity to improve drilling operations, identify and mitigate casing deformation, and optimize completions and stimulation design.

DDG technology has been field tested in several onshore and offshore locations and the Utah FORGE geothermal site.

Subsurface Energy Storage

Earth is the most reliable and long-lasting battery

The subsurface can be heated and used as a medium for thermal energy storage. Synthetic Geothermal Reservoirs (SGR) use the subsurface as a medium for the storage of heat collected in concentrated solar collectors to reliably produce on-demand electrical power using the recovered heat.

Sedimentary systems are well suited for hosting these thermal energy storage systems.

The Concept:

  • Multiple wells drilled into a known high-permeability zone.

  • Solar-heated hot water is injected into the subsurface to be stored and produced later during high electricity demands.

  • Cooled water is recovered from power generation cycle and injected back into a cold reservoir or used for solar-heating.
