TECHNOLOGIES:

DDG     (Drilling Dynamics Geomechanics)

We developed DDG    to maximize ultimate recovery and minimize risks of wellbore integrity, casing deformation, induced seismicity, and environmental hazards. To ensure safe and cost-effective drilling and hydraulic fracturing operations, knowledge of the subsurface geomechanical characteristics is essential. The currently available methodologies for geomechanical modeling are heavily dependent on well logs which are not always available at the quantity and quality required for geomechanics.

The Drillbit is the first logging tool to touch the rock formation generating a large volume of rich dataset. Using robust interpretation schemes, these data can be used to evaluate the geomechanical characteristics of the formations. TEVERRA’s Drilling Dynamics Geomechanics (DDG) technology solves this problem. Its architecture processes complex drilling dynamics data and extracts valuable geomechanical characteristics It enables high-resolution geomechanical modeling and wellbore stability analysis for entire well length without requiring any logs. DDG has been successfully tested in several onshore and offshore locations around the world.

CompressDeck

Over the past two decades, there have been significant advances in sensing technologies and data acquisition systems. These datasets require swift, automated, and affordable interpretation and storage to enable both real-time decision-making and post-analysis. However, conventional data analysis and interpretation mechanisms are often rudimentary, requiring significant time to transmit high-resolution data to the cloud, and the processing needs substantial human intervention.

Monitoring, Verification, and Accounting (MVA) to confirm the permanent storage of CO2 in geological formations is a significant cost component of any carbon storage campaign and is indeed necessary for its success. Automated and low-cost MVA solutions can advance Carbon Capture and Storage (CCS) towards commercialization by providing a reliable and real-time control option over the reservoir while reducing associated costs. These solutions should address the data management bottlenecks present today, including insufficient bandwidth, inadequate storage, and limited connectivity. A key solution to overcome these challenges is to reduce the volume of the recorded data streamed on-site with CompressDeck.​

FluidTrack

FluidTrack™ is a newly developed technology that can monitor the spatial distribution of injected CO2 in near real-time using geophysical field measurement data. It provides critical information for agile decision-making to mitigate risks such as CO2 leakage and fault reactivation, as well as to improve storage utilization efficiency. This is achieved by integrating rock physics modeling and advanced machine learning algorithms. The workflow built within FluidTrack has broad applicability for subsurface monitoring of pore fluid evolution associated with physical relationships and rock properties.

For example, in the context of CCS (Carbon Capture and Storage) and plume migration, we predict that our workflow will track the evolution of the CO2 plume, and help with timely identification and risk mitigation of CO2 leakage and induced seismicity.

GeoDeck

OurGeoDeck™ software  eliminates or minimizes the rigorous setup, the time and cost, and the complexity faced when visualizing geologic subsurface data . GeoDeck makes the visualization process more productive, scalable, and accessible to a wider range of audiences. The software is designed and customized for people who do not necessarily have the time or skill to use conventional software. It extracts insights from physics-based analytical workflows which are notoriously time-consuming and complicated. To offer maximum simplicity and accessibility, GeoDeck uses the web, i.e., it is available as a regular website that users can load in their browsers.

The Application Programming Interface (API) exposed in browser environments is employed to create a fast and seamless user experience on the web with modern graphics. Moreover, since subsurface data are often too large to be handled by browsers (or even users’ machines), GeoDeck intelligently and dynamically loads the current data to be viewed. We believe that style and simplicity matter. GeoDeck lets users seamlessly perform uncertainty studies on static and dynamic subsurface properties under different operational or computational scenarios through its smart sampling mechanism. Users are usually one click away from generating the needed graphs, such as heat maps, iso-surfaces, scatterplots, statistics, etc., for presentations and reports.

​Finally, GeoDeck has a long-term vision for data visualization through ever-increasing virtual reality (VR) and augmented reality (AR) technologies such as Oculus, Google VR, and other popular AR/VR headsets. At TEVERRA, we believe the ultimate immersive experience is only possible through VR and AR, and our software is designed to accommodate future extended reality (XR) integration on the web.

ConvertDeck 

ConvertDeck analyzes geothermal production for both electricity and direct-use (heating/cooling) opportunities, while also assessing local market utilization potential. The tool serves dual purposes: it identifies wells that meet predefined financial criteria based on input data, and it evaluates potential use case scenarios to estimate their economic value. This integration of expert analysis across multiple disciplines into a single intuitive platform significantly reduces evaluation time, leading to faster and more cost-effective analyses.

ConvertDeck Benefits:

• Reduces the hydrocarbon-to-geothermal well conversion evaluation study time 

• Increases well conversion profitability by increasing the understanding of the opportunity 

• Contains over 100 unique parameters to calculate an accurate estimate of the geothermal economic potential

• De-risks conversion project by identifying the most profitable projects

• Designed for quick repeat screening to analyze multiple end use scenarios

• Prevents overly conservative valuations

ResStor

Our groundbreaking ResStor    technology uses subsurface rocks to store heat or cold energy. ResStor captures heat from waste sources or excess power from renewables, storing it in geological formations as thermal energy for over 1,000 hours with high efficiency. This enables reliable direct heating/cooling or on-demand electricity production using the recovered heat.

MMARCT   

The evolution of fractures in reservoirs determines the efficacy of an enhanced geothermal system (EGS). Monitoring changes in fracture network characteristics aids in the assessment of reservoir performance. Real-time EGS assessments provide valuable information to optimize stimulation schemes and maximize heat production. Our AI-based system would characterize differences in various aspects of geology/reservoir, regulation/permitting, and available data between old and new fields. The value of this project includes:

• Monitoring the evolution of fractures under different operational conditions

• Assessing, improving, and predicting EGS performance from prior learning

• Developing a site-specific EGS design from knowledge of natural fractures in heat production

DFISS

TEVERRA is developing an innovative downhole system for the direct measurement of in-situ stresses. This system will have a significant impact on improving the accuracy and validity of the designs and models used for subsurface operations, including drilling, completions, stimulation, injection, and reservoir management. The lack of sufficiently reliable knowledge of in-situ stresses costs the energy industry billions of dollars every year. These losses are associated with non-productive time during drilling caused by stress-related problems, poor well design including trajectory, casing, and mud designs, failure of hydraulic fracturing treatments due to incorrect estimation of the pressure required to break down zones, erroneous prediction of fracture dimensions/direction, poor evaluation of the shear strength/conductivity of natural fractures, flawed placement of parent and child wells, well integrity issues, and lack of understanding of the risks during production.

EXPERTISE

• Targeted resource characterization and planning
• Developing technology to de-risk subsurface development projects
• Original collaborative research to solve the energy industry's greatest challenges

GEOTHERMAL ENERGY

We believe geothermal is part of the foundation for a sustainable clean energy future.

• De-risking exploration
• Prolonging asset life and resource production
• Optimizing asset profitability and revenue generation
• Developing innovative power systems
• Opening new markets and novel subsurface use cases

TEVERRA offers a holistic geothermal energy characterization and utilization resource, from greenfield exploration and geothermal system conceptual and numerical modeling, through to reserves calculation and power system design.

TEVERRA has experience in each development phase across:

Volcanic, Extensional, Sedimentary basin geothermal exploration, and Low, medium, and high temperature resources worldwide.

TEVERRA has experience collating diverse datasets to perform geothermal play fairway analysis as the first step in an exploration and development plan. Extensive experience with global datasets at the regional and development field scale gives TEVERRA the unique capabilities to recognize geologic differences and adapt processing workflows during these early stages of exploration.

Geothermal Resource Exploration and Well Planning

​Geothermal play fairway analysis identifies high priority geothermal exploration targets, which TEVERRA uses to develop a detailed exploration plan with data collection campaigns, geothermal market analysis, and thermal gradient exploration drilling. Detailed data collection culminates in a field scale geothermal system conceptual model that leads to the development of a preliminary numerical model and production well targeting.

Geothermal Reserves Calculation and Power System Design

Once a project is at the production well drilling stage, the TEVERRA team provides well placement and well design, and after drilling, production test analysis and refinement of the geothermal system numerical and conceptual model. At this stage, final reserves calculations are made utilizing production test data and the geothermal system development goes to the power systems design phase.

Enhanced Geothermal System (EGS) development capabilities

Maximizing heat production, optimizing EGS development design, and predicting reservoir performance are solutions we offer for EGS development.

TEVERRA is the industry leader in developing field-scale 4D Coupled Hydro-thermo-mechanical models for geothermal projects to optimize EGS design, predict reservoir performance, and maximize heat production. These models accurately couple subsurface in-situ stresses and rock properties with temperature and fluid flow regimes in complex geometries by utilizing high performance computing and reduced-order modeling.

Oil and gas wells to geothermal conversion capabilities

TEVERRA has developed a well screening tool specifically for selecting the appropriate petroleum wells to convert to geothermal electricity or heat. ConvertDeck  takes input data associated with well design, reservoir properties, historical production, existing infrastructure, financial metrics, and more, and quantifies the potential power production and calculates cost and economic value of the geothermal resource.

ConvertDeck analyzes the geothermal production for both electricity and direct-use (heating/cooling) opportunities while also examining the local utilization market potential. The tool can be used in two ways. It can identify wells that will achieve pre-determined financial requirements given the input data, or it can identify potential use case scenarios and then estimate the economic value of the different scenarios. This decreases evaluation time by combining expert analysis from multiple disciplines into one intuitive platform. Decreasing evaluation time produces faster and more cost-effective analysis.

ConvertDeck™ Benefits:

​​​Reduces the hydrocarbon-to-geothermal well conversion evaluation study time

Increases well conversion profitability by increasing the understanding of the opportunity

Contains over 100 unique parameters to calculate an accurate estimate of the geothermal economic potential

De-risks conversion project by identifying the most profitable projects

Designed for quick repeat screening to analyze multiple end use scenarios

Prevents overly conservative valuations

Offshore geothermal capabilities

We are on the cutting edge of research as the geothermal market continues to expand.

Offshore hydrocarbons are the lowest carbon intensity hydrocarbons produced worldwide. As such, continued offshore production should continue as part of a net-zero energy company strategy and further opportunities to decarbonize offshore hydrocarbon production should be continually examined. One such opportunity is offshore geothermal energy production that can be co-located with existing hydrocarbon production. Offshore platforms can be assets that provide petroleum companies an opportunity to decrease the cost of decarbonization efforts by using this existing infrastructure for geothermal energy production. Drilling geothermal wells from existing platforms re-utilizes the existing platform and then could optimize wells to be more productive. TEVERRA has experience performing offshore resource assessments and designing innovative powerplant systems that optimize power production offshore. We have performed such assessments in the Gulf of Mexico, the North Sea, West Africa, and the MENA region.

Power Systems Advisement

TEVERRA partners with leading geothermal experts to design fit-for-purpose power systems from modular, kW scale power generation up to MW power plant design. We have experience designing both electrical power production and direct-use heat utilization systems. In a power systems advisory role, we analyze all potential power systems and use cases, meaning we are conversion technology agnostic and can provide the best system for the associated geothermal resource. Our team includes creative thinkers that provide unique solutions that optimize power utilization and minimize utilization cost.

Geothermal Mentorship and Training

Knowledge transfer is a core tenant to our business mission and training workshops were the original product offerings of TEVERRA. TEVERRA shares geothermal expertise through training and mentorship, offered as individual classes or as a component of larger projects. Knowledge transfer is a suggested component with our geothermal projects to enhance competency for oil companies. Through this, we aim to equip our clients for future geothermal exploration and production.

Geothermal exploration is similar to hydrocarbon exploration in many ways; although there are important and significant differences that have to be learned. The TEVERRA geothermal team has developed 1-day to 5-day short courses on geothermal basics, geothermal exploration, and power systems design. These courses have been taught to all experience levels including industry professionals, government personnel, students, and educators. These courses were developed and based on decades of academic research, industry experience, and teaching expertise.

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.

CARBON STORAGE

Net-zero carbon is not a dream

Our solutions evaluate viability of permanent CO2 storage by understanding the direct correlation with the reservoir integrity and how it evolves in addition to identifying and mitigating possible risks.

Converting Earth to a safe and permanent storage for CO2

Enabling real-time monitoring and visualization of CO2 plume is our focus

Our advanced signal processing and artificial intelligent capabilities enable smart and timely decision making which is the  key in safe CO2 sequestration process

We are developing an award-winning and intuitive platform for subsurface visualization

The key to the effective injection of CO2 into the subsurface formations, including depleted oil and gas reservoirs for EOR, is a detailed characterization of the formation properties, in-situ stresses, natural fractures network, seal capacity of cap rock, and formation pressure. This is our expertise at TEVERRA.

Monitoring, Verification, and Accounting (MVA) to confirm permanent storage of CO2 in geological formations is a significant cost component of any carbon storage campaign and necessary for its success. TEVERRA is researching automated and low-cost MVA solutions to advance carbon storage toward commercialization by providing a reliable and real-time control option over the reservoir and reducing the associated costs.

Successful storage of CO2 in geological formations relies on accurate knowledge of the subsurface state of stress and its evolution during and after injection to guarantee safe and permanent storage of CO2. Cost effective but accurate estimation of in-situ stresses independent from scarcely available logs is a true gamechanger for geomechanical modeling for not only carbon storage but also oil and gas and geothermal applications.

OIL & GAS

Focusing on lowering the carbon impact for traditional hydrocarbons: Unlocking locked reserves: Drilling un-drillables, and predicting un-predictables, Saving millions of dollars for your assets

Drilling and production from deepwater and HPHT fields are among the most challenging operations in the conventional oil and gas industry. Due to significantly higher pressure and temperature, as well as a narrow mud weight window, safe drilling, completion, and production from these resources require advanced knowledge of the subsurface and cutting-edge technologies. TEVERRA’s personnel have extensive experience in modeling and designing deepwater and HPHT operations in the Gulf of Mexico, North Sea, offshore Africa, Pakistan, and the Caspian Sea.

We believe production from unconventional resources requires unconventional thinking

At TEVERRA, we pay special attention to the optimized development of unconventional resources.

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.
