DDG (Drilling Dynamics Geomechanics)
TM
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.
TM
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
TM
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
TM
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
TM
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
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.

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
TM
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.
