Comprehensive Kinetics and Thermodynamic Database for Biogeochemical Reactions

Our geochemical and reactive transport models are equipped with the most comprehensive and accurate kinetic rate laws and equilibrium thermodynamic databases for a wide range of fluid-rock interaction under various temperature, pressure and salinity conditions. 

We provide our clients with deliverables that conform to the EPA Class VI well requirements, ISO 27914 guidelines and align with the special and routine core program testing, including, but not limited to:

  • Model types and background information

  • Input data

  • Assumptions

  • Modeling parameters, kinetics & thermodynamic databases

  • Results - graphical and tabular

  • Reports and/or presentations summarizing the impact of results on long-term CCS performance and model limitations and uncertainties 

We Help Our Clients Acquire
Class VI Well Permits
and Comply with
ISO 27914
For Geologic CO2 Storage

Acquire Class VI Well Permit with the Most Comprehensive Geochemical and Reactive Transport Models per EPA requirements

  • Develop modeling inputs that represent: the mineralogy of the injection formation; the results of formation fluid analyses; pressure, temperature, and pH conditions at depth; and injectate composition.

  • Verify the thermodynamic and kinetic datasets used are suitable to project-specific conditions (e.g. per Section 3.3.1 of the UIC Program Class VI Well Site Characterization Guidance). 

  • Screen potential geochemical reactions such as precipitation and dissolution of minerals that affect storage, confinement, and post-injection site care (PISC) time frame [see 40 CFR 146.93(c)(1)(v)]. 

  • Evaluate compatibility of the carbon dioxide stream with fluids and minerals in the injection and confining zone(s).

  • Wellbore cement degradation analysis as result of CO2 and cement interaction.

  • Predict trace metals e.g. mercury, arsenic, lead, etc. release following dissolution of metal-bearing minerals e.g. iron hydroxides.

Benchmarking Our Models With Novel Laboratory Experiments
 

In collaboration with the Kent State University's Earth Science Department and The University of Texas at Austin's Geoscience Department, we have benchmarked models that can be used for RTM analysis  of complex processes such as changes in porosity-permeability due to minerals precipitation/dissolution during CO2 injection.

We Partner With Major Oilfield Service Companies to Offer Novel Workflows Through Building Digital Twins or Augmenting RCAL (Routine Core Analysis Lab) and SCAL (Special Core Analysis Lab) Experimental Data.

​

​

Fluid and facies (mineralogy and petrology) data, acquired by the core analysis program are used in a multi-tier modeling approach. Example SCAL/RCAL data are:

  • XRD

  • ICP-MS

  • XRF

  • Mercury injection

  • N2 adsorprtion BET surface area

Multiscale RTM 

Given a suitable 3D model of the high-grades facies (image-based or process-based), we have the ability to simulate select core analyses (for augmentation, benchmarking, or sensitivity analysis purposes):

  • Permeability

  • CO2 Entry Pressure

  • CO2/Brine Relative Perm

  • CO2/Brine Capillary Pressure

  • MICP

  • Contact Angle/IFT

  • CO2-Brine-Rock Core Geochemical Stability Tests

  • Core Diffusion and Dispersion Coefficient
