Monitor the Chemistry of Carbon Capture

There are three basic phases:

  • Pre-Injection
    • This phase begins before the injection well is designed and sets baseline for every component of your system
  • Injection
    • Monitoring the injection fluid over time is imperative.
  • Post-Injection
    • Monitor the capture efficiency. Any leaks? These are often detected in chemical or environmental changes in the near surface.

Consider the Chemistry

  • Residual trapping of CO2 implies that migrating CO2 gets trapped by capillary pressure from water in the pore spaces of the reservoir rock grains.
  • Solubility trapping means to dissolve it into the water (like your favorite soda water) depends upon pressure, temperature and water salinity and, as pH changes (think carbonic acid), so does the solubility.
  • Mineral trapping will result in the precipitation of solid carbonates. These reactions are dependent upon pressure, temperature and composition of the water and the rock.

Stable Isotope Laboratory

  • We provide analytical chemistry that relies on the conservative tracers within the injected CO2, stable isotopes of carbon, oxygen and others.
  • Stable isotopes allow robust interpretation of existing fluids without the introduction of environmentally dangerous (radioactive, poisonous) chemical tracers.
  • Our experience with well integrity and fluid chemistry is unsurpassed.
  • Capture is the keyword. We provide gas and water analyses that provide the ground truth.

Near-Surface Chemistry

Capture is key

  • There are plenty of near-surface chemical reactions that are occurring.
  • Carbon Stable Isotopes of CO2 and Methane (CH4) are critical.
  • Volatile Organic Compound (VOC) intrusion in soil systems must be known.
  • Set a baseline.
