Subsurface Assessments for Carbon Capture, Utilization, and Storage Via Rock Volatiles Stratigraphy
Derisking before spending money can be done using legacy offset drilling materials.
Using existing geological materials to derisk potential CCUS/CCS sites prior to drilling and investment of capital with a detailed assessment of the subsurface system via analysis of volatiles.
For our CCUS/CCS subsurface assessments, Rock Volatiles Stratigraphy (RVS) is used. RVS assesses if evidence of past events and/or features in the subsurface that indicate CO2 has previously escaped or has a significant opportunity to:
- Past CO2 Migration
- Loss Of Reservoir Pressure
- Communication Through adjacent boreholes
- Communication Via meteoritic water
What is RVS?
RVS is a non-intrusive technique uses a novel cyro-trap mass spectrometry system developed by AHS to gently extract, identify, and quantify volatiles in geological materials.
Functions regardless of age of sample or mud system
1-1.5 g of rock sample is subjected to a gentle vacuum extraction at room temperature.
All compounds are measured at two different vacuum extraction conditions providing information on permeability and grain surface interactions.
Mechanical strength of the rock is also measured by uniaxial crushing.
Over 120 different direct measurements per sample provide a detailed description of the subsurface geochemistry.
De-risk capital and increase confidence in your drilling with CCUS/CCS subsurface assessments via RVS. Learn more by checking out our past case studies and published works.
