Utilizing Rock Volatiles Stratigraphy For Petroleum System Analysis
AHS provides unique insights into the petroleum system in oil and gas exploration/appraisal wells by directly measuring the hydrocarbons (HCs) present in the rock sample using AHS’s Rock Volatiles Stratigraphy (RVS) technique/technology. Inform your exploration and appraisal decisions by directly measuring the HCs and water present in the rock samples, including unpreserved PDC bit cuttings, from the well – ideal in cases where a new play is being developed, low resistivity pay is difficult to identify, carbonate systems where traditional analysis approaches are highly challenged, or after the fact post-mortems to understand anomalous results and if a petroleum system is even present in the case of dry holes.
Typical Oil and Gas Exploration RVS Usage
- Pay Zone Identification
- Resource Characterization
- Reservoir Characterization
- Proximity to Pay Indicators – vertical and lateral
- Petroleum System Assessment
- Identifying Migration Pathways
- Acreage Utilization/High Grading
- Postmortems
- Identifying By-Passed Pay
- Operational Decisions – testing zones, landing, perforations, lateral completions
- Evaluating Seals/Faults/Chemical Compartments
Rock Volatiles Stratigraphy offered a unique opportunity to acquire these insights using legacy materials without deploying downhole tools or collecting fresh materials – understand the subsurface of a prospect before you drill.
What is RSV?
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.
