SUBSURFACE ANALYSISCHARACTERISE / SERVICE 07
Sample preparation, helium porosity and gas permeability provide a physical baseline for integrated rock and reservoir characterisation.
THE QUESTION
Build a representative sample programme for suitable core or outcrop material. Combine routine measurements with rock texture, mineralogy and pore-system observations to understand variations in reservoir quality.
PREPARE · MEASURE · INTEGRATE
Plug extraction, trimming, cleaning and drying are selected around lithology, condition and test requirements. Core and suitable outcrop material can be assessed; friable, altered or mineral-sensitive samples require an agreed preparation plan.
Helium porosity and gas permeability provide a measured reference for reservoir characterisation. Grain volume, grain density and bulk-volume determination can be included, with the measurement conditions and calculation basis reported.
Relate measured properties to thin-section descriptions, quantitative petrography and HSMQ/FTIR screening. Target XRD or MICP where additional mineral or pore-system detail would help explain the results.
Receive sample-referenced measurements, method information, quality flags and a technical summary. Integrated programmes can include image plates, a findings presentation and a close-out discussion.
Outcrop alteration and sample preparation can affect representativeness. Laboratory results describe the tested material and conditions, not an automatic prediction of subsurface performance.
Connect measurements with petrography ↗CTS is your point of contact for planning the programme and bringing the results together. Where specialist laboratory or interpretation input is required, delivery responsibilities are identified in your proposal.
The scope distinguishes the measurement package and its included outputs from additional processing, interpretation and interactive reporting. Sample requirements and method limitations are confirmed before work begins.
A CONNECTED WORKFLOW
Interpretation boundary
Preparation, weathering, stress and measurement conditions affect comparability. Gas permeability and helium porosity are method-specific measurements; their application to reservoir behaviour requires suitable interpretation.
