SUBSURFACE ANALYSISCHARACTERISE / SERVICE 08
Wettability assessment, fluid compatibility and formation-damage investigations connect rock characterisation with the fluids and conditions that matter to your project.
THE QUESTION
The same rock can behave differently as fluid composition, saturation history and test conditions change. Define the intended fluid exposure and select representative samples before designing the programme.
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.
SURFACE · COMPATIBILITY · FLOW
Understand surface preference, check fluid compatibility and investigate changes in flow performance. Select one workstream or connect all three around the same rock and fluid system.
Assess wetting behaviour with the selected fluid system, preparation history and test method. Use the findings to inform displacement interpretation and further SCAL work.
Connect with SCAL interpretation ↗Investigate the planned fluids and their interaction with the rock. Agree the mixing or exposure conditions and the observations needed to assess compatibility.
Add mineralogical context ↗Compare baseline and post-exposure performance using an agreed test sequence. Assess permeability response and use complementary observations to investigate potential impairment mechanisms.
Establish the physical baseline ↗Conceptual illustrations · not to scale.
BEFORE · EXPOSURE · AFTER
Record sample condition, preparation and initial properties. Select complementary mineralogy or CT where it will help explain the response.
Apply the agreed fluid sequence and exposure or flow conditions, retaining a clear record of composition, temperature and pressure.
Compare the relevant measurements and observations. Separate measured changes from proposed mechanisms and identify further tests where needed.
A CONNECTED WORKFLOW
Interpretation boundary
Results apply to the samples, fluids and conditions tested. Preparation and saturation history affect interpretation; laboratory findings need geological and engineering context before field application.
