Interfacial and Surface Tension
IFT Measurements
Laboratory derived capillary pressure (Pc) data must be converted to reservoir condition values
to be useful in reservoir modeling. Frequently, laboratory results are converted to reservoir values using
estimated or "typical" conversion values for both the laboratory determined and calculated
reservoir values. Reduce uncertainty by reducing the number of assumptions used.
Applications for Tensiometry
- Capillary Pressure (Pc) fluid systems conversion
- Pc to reservoir height conversion
- Determine IFT for use in oilfield calculations
- Screening tool for fluid contamination
- Fluid breakdown determination
Tensiometry using advanced, automated instrumentation removes uncertainty other methods pose as a result of operator
inconsistency. Capabilities: Laboratory IFT values ranging from ambient to elevated temperatures up to 190ºF @
1 atmosphere.
Interfacial Tension (IFT)
- Measured at a liquid/liquid boundary
Surface Tension
- Measurement of the cohesive energy present at any interface
