ProxViscTM
Estimate viscosity from old or public core!
ProxViscTM; utilizes molecular geochemistry to predict bitumen viscosity and/or API gravity from analysis of hydrocarbon concentrations. The method is especially useful to estimate viscosity of samples from which bitumen cannot be recovered or do not produce representative in-reservoir oil. For most accurate viscosity estimation, a data set of chemical measurements and physical property data for a suite of calibration oils related to the test samples provide an appropriate relationship between viscosity and chemical composition.
ProxViscTM; effectively estimates viscosity for samples that yield no mechanically extracted oil:
- Small, low porosity, or low oil saturation samples.
- Highly viscous oil, outcrop samples, or cuttings.
- Drilling mud contaminated samples.
- Old core stored at room or frozen temperatures i.e. volatiles have been lost during storage, and
- Cuttings which do not yield adequate oil.
ProxViscTM; Benefits
- Land sales oil quality surveys from public core.
- Viscosity from low oil yield cuttings.
- Profiling in carbonates and other low oil saturation rocks, and
- Partially-contaminated cutting samples.
