GviscTM
Viscosity estimations when conventional analysis methods fail!
Conventional viscosity and API gravity of oil or bitumen from core samples that do not yield oil by mechanical extraction cannot be measured. At Gushor, we are still able to accurately estimate dead oil bitumen viscosity using our proprietary method, GViscâ?¢. GViscTM; provides a bitumen viscosity by using a specially tailored solvent cocktail that preserves accurate measurement of oil viscosity with little light end losses and a means to separate the impact of the solvent on the oil phase viscosity. GViscTM; can be done when conventional mechanical bitumen recovery from unaltered and fresh reservoir samples fails. Often this occurs when bitumen saturation or reservoir permeability is low combined with high bitumen viscosity or when samples are too small for centrifugation. Most commonly, we see this in carbonate-hosted bitumen core samples.
GViscTM; can:
- Accurately estimate dead oil bitumen viscosity by solvent-extracting conventional core, and
- Be applied to carbonate, low saturation, low porosity, small, or superviscous oil core samples.
GViscTM; Benefits:
- Alternative to conventional viscosity measurements for difficult or fresh samples.
- Produce an equivalent viscosity to one derived by centrifuge extraction and viscometry.
- Designed for carbonate-bearing bitumen samples.
- Allows for resource assessment for superviscous reservoirs.
- Good viscosity profiling to aid well placement and recovery strategy design, and
- Viscosity estimations when conventional analysis methods fail.
