In addition to fluid property analysis, chemical analysis, and engineering, Gushor Inc. also develops geosolution software.
GNAWDTM
GNAWDTM is a pre-drill predictor of oil composition and fluid properties to assess levels of biodegradation. Biodegradation of crude oil in subsurface petroleum reservoirs has adversely impacted the majority of the world's oil inventory by making recovery and refining more costly.
GNAWDTM, a compositional petroleum charge and degradation model, simulates biodegradation via removal of biodegradable hydrocarbons at temperature-dependant flux rate and fresh oil charge into a reservoir over geological time. This fluid property prediction tool integrates oil charge history and thermal history with biodegradation controlled by temperature, nutrient availability to predict hydrocarbon composition of oil and its associated fluid properties, i.e., API gravity and viscosity.
DOVE
How Viscous is Your Oil at Reservoir Temperature? Find Out Here DOVE (Dead Oil Viscosity Estimator)
For most heavy oil and bitumen, dead oil viscosity is so high (greater than 1,000,000 cP at 25°C) that standard viscometers cannot measure the viscosity near reservoir temperatures (< 25°C for Alberta oil sands). To maximize sample throughput and minimize analytical error, labs commonly measure the viscosity of a bitumen at a suite of temperatures usually greater than 35°C and less than 80°C. These viscosity measurements must then be extrapolated to estimate true dead oil viscosity at low reservoir temperatures or at steam temperature for thermal recovery operations. Using a simple exponential extrapolation curve can result in significant over or underestimation of viscosity at the extrapolated temperature, BUT the tool below accurately estimates heavy oil and bitumen dead oil viscosity at a specified temperature (Walther's equation). Of course, it is best to measure viscosity as close to the conditions of interest as possible and over a wide range of temperatures to ensure optimal extrapolation to reservoir conditions. Gushor can measure from 12 to 200°C.
