Bringing Core Analysis Into The Digital Age
When lab results and log measurements are inconsistent, inconclusive or conflicting, it can be an ‘all hands on deck’ exercise to unravel the data and get to the truth. However, in many cases the necessary data points such as wettability, capillary pressure and relative permeability can be months, if not years, away from input to the reservoir model. Guesstimates can lead to over- or under-inflated evaluations of recoverable hydrocarbons and can greatly impact production predictions – ultimately compromising decision-making that effects CAPEX investments in downstream infrastructure.
Digital rock is a relatively new discipline that advances traditional core analysis by using high-resolution microscopy imaging systems and 3-D visualization techniques to analyze the microstructural rock features of core samples. Using process- or image-based modeling, digital rock creates an accurate representation of the pore-scale internal rock architecture in 3-D by incorporating micro- and nano-scale structures such as grain size, contact angles, pore network connectivity, mineralogy, and clay content (to name a few). The models can be used to generate multi-phase fluid flow simulations that provide advanced rock and fluid properties in less time than traditional measurements – a first look at the dynamics contributing to ultimate recovery.
In this webinar, you will:
• Learn about digital rock modeling and how simulated multi-phase flow properties can deliver answers faster and with greater insight than traditional measurements.
• Discover the many instances where digital rock analysis can provide answers which are either difficult or impossible to obtain by more conventional methods.
• Understand how the combination of imaging and pore-scale modelling can lead to more accurate estimates of properties like residual hydrocarbon saturations.
