“Rock and fluid characterization strongly affect in-place volumes, recovery factors, injectivity/productivity, and deliverability. Therefore, accurate rock and fluid characterization are key for minimizing technical risks and maximizing the asset value.” - Honarpour, et al, SPE 103358
Multi-scale rock properties from Ingrain helps maximize hydrocarbon recovery and reduce risk in technically challenging reservoirs

Digital Rock Physics Overview

Step 1: Macro CT scanning of core for identifying sampling locations: • CoreHD® High Definition CT imaging and logging of whole core • Creation of Continuous Core Viewer movie, CT Borehole Image, Density Log and Atomic Number Log • Sample locations identified, samples taken
Step 2: vRock® digital reservoir rocks created and basic rock properties computed: • Micro/Nano CT or FIB imaging as required • Segmentation and image processing, creation of vRock digital reservoir rocks • Computation of basic rock properties (porosity, absolute permeability in x,y,z directions) • Selection of vRocks for advanced rock properties
Step 3: Advanced rock properties computed from vRocks®: • Grain size distribution • Elastic properties (including Bulk, Young & Shear Modulus, Poisson’s Ratio, Vp & Vs) • Formation factor • Archie’s cementation exponent “m” and saturation exponent “n” • Relative Permeability • Capillary Pressure

If whole core is not available, Ingrain can process plugs, cuttings and fragments
![Page 11: SCAL in Shale - Ingrain, Inc. in Shale Over 4000 rock samples processed and 125 commercial jobs have been completed in the past 18 months Ingrain has digital rock physics labs in Houston](https://reader031.vdocuments.mx/reader031/viewer/2022022516/5b0003107f8b9a89598bf206/html5/thumbnails/11.jpg)
During scanning, the energy emerging from the other side of the sample is converted into visible light and recorded as a digital image.
Step 2: Create vRock® digital reservoir rocks
![Page 12: SCAL in Shale - Ingrain, Inc. in Shale Over 4000 rock samples processed and 125 commercial jobs have been completed in the past 18 months Ingrain has digital rock physics labs in Houston](https://reader031.vdocuments.mx/reader031/viewer/2022022516/5b0003107f8b9a89598bf206/html5/thumbnails/12.jpg)
Ingrain images reservoir rock samples at the resolution needed to compute basic and advanced rock properties
When sampling and imaging, Ingrain uses the largest volume and lowest resolution (and therefore largest field of view) that will permit accurate computation of rock properties and fluid flow.
