The Ingrain Difference

 

Ingrain's Industry-Leading Digital Rock Physics Labs

Ingrain is the oil and gas industry's leading fully-integrated digital rock physics company, providing lab services on a global basis.  Ingrain's technical leadership is built on a foundation of: 

  • Rock physics, geoscience and engineering expertise

  • Advanced 3D imaging capabilities

  • Proven computational methods

  • Scalable high-performance computing capacity

  • Rigorous quality control and a commitment to HSE

 

Ingrain digital rock physics labs provide advanced rock properties analysis for sandstones, shales, carbonates (including micritic), tight gas sands and oil sands. Using whole core, core plugs or drill cuttings, Ingrain can deliver accurate results as fast as 14 days. Ingrain can provide accurate results using samples from core repositories that have been altered by drilling fluids. Full SCAL properties can be provided from drill cuttings where whole core or core plugs are not available.


What makes Ingrain's digital rock physics lab different from a physical core analysis lab?

Digital rock physics was developed because true heterogeneities that are commonly present in most rocks are often masked by the averaging effects of plug-scale laboratory analyses and/or 2D visualizations such as thin sections and scanning electron microscopy. Further, physical lab tests have been shown to be prone to error and time-consuming to conduct in low permeability rock types. Finally, digital rock physics is uniquely capable of quantifying the contribution of micro-porosity to fluid flow in rocks where multiple porosity systems are present.

Obtaining and understanding the physical properties and fluid flow characteristics in reservoir rocks (clastics and carbonates) accurately, and in a timely basis, remains a challenge requiring special capabilities. What makes Ingrain's digital rock physics lab different from a physical core analysis lab?


Ingrain's "pore to core" workflow enables more accurate upscaling of reservoir rock properties

Ingrain’s multi-scale digital rock physics workflow seeks to rapidly identify lithofacies from CoreHD® whole core CT scanning and logging. SCAL sampling locations are then selected such that an optimum number of samples can be taken to represent key rock units. Miniplugs are then taken for high-resolution CT scanning and vRock® creation. Rock properties and fluid flow characteristics are then computed for each rock unit. The identified rock types can then be upscaled to the whole core, and from there to the reservoir, by the client.

Ingrain is the only DRP provider that integrates whole core CT data with pore-scale rock properties compuations. The combination of these two key technologies means optimized selection of sampling locations, followed by computation of rock properties that can be quantitatively upscaled to the core. The characterization of rock units within the whole core can then be tied back to the reservoir model through logs and seismic.

 

Ingrain dramatically reduces SCAL costs and delivers fast results

Phyiscal SCAL experiments are costly, can be difficult to conduct and are prone to inaccuracies. In the phyiscal lab, many core plugs must be cut to provide an acceptable pool from which plugs are selected for SCAL work. Typically SCAL tests are run two or three times to provide one result that is acceptable to the reservoir engineer.

Ingrain's digital rock physics lab provides full SCAL results within a matter of weeks while reducing the cost, waste and error resulting from phyiscal core analysis methods. When taken as a whole, the digital rock physics SCAL services provided by Ingrain are a dramatically better value than physical SCAL programs.

  • Ingrain's process works with sidewall cores and drill cuttings, which means rock properties can be obtained for wells in which coring is not an option or logs cannot be run. Ingrain’s CT scanning and proprietary computational algorithms combine to allow the computation of rock properties from drill cuttings or small rock fragments (1mm in size).

  • Accurate measurements in difficult formation types (oil sands, shales, heavy oil bearing carbonates, low perm rocks)

  • Rock samples are digitized and archived as vRock® digital reservoir rocks (segmented 3D digital images) thus permitting the client to build a digital rock physics database

  • vRocks® are reusable, enabling "what-if" analyses under varying reservoir conditions. CT scanning does not destroy the sample but instead creates a permanent, resuable digital object

  • The ability to provide the rock properties and multiphase fluid flow information from core samples and drill cuttings in a timely basis (average turnaround time is 30 days) provides tremendous advantages in making decisions.

  • Results are ready to integrate with existing reservoir models

  • The ability to discriminate and analyze micro-porosity at the nanometer scale to better understand and upscale dual-porosity systems

  • Additional information to understand the results of physical lab tests when unexpected outcomes emerge
