Gustavo Carpio

Gustavo Carpio is a Senior Technical Advisor for Ingrain, a Halliburton Service. For the past 11 years he has contributed to Ingrain’s technological and commercial development, coauthoring several patented methods for the characterization of tight reservoir rocks and participating in the evaluation of unconventional resource plays in North and South America. Presently, he is focused on the integration of Digital Rock Analysis, Core, and Wireline data.

Mr. Carpio holds a B.S. in Geology from the University of Houston and is a member of the AAPG, HGS, and SPE.


Sidewall coring provides geologists, petrophysicists, and reservoir engineers with a cost-effective way of increasing formation knowledge through the retrieval and direct analysis of reservoir rock. However, without careful selection, this form of discontinuous sampling can lead to misrepresentation of subsurface properties. For this reason, sidewall core selection from wireline logs and core screening become crucial steps in formation evaluation.

We present a workflow that addresses the challenges of distribution and representativeness of rotary sidewall cores. The workflow begins with a data-driven analysis of wireline logs to and capture variations in an interval of interest, identify electrofacies, and optimize sample distribution.

The workflow continues beyond core extraction with Dual Energy CT – a rapid, non-destructive core logging and imaging method that captures the degree of fine-scale heterogeneity in each core. The workflow provides valuable insight in a rapid timeframe and delivers data that can be used to better design subsequent digital and physical core analysis programs.
