High Definition vs. Conventional 3D Survey Cage Match: Pre-Stack Inversion Benchmarking Test


Elastic parameters (Vp, Vs and Rho (e.g., density)) from our log data are critical components of our subsurface models. They’re used to estimate geomechanical and reservoir properties that are key to enhancing production and lowering costs. Equally important is being able to reliably distribute these log-derived values in three dimensions. This can be aided by using 3D seismic data where Vp, Vs and Rho are estimated via pre-stack inversion. This paper isolates the role seismic acquisition plays in providing reliable estimates for these elastic parameters from a pilot SM energy conducted in our South Texas asset where a HD3D seismic survey was acquired over a legacy 3D survey and compared. This study quantifies the uplift provided from high-density 3D seismic data in estimating Vp, Vs and Rho when compared to estimates from the existing lower source/receiver density, legacy seismic survey. Our benchmarking study showed an increased in the correlation coefficient, when comparing the density estimates from the inversion to log density data, from 0.68 to 0.74. The other elastic properties show substantially more uplift as well. 

Speaker Bio:   

TONY P. LUPO Has worked in the energy sector for 20+ years and is currently working for SM Energy as their chief geophysicist at the corporate headquarters in Denver where he is actively involved in managing various technical programs, data science initiatives, mentoring and recruiting. Prior to that, he was Vice President of Geophysics at Fossil Creek Resources in Arlington, TX and before joining Fossil Creek Resources he worked in Samson Resources’ Mid-Continent division where he helped establish enhanced acquisition and interpretation technologies prospecting for various deep gas plays that were a significant component of its portfolio. Lupo began his career at ConocoPhillips working with various assets teams, including West Africa, the Gulf of Mexico, Alaska and the Mid-Continent. As part of ConocoPhillips’ Integrated Geologic Analysis group, he focused on advanced interpretation techniques, rock physics, high-resolution seismic acquisition and processing, particularly in the Mid-Continent, where his efforts significantly reduced risk in key stratigraphic plays and were used to help identify several previously undocumented plays.

Lupo holds a B.S. in Geology from Grand Valley State University and an M.S. in Geophysics from New Mexico Tech. He has recently been selected and confirmed as a member of the Board of Directors for the Society of Exploration Geophysicists Foundation and has published various papers on topics that include machine learning, seismic acquisition and seismic reservoir characterization.

Tony Lupo enjoys mountain biking, reading, camping, hunting, fishing and terrorizing Denverites in his 1967 Camaro.
