Experience in the O&G industry, specifically in exploration and field development. Has worked for operators and service companies in supervisory or contributory roles doing: borehole seismic (VSP, check-shot, salt proximity and synthetic seismograms), 2D/3D seismic data processing, AVO, AVAZ, seismic inversion, and rock physics. Designs and implements workflows to meet specific geophysical objectives and develops the necessary software when this is not commercially available.
Started in GSI as field QC for vibroseis crews in Mexico. Later became Area Geophysicist for Mexico’s GSI’s office. When transferred to Halliburton Geophysical in Houston (1989) worked in surface and borehole seismic data processing. In 1994 moved to “The Andrews Group International” (AGI) where his duties as Senior Geoscientist included preparing and teaching Geophysics (data processing) courses for Mexico and South America. Later became technically responsible for Houston’s and Mexico’s seismic data processing operations.
In 1999 AGI was acquired by Core Laboratories where Alvaro started the Advanced Reservoir Geophysics group which he managed. During this period, production workflows to reduce risk in estimation of petrophysical properties using seismic data through rock-physics modeling, AVO and seismic inversion were implemented. Starting in 2000 and until 2012 he managed small groups specializing in well-seismic calibration and estimation of rock properties (impedances, density, etc.) to help reduce risk in the estimation of reservoir and geo-mechanical properties (porosity, lithology, fluids and fractures’ properties among others).
From 2010 to 2016, while at Geokinetics and Hess Corporation, created methodologies to reduce risk in sweet spot identification within unconventional plays. These included those for characterizing fractures and brittleness as well as qualitative estimates of Total Organic Content (TOC). Disciplines in these methodologies include: fit-for-purpose seismic data processing, pre-stack inversion, AVO, AVAZ, high resolution velocity estimation, rock physics modeling and converted wave (PS) seismic data amongst others.
At Hess Corporation, he supported conventional and unconventional teams through consulting and providing products to qualitatively estimate reservoir and geo-mechanical properties.
