Juan Andres Berrizbeitia

Senior Petrophysicist with 20 years of experience in the oil and gas industry, highly skilled in petrophysics, well log analysis, and seismic petrophysics. Experienced in petrophysical characterization using image and NMR logs, SCAL and RCAL core analysis, and pressure data. Has worked with over 200 wells performing petrophysical evaluation, elastic log editing using rock physics modelling and heuristic algorithm approaches, fluid modelling, and rock and fluid property sensitivities to understand its impact in the elastic properties of rocks. Integrates the products from the petrophysical characterization and rock physics modelling with the seismic information to de-risk prospects.

Has worked in carbonate and siliciclastic environments in basins around the world including Barents Sea, Norwegian Sea, UK North Sea, Gulf of Mexico, onshore Mexico, USA unconventional gas shales, Malaysia, China, Venezuela, and West Africa. Has conducted both post-stack and pre-stack seismic inversions in fields in China, Venezuela, USA, which provides him with a good understanding of an integrated reservoir characterization workflow.
