Rio De Janeiro, Brazil

Volunteer work for Brazil chapter of the Society of Petrophysicists and Well Log Analysts, supporting local activities and planning and execution of 65th SPWLA Symposium.

Rio De Janeiro, Brazil

Perform comprehensive petrophysical studies and advanced analyses by integrating logging tool responses, rock, fluid and production data for formation evaluation and reservoir surveillance for Peregrino Asset - Campos Basin, leading integrating efforts as needed, to ensure petrophysical properties and uncertainties are adequately incorporated in dynamic and static models. Develop and lead data acquisition strategy for new drill wells, collaborating with other subsurface disciplines to capture their requirements. Liaise with logging companies and in-house authorities, to ensure proper logging data acquistion and execution is in accordance with Equinor's best practices. Geo-steer horizontal and highly deviated wells to meet target reservoirs and follow up wellsite geology operations.Prepare technical report and collaborate with all stakeholders to integrate petrophysical data and study results into field development strategy, making recommendations and providing technical analyses to team, project leaders and line management.

Rio De Janeiro, Brazil

Project Lead responsible to prepare detailed Wireline and LWD programs in conjunction with Subsurface and Wells Team making key operational decisions related the design and implementation of petrophysical data acquisition strategies to deliver safe and optimized operations, ensuring to meet or exceed operator’s requirements. Coordinate activity with local customers, as PETROBRAS, LIBRA, SHELL and ENEVA, supporting LWD and wireline operations in Real Time, performing logging quality control and advanced processing and interpretation formation evaluation data in siliciclastics and carbonates reservoirs.

Rio De Janeiro E Região, Brasil

Perform open and cased hole log analysis and interpretation with hands-on experience with petrophysical softwares, integrating technology and answer products to provide reservoir evaluation. Working on Pre-Salt area (Libra, Lula, Búzios, Sapinhoá and Carcará fields) with focus on client engagement, collaborating to deliver integrated reservoir characterization solutions that drive increased production and reduced development risk. Real time operations support during wireline formation testing and sampling.
