•For many clients in Latin America, handled and evaluated dynamic data in the areas of Pressure Transient Analysis (PTA), Rate Transient Analysis (RTA), Well Performance (Nodal Analysis-inflow/outflow curves), Production Analysis (PA), Material Balance, Production Forecasting, Decline Curve Analysis (DCA), Monitoring of Reservoirs, Numerical Simulation, MR-PLT Planning/Interpretation, Well Productivity, and Damage Assessment. •Ran training workshops in those areas using the Kappa suite (Saphir, Topaze, Diamant, Rubis, Emeraude, Amethyste). Based on the identification and diagnosis of specific problems, submitted recommendations, which resulted in the optimization of the Oil &Gas production over 30%, the improvement of the well productivity, and development of history matching and production forecasting on a weekly or monthly basis as a decision tool. Awarded by PDVSA with a certificate as “Instructor for PTA & PLI Technology Days” during one of these workshops. •Initiated, led, and developed corporate contracts for Kappa in Latin America. Secured long-term contracts with PEMEX in Mexico, PDVSA in Venezuela, and ECOPETROL in Colombia. Consistently surpassed annual goals/performance objectives.

Reservoir Engineering Advisor on the TOTAL-Indonesia Technical Assistance Contract (Offshore Tunu field)•Performed reservoir surveillance plans within a multidisciplinary field study team on the TOTAL-Indonesia Technical Assistance Contract, including: planning, QAQC, and acquisition/evaluation of PT & MR-PLT jobs, and conducting material balance, well performance optimization studies, well productivity analysis, and dynamic reservoir characterization, and extending results into the larger reservoir simulation model. The execution of these studies allowed a substantial increase of production 25 to 30%, by the addition of new producing zones, and the identification of some problems, which were properly resolved. Identified/evaluated reserves, performed allocation of production and production forecasting.•Besides the Tunu (gas + condensate) field that is operated by TOTAL in Indonesia, I was involved in some kind of studies and evaluations regarding the Tambora (oil + gas), Handil (oil), Bekapai (oil), and Peciko (gas + condensate) fields in Indonesia.
