•Delivered field studies on several conventional/unconventional projects of Pemex that derived in the production optimization over 30% for the Nejo & Miquetla fields described below.•Nejo Field (415+ wells producing gas/condensate/volatile oil): defined a Dynamic Flow model & depicted a hypothetical Formation Pressure Profile of the different blocks/paying zones using a non-conventional way. Identified/quantified reserves of potential up hole/downhole producing layers.•Miquetla Field (122+ wells producing gas/black oil): identified some bottlenecks & established strategies with the aim of optimizing production & increasing the Recovery Factor of the field.•Pimienta Shale (unconventional resources): defined the best practices to be applied on the drilling/completion of wells on some hot spot areas based in the Prospectivity Evaluation made up from available seismic/core analysis/well log data. It was considering key factors like Reservoir Quality/Completion Quality/Operation Efficiency to optimize productivity of wells, and using some drilling/completion process, production profiles & performance (IP/EUR), and assessment of Economics coming from several analog wells located in the Eagle Ford/Bakken/Niobrara/others US Shale Plays.•Ayin Field (GOM offshore field with 5 wells producing from clastic/carbonate): worked on the identification of the driving mechanisms of producing layers by mean of Material Balance assessment & further generation of a Dynamic Flow model of the field. Despite of some challenges regarding behavior of clastic/carbonate formations and presence of water, formulated a development plan of the potential zones. Generated a reservoir optimization strategy supported with a continuous reservoir monitoring in order to get the most of production from the identified pay zones.•Handled/evaluated dynamic data in the areas of Well Performance/Production Analysis/Material Balance/Production Forecasting/DCA Analysis/Well Productivity/& Damage Assessment.

It covered some Federal & State Regulations regarding HSE issues, revision of several kinds of Workover Operations and Equipments/Tools to be used, Sand Production & Remediation, revision of History of many neighboring wells, Reservoir Geology, Evaluation of three different Producing Intervals, Design & Implementation of an Artificial Gas-Lift Method based on the Sensitivity Analysis to several key factors such as: Reservoir Pressure/Reservoir Permeability/Injection Pres./Injection Rate/Water Cut/Tubing ID.

Houston (Texas), Mexico, Venezuela, Colombia, Latin America

•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.

Balikpapan, Indonesia

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.
