  • Waterflooding Optimization with DMS Eclipse• Production Optimization for unconventional wells with Quiklook-DMS.• Calculating gas reserves for unconventional wells with limits.• Building WAG simulation model on Nexus to support a patent process.• Optimization WAG parameters with DMS and Nexus• Building Multi-Reservoir Production & Gas Life Network on Nexus and GAP. Nodal Analysis with Prosper.• Economic evaluation of oil and gas reserves using Aries & decline curve analysis. Show less • Providing technical support to global clients by evaluating workflows with Nexus, VIP and DMS.• Assisting global clients troubleshooting integration issues with other third party applications such as Eclipse, Mbal, Prosper, GAP, CMG including STARS.• Evaluating different scenarios to optimize models and deliver the appropriate solutions on time.• Providing recommendations for simulator - software enhancements by submitting report to the software developers.• Evaluating new software versions by testing the applications and providing feedback to developers.• Converting from Eclipse Simulation Model to VIP Simulation Model or/and Nexus Simulation Model• Converting from GAP Model to Nexus Simulation Model• Building example simulation models to reproduce software defects Show less • Ongoing reservoir management for the reservoirs. Worked with a team of geoscientists, drillers, and completion engineers to optimize reservoir development. Successfully proposed water injection, gas injection and steam injection location based on modeling work to delay water breakthrough while still providing needed pressure support to increase production. Recommendations have contributed to the reservoir performing significantly beyond expectations.• Compositional and economical analyses carried out which influenced the operator in the ongoing appraisal of the field.• Evaluation of light & heavy oil reservoirs for company working with major energy firm, the operator of the field. Prime focus was on operating issues, such as well locations and gas/water injection, and developing strategies for increased ultimate recovery. Constructed Eclipse, VIP, Nexus & CMG reservoir models as a tool for discussions with the operator. Along with other members of the team, influenced partner to modify the project development with positive results for wells.• Applications were implemented using primarily the Eclipse simulator & Nexus/VIP simulator with support from Prosper, MBAL, and PVTSIM software. Show less • Provided assessment as an on-site consultant of the DIMS perforation data bases, in the main offices of PDVSA Maturín, Punta de Mata, San Tome and El Menito.• Supported in the planning of well drilling proposals during 2004 in eastern Venezuela, using the following applications: Compass, CasingSeat, StressCheck and WellPlan.• Participated in the production of maps for the project of Decision Space that is presently developed in PDVSA Punta de Mata.• Supported Perforation Engineers of PDVSA in the use of Presgraf application, to calculate pore pressure and fracture gradient.
