Experience

• 

  Maraven S.A.

  Jul 1992 - Sept 1992

  Intern

  Analyzed and developed a non-adiabatic computer simulation of the Boscán field (now partially owned and operated by Chevron) for the oil, gas, and associated water, to estimate the tolerance of the network at different levels of production (from 70,000 bopd to 115,000 bopd). The project involved studying the fluid mechanics of heavy crude (13 API), as well as crude sampling and data collection.
