Recent work

Reservoir Engineer, Blocks XIII-A, XIII-B and VII, Peru, March 2019 - Present

Responsible for reserves estimation and depletion planning using decline curve analysis (DCA), Material Balance, and numerical simulation tools (ECLIPSE, INTERSECT, CMG).

Implemented advanced reservoir surveillance integrating well testing, pressure transient analysis (PTA), PLT, and waterflooding analysis to optimize sweep efficiency and maximize EUR.

  • Designed and executed extensive drilling (40 wells) and workover programs (90 operations), leading water injection strategies for enhanced recovery.
  • Developed analytical and numerical reservoir simulation models (SAHARA, KAPPA, Petrel RE) for secondary recovery optimization and EOR evaluations.
  • Led subsurface analyses for international bidding rounds, successfully securing a 30-year concession for Block VII with an extensive development plan.
  • Performed comprehensive reservoir risk assessments to mitigate uncertainties and optimize well performance.
  • Provided cross-disciplinary technical support, conducted economic modeling for asset valuation, and authored technical reports presented at Technical Committee Meetings.
