- Managed 3 hydropower plants (30 MW capacity) and associated distribution networks (120 km MV, 350 km LV) run with 150 people, delivering power to nearly 20,000 clients in North-Kivu- Digitalized various administration & operational processes to improve follow-up and cost- Reorganised operations and sites to increase efficiency and reduce cost (e.g. reduced OPEX from $1.7 to $1.2m (-30%) on main operating site between 2019 and 2020)

- Managed the Emeraude offshore oil field producing 12,000 bopd with 35 platforms & 90 wells, run with 115 people- Fought production decline through well and process optimisations- Reduced work-over frequencies through improved completion designs (Sucker Rod sizes, tubing composition), optimised downhole pump selection, pump-off detection)- Reorganised working schedule & logistics allowing 10% increase in effective working time

-Accompanied operational transition of TSP assets acquired from Repsol to Perenco - Reviewed and supported operations, identified and implemented integrity, process and well optimizations on field producing 11,000 bopd.- Managed teams of production operators and maintenance technicians- Trained field engineers and site managers in the France head-office as group gaslift expert

- Performed production & reservoir reviews- Modelled reservoirs in IMEX- Prepared drilling campaign for Cameroon: 11 side-tracks identified, production results between base and high case forecasts.

- Monitored and optimized an offshore field with gas lift, ESP and water injection wells- Planned and analyzed slickline operations (MPLT, scraping…) data acquisition, acid stimulations…)- Prepared future operations campaign (calipers, MPLT, stimulations, activation conversions...)

- Provided technical support to subsidiaries- Reviewed the technical side of projects from subsidiaries needing authorization for expenditures

- Monitored and optimised water injection and gas lift wells- Prepared pilot ESP project: selection of candidates, design, call for tender…- Performed downhole and surface optimization studies on short & mid-term (e.g. compression needs)

- Optimised production through modelling of wells and surface network (Prosper, Gap, OpenServer)- Created various automated monitoring tools: productivity index calculation, tests validation, sand database…

Internship - Kinshasa- Assessed of the municipal waste situation in Kinshasa.- Reviewed of the local actors and international organizations.- Managed a team of three investigators to achieve field work.
