PROFESSIONAL SUMMARY
Oil and Gas Well and Reservoir Manager. Mitigation of risk together with realization of potential from
subsurface oil and gas assets.
• Oilfield surveillance. Selection and acquisition of oilfield data options that are relevant for the situation and
context at hand. Its conversion into useful information, and determination of what requires accomplishment
to make money safely and to optimize asset value.
• Competent assessment of possibility and avoidance of unnecessary risk, particularly in mature oil and gas field
environments.
• Programming and operational surveillance, and day-by-day management of drilling, work-over, and/or other
operational oil/gas field interventions.
• Business performance analysis and dissemination of results from oilfield intervention works.
• Technical expertise in Production Technology and Reservoir Management. Particularly in disciplines related to
surveillance, reservoir delineation, recovery, flow assurance, well and barrier integrity, inflow and lifting
performance.

PROFESSIONAL E&P WORK EXPERIENCE
Nov 2011 to Feb 2016. Maersk Oil, Copenhagen, Denmark.
Lead Petroleum Engineer/Lead Production Technologist.
Principal author of the company’s new surveillance strategy along with new definitions of production
gain categorizations. This caused the effect of technical disciplines accomplishing engineering (instead
of guess-) work, enabling the planning and targeting of specific works towards the delivery of desired
production delivery outcomes. The effort resulted in turn-around performance (surpassing of well
integrity and production efficiency targets) that was repeated consistently for multiple years.

gillesnfio@gmail.com,
Oct 2009 to Sep 2011. OMV/Petrom Romania.
Chief Petroleum Engineer.
Particularly challenging circumstance characterized by paper-based and corrupted data in the oldest oil
production province in the world. Significant cultural, business-performance, teamwork, competency,
and language challenges. Achieved greater focus toward well, facility and reservoir remediation.
Restoration/Optimization a greater component of the company agenda at present.
Nov 2000 to Oct 2009. Shell International Exploration & Production (SIEP)
April 2008 to Sept 2009
Lean Well and Reservoir Management “WRM”
Member of an exceptional 7 member team based in Shell central offices in Rijswijk (Netherlands) with
the purpose of establishing SIEP WRM standards and developing region specific improvement
programs. Acquired comprehensive training and references relevant to modern oil/gas field
management practice.
Jan 2005 to Mar 2008
Sabah Shell Petroleum Company, Miri, Malaysia. “Double hatting” role as Shell International
Exploration and Production staff.
Petro-physics Discipline Lead
Sabah mature oil assets, deepwater development, and Changbei tight gas development (staff supervision
across 3 separate development teams in the two countries of China and Malaysia). Participated in the
respective leadership teams, contributed supervisory roles, technical QA/QC, and guidance for up to 15
local and expatriate staff.
Sabah Asset Reservoir Management Team Leader
Coordinated the reservoir management efforts of a multi-disciplined team of 12 staff members.
Encouraged the practice of well-by-well and specific reservoir management reviews. Re-established a
long de-prioritized practice of regular production and saturation surveys (i.e. PLT and TDT/CO logs),
and organized specialized training for local Petrophysics and Production Technology staff from both
Malaysia and Brunei. Established numerous options from which business plan actions could be selected
for the derivation of production, spending, and activity targets for the company aiming to optimize
short and long term asset value.
Nov 2000 to Dec 2005
Contractor Role, Sarawak Shell BHD, Miri, Sarawak, Malaysia.
De facto team-lead of St. Joseph oil field (700 MMstb STOIIP producing some 40 Mstb/d).
Successfully determined actual vertical and areal sweep efficiency that was occurring behind a gas-flood
front in a gas injection pressure maintenance project. Derived technical arguments and derivation of
appropriate surveillance and interventions upon the compression and gas-injection system that both
improved the reservoir sweep and reversed the production decline for 3 years. Team focal point for six
major infill-drilling campaigns (21 new horizontal wells and 15+ work-overs, offshore).
May 1999 to Dec 1999 Contractor - Santos Limited, Adelaide, Australia.
Established key reservoir delineation parameters by integrating the available data for the first time. The
work was endorsed by the National Centre for Petroleum Geology and Geophysics (NCPGG) at the
University of Adelaide, Australia. The work resulted is a successful tight gas re-development project in
the Permian Cooper Basin of South Australia.

Aug 1997 to Apr 1999 Contractor - Woodside Energy Limited, Perth, Australia.
Bolstered simulation based forecasting by correcting rock wettability estimates that were originally
made, resulting in reduced Capex spend for planned water handling for an offshore FPSO. Contributed
to unitization efforts resulting in a preservation of a multi-million dollar tax credit for the Wanea-
Cossack oil fields.
1992 to 1997 Expatriate staff Petro-physicist
