Resume/CV of Principal Partner

Dozie Okonkwo

Principal Partner, Kudoz Consulting. Leidschendam, The Netherlands. Sept 2003 – To-date

  • Responsibility: 
    Setting up a Consultancy whose objective is to serve the Upstream Oil and Gas Industry, particularly in the area of front-end work - integrated studies and activities involving specialists in the areas of subsurface engineering, well engineering, surface facilities engineering, operations engineering, marketplace assessments, economics, etc; prior to their final decision to invest in their hydrocarbon reserves development

The Shell Petroleum Development Company (SPDC) of Nigeria's Undeveloped Black Oil and Condensate-rich Gas Reserves. Rijswijk, The Netherlands. 2002-2003. 

Development Manager

  • Responsibility:
    Driven by License Expiry concerns, the principal partner took on the challenge of finding a rational, focused and timely manner to accomplish an integrated development of the as yet undeveloped liquid hydrocarbon reserves of one of the oil majors in the Niger Delta region​

    • Geographical spread of the Undeveloped Reserves:     +/-70,000 sq km

    • Terrain:   Land/Swamp/Immediate Offshore

    • No. of Fields:    200+

    • Listed Undeveloped Reservoirs:   +/-6,000

    • Size of targeted Reserves/Reservoir:

      • For Black Oil: 2.0 - 200 mmbbl

      • For C5+ -rich Gas: 1.5 - 100 mmbbl

    • Undeveloped Reserves of Black Oil and C5+-rich Gas:  >> 10 mmmbbl

  • The study conducted by the principal partner captured 90% of the reserves in 25% of the reservoirs, and its proposals included:

    • Integrated development of black oil and condensate-rich gas from the reservoir level all the way through central processing facilities to the storage and export points.

    • A dedicated C5+-rich export stream of a significant 8 year plateau, in addition to providing for the spiking of condensate into the black oil stream where the former could not economically be brought to join the C5+–rich export stream.

    • Export of the “lightened” black oil through 4 export points, i.e. 2 shore-based terminals and 2 FPSOs that also double up as FSUs.

    • The extended “first phase” of the development would capture some 71% of the undeveloped reserves of black oil and condensate-rich gas, with the rest employed in production plateau maintenance.

  • The proposals provided a basis for moving each of the 30+ Projects of different magnitudes to FID in a rapid and coherent manner so as maximize the reserves recovery prior to the License Expiry date of well below 20 years.

SPDC's Condensate-rich Gas Project, Rijswijk, The Netherlands. 1999 - 2001

Development Manager

  • Responsibility: 
    The task was to develop a condensate & liquefied petroleum gas business for SPDC and her joint venture (JV) partners that not only scaled Shell Group's economics hurdles, but ranked high enough in Shell’s E&P projects portfolio to be supported by the Group. The focus was on 60+ multi-reservoir fields located mainly in the Eastern portion of SPDC's Niger Delta concessions in Nigeria, with condensate initially in place (CIIP) of a few billion barrels.​

    • Developed proposals that established the foundation for a very attractive LPGs/condensate business for the SPDC joint venture       partners and the Nigerian Liquefied Natural Gas company (NLNG).​ The resulting business investments were in the following range:

      • A US $185 million scheme that would require only a limited investment – a single field, no gas injection facilities, but with C5+ spiked into the Bonny Light crude oil stream and the C4- injected into the NLNG gas supply pipeline.

      • A US $1.2 billion investment in the “base scheme”, involving two fields and dedicated field, transportation, process, storage and export facilities, and on which incremental developments from other fields could ride.


  • Worked with an integrated team of petroleum engineers, well engineers, surface facilities engineers, operations and external relations staff and an economist. Also included were NLNG staff and their technical advisers, Shell Group marketing staff in Singapore and London, ABB in The Hague and Granherne in London, as well as some of the key US companies in the NGLs business (Dynegy, Enterprise, etc) at Mont Belvieu, close to Houston.

SPDC's Shallow Water Offshore Fields (with EA Field as the first), Rijswijk, The Netherlands. 1997 -1999

Development Manager

  • Responsibility:
    EA Field was discovered in 1965 in some 13-27m of water (and the nearby Eja Field in 1968), but both remained undeveloped for over 30 years despite the drilling of 23 exploration/ appraisal wells in both fields. The task was to get the fields to scale the FID hurdle in the nearest future.

    • Brought the development to FID by September 1999, despite a reduction in the oil price screening value from $16/bbl to $14/bbl as a result of the 1998 oil prices collapse.

    • Business investment as a result of this project:

      • US $1.1 billion, with UTC going down from just under $7/bbl in the first quarter of 1998 to just below $4/bbl by FID date.

    • Worked with an integrated team of petroleum engineers, well engineers, surface facilities engineers, operations and external relations staff and an economist. Also included were the old “Shell Tankers” staff in London, ABB in Sutton, London and SBM in Monaco, as well as peer interactions with Shell staff in Rijswijk and Expro, Aberdeen.

    • Project Highlights: 

      • Increase in EA field ultimate recovery (UR) from 174 mmbl (when the last team to work on the field development concluded the exercise in 1996) to 325 mmbl at FID date.

      • Shell Expro, Aberdeen, assessed the entire system availability, from the wellhead to the FPSO export hoses, to be 96%. (95% is the normally accepted maximum system availability for such developments).

      • Of 48 wells to be drilled, 5 were designed to Level 6 multilaterals (SPDC was yet to drill her first Level 6 multilateral by then).

      • To minimize the number of conductors (and drilling platform size/number), 16 wells were designed to be “shared conductor” wells, the first such approach by any company in Nigeria.

      • The work laid the foundation for the first alternatively funded (AF) upstream oil and gas development in Nigeria.

      • For the local environmental conditions, the 1.4 million barrel FPSO to be built by Samsung of South Korea is designed to be moored with a Soft Yoke, complete with 360-degree weather-vaning capability, to a mooring platform with pigging facilities. All well testing will be carried out remotely at the drilling platforms, via fibre-optic cable borne signals, from the FPSO control room 4 to 6 kilometres away.

      • The field has since been developed and by mid 2003, was producing at over 100,000 bbl/d of oil, and still rising.



















SPDC's Western Division, Warri, Nigeria 1993 - 1997

Manager for Community Affairs, Safety, Health, Environment and Security (CASHES).

  • Responsibility:
    SPDC's licence to operate was closely linked to her management of community relations, the environment, security and road and water transport safety. This was because her activities in these areas brought her into direct, and sometimes abrasive, contact with the public. The challenge was to weld the disparate unit of 'CASHES' into some sensible and cohesive organisation.

    • Developed the concept of "Community Self-Help" Projects, whereby host communities were paid for organising themselves to execute their own chosen infrastructural projects.

    • Pioneered a Community Development approach, which resulted in cooperative community ventures between Shell and five communities by September 1997.

SPDC's Western Division, Warri, Nigeria. 1987 - 1992 

Operations Manager

  • Responsibility:
    The management of 1,300 operations staff (operations included production and maintenance, drilling, procurement, land/water/rotary wing transport, safety and environment).

    • Oversaw increase in drilling rigs at SPDC's western division from 3 in the late '80s to 7 by the beginning of the '90s, and increase in oil production from around 300,000bbl/d to just over 500,000 bbl/d of "Forcados Blend".

Shell International Petroleum Maatschappij (SIPM), The Hague, The Netherlands. 1985 - 1987

Liaison Engineer

  • Responsibility:
    Acting as the liaison between the engineering organisations in the Shell companies in the Far East/Australasia and SIPM in The Hague.

    • Guided and assisted the engineering organisations in preparation and presentation of their proposals (“Data Book”) to the center at The Hague.

    • Supported the addressing of engineering problems of those organisations from The Hague.
