About Christopher Sellar

24 years of experience in carbonate reservoir characterisation, exploration, appraisal, field development and production in the UAE, Oman, Yemen, Iran, Iraq and Kuwait. I have spent my career becoming an expert on the Geology of the Middle East.I am a hands on Geologist at heart who loves nothing more than spending time understanding rocks and sharing knowledge with colleagues from other disciplines. I'm committed to continuous learning. My passions are problem solving, reducing uncertainty, finding new opportunities, adding value to existing assets and maturing reserves. I have a proven track record of project and well delivery.I am a highly motivated, well organized, excellent communicator and presenter. I have held several roles as a mentor and coach to young and senior staff alike.I strongly believe successful projects are envisioned by inspirational leaders and delivered by highly integrated, passionate teams.

    Abu Dhabi, Abu Dhabi Emirate, United Arab Emirates
    - Responsible for the field development of fractured carbonate reservoirs in Atrush Block, in the Kurdistan Region of Iraq.- Managed the compilation of reservoir simulation cases from a new generation dynamic reservoir model for long term field development planning, reservoir appraisal design and reserves submission.- Responsible for production forecasting and optimization.
  • Adnoc Group
    Umm Lulu Reservoir Development Team Leader
    Adnoc Group Jul 2019 - Jun 2023
    Abu Dhabi, United Arab Emirates
    - Responsible for mid and long term field development in a super giant carbonate reservoir with multiple depletion schemes.- Led a multi-disciplinary subsurface and surface team conducting geoscience and reservoir engineering studies and constructing new generation reservoir geomodels for field development optimisation, reservoir appraisal design and long-term development planning.- Lead carbonate geologist on a field-wide reservoir characterization study. The study generated a new geological concept to explain reservoir property distribution tied to acoustic impedance and resulted in well placement optimisation and the definition of reservoir upside.- Mentor to young Emirati engineers and coach to experienced technical professionals.- The role required excellent stakeholder management, communication and presentation skills with JV partners.
  • Omv
    Department Manager Geology & Geophysics
    Omv Jul 2018 - Jun 2019
    Abu Dhabi, United Arab Emirates
    - Led a team of high performing G & G professionals in reservoir characterisation of operated and non-operated carbonate (UAE), fractured (Kurdistan) and Basement (Yemen) reservoirs.- Responsible for planning and implementing integrated multi-disciplinary studies of complex hydrocarbon reservoirs in OMV's U.A.E. concessions SARB and Umm Lulu Fields.- Key focus on understanding internal heterogeneity to optimize field development planning.
  • Omv Yemen
    Senior Production Geologist
    Omv Yemen Jul 2013 - May 2018
    Dubai And Abu Dhabi
    2017 - 2018 (OMV AD in Abu Dhabi):- Principle geologist responsible for reporting the subsurface risks, uncertainties and potential upside from carbonate reservoirs in business development projects.- Delivered G & G part of the OMV Technical Proposal for equity in the SARB/Umm Lulu offshore concession agreement. Ultimately the proposal resulted in OMV signing a 20% share in the concession. 2013 - 2016 (OMV Yemen in Dubai):- Developed a new geological concept for the fractured basement reservoir to optimise development drilling design.- Designed, managed and implemented an appraisal campaign in a tight, fractured sandstone reservoir. The project resulted in oil production from a previously unproduced reservoir.- Consultant carbonate sedimentologist for a Play and Prospect Study in South Fars (Iran): constructed regional common risk segment maps to derisk the placement of new exploration wells. - Described and interpreted more than 3000ft of core and built a regional conceptual geological model to challenge an exploration well placement in a challenging Eastern onshore Abu Dhabi exploration play.
  • Dubai Petroleum
    Senior Reservoir Geologist
    Dubai Petroleum Aug 2009 - Jun 2013
    Dubai
    - Constructed scenario-based Geomodels in Petrel testing petrophysical and structural uncertainty in Cretaceous carbonate reservoirs for two of the company’s mature oilfields. Proposed and presented new wells to management. Placed, landed and geosteered 14 successful horizontal oil producing wells as part of a mature field development. Managed all third party geological studies and integrated data into geomodels.- Generated a new geophysical interpretation of an appraisal/greenfield where shallow salt effected the depth conversion. The work led to an increase in STOIIP, the placement of expanded facilities and the drilling of a successful oil producing step out well.- Led a regional mapping project studying volumetric and productivity potential to hydraulically stimulate source rock/unconventional reservoirs.
  • Rak Petroleum
    Reservoir Geologist
    Rak Petroleum May 2006 - Jul 2009
    Dubai
    - Responsible for the company’s geological interpretation in exploration and production blocks in northern Oman.- Designed and managed third party studies to maximise data acquired from core, BHI and while drilling for fracture characterisation.- Developed regional facies models of key reservoirs for input to prospectivity mapping as part of the exploration campaign in Oman.- Jointly responsible for picking two economically successful step out well locations in a fractured carbonate oil reservoir under early development.
