Sr. Reservoir Engineer

**Company**
QatarEnergy is an integrated national oil corporation that stands at theforefront of efforts for the long term sustainable

development,utilization and monetization of oil and gas resources in the State ofQatar.In its efforts to become one of the

best national energy companies inthe world, QatarEnergy's activities and those of its subsidiaries andjoint ventures,

encompass the entire spectrum of the oil and gas valuechain locally, regionally, and internationally.They include the

exploration, refining and production, marketing, andsale of oil and gas, liquefied natural gas (LNG), natural gas

liquids(NGL), gas to liquids (GTL) products, refined products, petrochemicals,fertilizers, steel and aluminum. As an

integrated corporation,QatarEnergy's activities also include marketing and sale of oil and gasand other various

products.QatarEnergy's operations and activities are conducted at various onshorelocations, including Doha, Dukhan and

the Mesaieed and Ras LaffanIndustrial Cities; and at various offshore areas, such as offshore oilfields production stations,

drilling platforms, Halul oil export island,and the North Field, which is the largest single non-associated gasreservoir in the

world covering an area of 6,000 square kilometers. Theutilization of this field’s massive reserves has become a

primarynational goal to continue the development and prosperity of the country.QatarEnergy pays the utmost attention to

the health and safety of itsemployees, contractors, visitors and the local communities where itoperates. From drilling to

construction, operations to decommissioning,QatarEnergy's health, safety and environment policy forms an integralpart of

the corporation’s daily business and long term planning.QatarEnergy is committed to contribute to a better future by

meetingtoday’s economic needs, while safeguarding our environment and resourcesfor generations to come. Thriving on

innovation and excellence,QatarEnergy is bound to the highest levels of sustainable human, socio-economic, and

environmental development in Qatar and beyond.

**Department**
OPERATED ONSHORE OIL FIELD DEVELOPMENT

**Primary purpose of job**
Undertake Reservoir Engineering studies of the QP operated Dukhan oilfield to optimize field development plans, support

simulation model maintenance, analyze reservoir and well performance data, develop reservoir surveillance programs and

conduct reservoir management activities, including supporting planning and activity on CO2 WAG pilot. Prepare

detailed/integrated development plans for underdeveloped hydrocarbon resources and participate in interdisciplinary

reservoir study teams.

**Experience & Skills**
Principal Accountabilities

1. Modelling, monitor and assess CO2 WAG EOR performance.

2. Help develop and deliver optimized mid / long term strategic and tactical plans for the Operated Onshore field Assets

3. Perform the annual review of reserves, generate long-term production/injection forecasts for Asset Planning, Business

Planning and drilling/workover schedule.

4. Plan and supervise the acquisition (and perform analysis/interpretation) of Reservoir Engineering data from new and

replacement wells for updating dynamic reservoir simulation models and determining optimum development plans and

drilling targets. Ensure all data and analysis is input into integrated reservoir/field development studies.

5. Maintain, develop and run 3D multiphase black oil / compositional dynamic reservoir models for mathematical simulation

of reservoirs and field development planning

6. Develop / contribute and integrate Reservoir Engineering inputs into the short term (drill/replacement well projects,

workover projects & drilling/workover operations), medium term (reservoir voidage management) and long term (field

development and asset value optimisation) activities.

7. Identify target reservoirs/reservoir layers and determine well-reservoir contacts for new/replacement

vertical/deviated/horizontal drill projects into multi-layered heterogeneous reservoirs to optimize field development.

8. Prepare detailed, integrated development plans for undeveloped hydrocarbon resources.

9. Provide input to existing reservoir exploitation with regard to implementation of longer term reservoir management plans.

Ensure surveillance programs are efficient and effective. Advising on reservoir management policies and well production

limitations.

10. Lead reservoir performance surveillance review sessions with multi-discipline teams.

11. Coordinate and follow up the execution of reservoir-wide pressure transient analysis surveys.

12. QA/QC Reservoir Engineering data and maintain Reservoir Engineering databases including real time data links

13. Provide on-the-job coaching and mentoring of Qatari staff

14. Share and leverage knowledge and skills across Operated Onshore Field subsurface teams
