Senior Reservoir Engineer

Job Purpose

Maximize production from Upper Mauddud, Hith, Khatiyah and other under-developed reservoirs and ensure available water disposal capacity at all times in Umm Er Raduma formation through effective reservoir management best practices, reservoir surveillance plans, opportunities identification and maturation.

Utilization of classical reservoir engineering, full field models (IX) and 4D Seismic to optimize voidage replacement, non-conformance mitigations and increase recovery.

Doha (Qatar) office
Standard office hours, 5 days a week

Key Accountabilities

• Identification, planning and close follow-up the reservoir surveillance plans for UMO reservoirs (65 existing wells and 60 future wells)
• Perform subsurface studies to improve production and injection (slugging, decline analysis, GL, ..)
• Identification and follow-up of reservoir management activities to maximize production, voidage replacement improvement, and reduce the decline rates for UMO wells

• Perform simulation and special studies related to well performance improvement initiatives
• Build and update UER aquifer model and optimize water disposal scheme (current and future projects)
• Opportunities identification and maturation to FID (RD Workovers, Tubing Change-outs, Integrity WO, Stimulation...) for production and injection improvements in collaboration with Field Operations, Drilling & Wells, and New Well Delivery
• Timely generation of monthly unconstrained profiles for short term production forecast (Rolling Forecast)
• Perform new wells and work-overs post-mortem synthesis in collaboration with New Well Delivery, and Reservoir Development & Growth teams
• Perform detailed Wells & Well Patterns reviews, and identify remedial actions
• Identify external studies scope, RE budget with the close follow-up of the spent vs. plans
• QA/QC the work performed by reservoir engineers within his team (RE-I and below)
• Support the Integrated Reservoir Management team within RMO unit on the cross reservoirs’ activities
• Support FO/PWP for day-to-day and short-term production / injection optimization
• Coach and mentor young nationals in UMO team
• Provide support to RMO, RDG, NWD teams (transverse support)
• Act as Head UMO RMO in his Team Lead’s absence 

• Perform detailed wells performance analysis and postmortem synthesis
• Perform subsurface studies to improve production and injection (slugging, decline analysis, GL ..etc)
• Perform simulation studies (IX) to define optimum injection, short term forecasting, and voidage replacement improvement
• Use of IX and 4D Seismic to identify optimum zonal shifting and injection schemes to increase sweep efficiency
• Segmented well modelling (IX) both in FFM and Single Well Models to optimize and design re-drill wells
• Perform simulation studies to define optimum injection (water), short term forecasting, and voidage replacement improvement
• Lead identifying and prioritizing reservoir surveillance plans, and ensure close follow-up
• Lead opportunities identification, ranking and maturation (Workovers, Stimulation, ..etc) until FID for Deep Redrills, workovers and other opportunities
• Support light workovers maturation (tubing change-out) until final SOR
• Maintain and close follow-up of opportunities hopper 
• Contribute to the generation of the yearly reservoir management plans and ensure their execution
• Consolidate and present the reservoir quarterly Reservoir Management reviews to SH’s
• Perform decline curve analysis and generate the monthly unconstrained profiles for the rolling forecast
• Define completion strategies for re-drill and WO wells supported by simulation studies
• Support the New Well Delivery team all along the WO’s SOR process
• Support the team lead in identifying training needs for team members and recruitment interviews
• Coach and mentor junior team members and Qatari young professionals.
