Managed and provided technical supports for enhancement of the base production through asset/ reservoir management, new projects, wellbore management (optimizing ESP, SRPs, plunger lift).
•Recommended and ensured the safest and the most cost-effective methods of optimization were utilized, through well surveillance, monitoring well pump performances, and troubleshooting etc.
•Reviewed, assessed and implemented workover, recompletion and well intervention operations during the planning and operational phases at the onshore rig site for numerous wells and implemented management strategies to control cost and enhanced profitability by exceeding the production targets.
•Monitored and manage the well integrity process ensuring the wells are operated within their design limits and facilitating risk assessments.
•Completed more than 90 major minor well works including artificial lift selection, frack solutions, and new technology implementation
•Reviewed, evaluated and executed well stimulation opportunities at the onshore rig site by successfully using acidizing through packer; acidizing using rock salt or ball sealers; PinPoint Injection (PPI), BLUESPARK® technology, StimGun propellant etc. Also, performed and reviewed recompletion task by finding uphole potentials by utilizing hydraulic fracking; acid frack; perf and Gas Gun etc.
•Electrical Submersible pump: - Designed/reviewed ESP sizing based on PROSPER modelling. Experienced with various ESP modifications to achieve maximum run life under various adverse downhole conditions. Operated ESPs under different setting methods to optimize and maximize production without sacrificing well reliability. Also, developed real-time monitoring system
•Performed lookbacks on all well activities for the asset and shared the results with management by explaining the cost-effective solutions to improve production.
Worked hand in hand with Conoco operations team on daily production engineering activities for condensate gas wells including daily reporting, well monitoring, allocation, surveillance and troubleshooting.
•Devised strategies to maximize value over the life of field with appropriate use of IPM modelling. Managed contractors and Conoco engineers during Re-perforation Campaign through candidate selection & optimization.
•Provided technical support to onshore cross functional team and travelled offshore when required to assist the team based in offshore.
•Conducted direct business critical systems reviews and quantified business risks associated with asset such as, optimized shut in and production schedules reducing LPO due to “condensate banking effects” etc.
•Recommended and applied new technology to achieve performance improvement- Focal point for the Velocity String and Capillary String installation campaigns, Foamer chemical skid installation, comingled dual wellhead separation project for backpressure reduction across the pipeline, etc.
•Coached & assisted peer engineers (Chevron/Conoco) in understanding the PROSPER & GAP workflow and then coached how to construct PROSPER models (built all 52 PROSPER models from scratch). Also wrote Britannia Integrated Asset Modeling (IAM) workflow document.
•Mentored offshore PE to implement optimum and achievable production strategies based on the equipment availability, reservoir condition and flare constraint.
Developed detailed completion procedures for Slot recovery, New Well Completion (Sidetrack) and Workovers. Served as liaison between D&C, asset and project Teams to identify reservoir management objectives and develop viable alternatives. Provided rig site quality assurance during execution of stimulation operations and installation of completions hardware. Provided day-to-day support to D&C Superintendent during all phases of completions and trouble shooting. Responsibilities included:
•Composed HSE Notification and optimized fit for purpose completion cost estimates (A.F.E.)
