Certified Process Design Engineer with 17+ years of experience in process engineering in the upstream oil & gas industry, working on conceptual design, FEED and detailed design stages for greenfield and brownfield projects. Provided effective infrastructure solutions from Conceptual design to Detailed design. Being a part of cross-functional team determined potential value and viability of prospective Green fields. Integrated medium- and long-term reservoir exploration plans with facilities development strategy. Analyzed and checked Brown field technological processes identifying opportunities to optimize utilization or de-bottlenecking, reducing costs and increasing efficiency. Leveraged the results of scientific research, including my own, to enhance the effectivity. Developed a number Operations Philosophies for newly designed and existing oil and gas treatment facilities and prioritized operational and environmental safety. - Process ideas generation / matrix of scenarious- Simulation Study and Process Optimization- PFDs / H&MB/ BFDs / UFDs- Unit / Equipment List- Equipment Sizing (Vessel, Tank)- Pump and Compressor Calculations- Air Cooler, Shell & Tube Heat Exchanger Thermal Design- Pipeline Sizing- Flow assurance- Flare Calculations- CAPEX, OPEX Estimation and planning- Master plan- MOCKEY ACHIEVEMENTS:- Enhanced net present value (NPV) of an oil asset by over $27 million through the conceptual design of infrastructure solutions (gathering and export pipelines, treatment facilities) for an explored unconventional gas condensate deposit.- Conducted in-depth analyses of 4 prospective oil and gas license areas, identifying significant potential in 3, with estimated NPV between $10 million and $80 million each. Determined that the 4th area would be unprofitable, resulting in a cost savings of $0.9 million.- Developed a comprehensive petroleum gas utilization strategy that increased hydrocarbons monetization and reduced the penalties paid to $2.0 million annually.- Created digital twins for 3 Gas Condensate Processing Plants using HYSYS. Analyzed current and future bottlenecks, offered the most efficient solutions. Evaluated the feasibility of transitioning to various products by assessing equipment capacity and performance characteristics, incl. velocities and performance maps.- Estimated and integrated the coalescer efficiency ratio into the design of an advanced heater-treater, leading to cost reduction of $0.8 million (15%) for 2 facilities.
