Biography

I am a seasoned process and chemical engineer with extensive experience in the upstream oil and gas industry. My expertise encompasses interfacing and integrating across multiple disciplines, including subsurface, subsea, topsides, geotechnical, and commercial. I excel at delivering process and system designs for a wide range of development types, such as deep-water, heavy oil, HP/HT, gas condensate, gas storage, greenfield, and brownfield projects.
I have a proven track record of leading multiple small project and study teams through all stages of field development, from conceptual and pre-FEED to FEED, detailed design, and operations.

Areas of Expertise:
• Steady-State and Transient Multiphase Modeling: Extensive expertise in PIPESIM, GAP/PROSPER, and OLGA.
• Fluid Modeling Software: Proficient in HYSYS, UNISIM, PVTSIM, and Multiflush for fluid characterization studies.
• Subsea Pipeline Operating Procedures: Skilled in developing start-up, cooldown, blowdown, and restart procedures.
• Flow Assurance Studies: Expertise in risk identification, mitigation and remediation planning, slugging analysis, blowdown and depressurization studies, as well as start-up, shutdown, and chemical requirement assessments.
• Sustainability and Renewable Energy: Knowledgeable in hydrogen production, transportation, storage, energy efficiency, sustainability, renewable energy, and carbon capture and utilization.
My approach ensures seamless project execution and optimized field development outcomes.
