About Us — Plunger Dynamics

Mission

“To help clients achieve their production objectives by providing multiphase flow and plunger hydrodynamics subject matter expertise, research-backed software solutions, and real-time data-logging projects. We work together to fulfill production optimization opportunities and reduce LOE for operators.”

Our vision is to expand the plunger lift knowledge with industry-wide access to state-of-art research and data analytics. Realizing the full potential of plunger lift is crucial for operators to deploy plungers and optimize runs for 200,000+ suitable wells.

Team

Ozan Sayman

Ozan is co-founder of Plunger Dynamics and leads the development of software solutions, data-logging plunger, experimental and field plunger lift studies for operators. Ozan has conducted PAGL research programs, consulting projects and developed mechanistic models for plunger lift which includes fall and upstroke mechanics of the plunger, and liquid unloading process. He has published journal papers and made presentations at various conferences and workshops, about plunger lift and plunger assisted gas lift.

Ozan is serving as a section officer of SPE Artificial Lift and Gas Well Deliquification Technical Section. Previously, he worked as an engineering consultant for a contractor of the ARPA-E (US Department of Energy) project, and Chevron’s R&D project of acoustic downhole liquid deliquification tool.

Ozan holds a BSc degree in Mechanical Engineering at Istanbul Technical University (2016) and an MSc degree in Petroleum Engineering at the University of Tulsa (2019).

Anvar Akhiiartdinov

Dr. Akhiiartdinov serves as a board member of Plunger Dynamics and he leads the cloud integration, oil field digitalization, and transient modeling. Anvar has extensive research experience on conventional plunger lift to model plunger upstroke with the consideration of liquid fall back, and gas slippage with transient multiphase flow simulation. He has published his findings on smart plunger and data analytics applications for conventional plunger lift.

Anvar holds a BSc degree in Pipeline Engineering and an MS degree in Process Engineering from the Norwegian University of Science and Technology and a Ph.D. degree from the University of Tulsa.

Michael Haci

Michael is an engineer with Plunger Dynamics and brings his experience in reservoir calculations, data analytics, and software solutions.
