Title: Alexander Trushin and His Well-Technology Patents.

Introduction

Alexander Trushin is an inventor based in Perth, Australia, whose patent work focuses on technologies for oil and gas wells. His inventions address gas lifting and sealing applications in wellbores. He is associated with Schlumberger Technology Corporation and holds 2 patents.

Latest Patents

Trushin’s listed patents include “Low-cost downhole gas lift system for non-gas lift tubing” and “High expansion aggregate seal.”

“Low-cost downhole gas lift system for non-gas lift tubing” describes a method for lifting fluid in a well. It uses a gas lift valve installed near an opening in production tubing and a pump positioned above that opening. Gas enters the tubing through the valve, while the pump initially helps lift fluid. Once gas lifting is detected, the pump is stopped and removed.

“High expansion aggregate seal” describes a plugging tool designed to travel through a wellbore or well tubular. Its seal section uses spaced extrusion barriers and a mechanism that moves them toward each other, expanding an elastomer sealing element radially between them.

Career Highlights

The two inventions reflect Trushin’s work on practical downhole equipment, including systems for fluid production and tools for sealing wellbores. His association with Schlumberger Technology Corporation connects his patent activity with the energy technology sector.

Collaborations

Trushin’s listed coworkers include Oliver Fry and Ilja Kivko. Their names provide context for his professional network, though the supplied information does not specify their roles in the patents.

Conclusion

Alexander Trushin’s patents address two distinct well-technology challenges: enabling gas lift in non-gas-lift tubing and creating an expandable seal for downhole plugging.
