Title: **Inventor Spotlight: Steven R. Erbstoesser**

Introduction

Steven R. Erbstoesser is an accomplished inventor based in Missouri City, Texas, known for his innovative contributions to the oil and gas industry. Throughout his career, he has been awarded 14 patents, focusing on advancements in wellbore technology that enhance efficiency and functionality. His work primarily centers around the development of methods for sealing casing perforations, a critical aspect of production in petroleum engineering.

Latest Patents

Among Steven's latest patents is a method for placing ball sealers onto casing perforations in deviated wellbores. This invention introduces a unique technique where multiple ball sealers are delivered into the casing and effectively transported to the perforations using an interface between two immiscible fluids. The first fluid, being denser than the ball sealers, acts as a leading fluid to guide their movement, while the second, trailing fluid also has a density greater than that of the ball sealers.

Another significant patent involves the use of degradable ball sealers to seal casing perforations in a well. This innovation employs ball sealers made from a polyester polymer that remains mostly insoluble in wellbore fluid but degrades when exposed to water at high temperatures. This degradation occurs to create small, soluble molecules, allowing for a return to the original flow through the perforation after the sealing process.
