U.S. Patent No. 8,701,759 issued encompassing recently announced centralizer innovation

Composite Centralizer

(Fort Worth, TX) –– Summit Casing Equipment, the leader in the innovation of oil and gas field casing equipment, today revealed its groundbreaking TD LoCo Composite Centralizer has been awarded U.S. Patent No. 8,701,759, a utility patent issued by the U.S. Patent & Trademark Office. Summit inventors developed the TD LoCo to have a Low Coefficient of friction, allowing casing to reach total depth with greater speed, efficiency and effectiveness.

Summit’s application to the USPTO explained the TD LoCo’s ultra-durable one-piece design integrated a curved slope blade design as opposed to a step, “in order to avoid creating surfaces that can get caught on discontinuities in the bore hole.” Built for high impact stress and heat resistance to maintain its integrity under extreme wellbore temperatures, its proprietary composite construction “allows (the TD LoCo) to have superior material properties for use within the harsh environment that casing centralizers are exposed to in oil and gas wells.”

“It’s a great day for us,” said Mitchel Hansen, Summit’s Chief Operating Officer and co-inventor. “The USPTO’s decision to issue this patent affirms what the TD LoCo is demonstrating in the field to engineers on drill sites nationwide: it is truly unique in its category.”

The TD LoCo was featured recently by the Midland Reporter-Telegram, the leading news source for one of the nation’s highest producing oil & gas regions, which referenced the “tremendous response” the centralizer has seen from operators in the Permian Basin.

“We pride ourselves on what we call the ‘Summit Standard,’ which is our commitment to provide the highest quality products and service available,’” said Andy Eldridge, Chief Financial Officer and TD LoCo co-inventor. “We’re celebrating, but with each success we challenge ourselves to set the bar higher and investigate new ways to advance the technology.”
