Hollowlite made a keynote speech at the Cementing Technology Seminar of The China Petroleum Institute

On November 5, 2020, the 2020 cementing Technology Seminar of cementing Group of China Petroleum Institute was held in the ancient city of Xi 'an. As a member unit, Mr. Zeng Rongping, chief engineer of Hollowlite, was invited to give a speech on "the application of high-performance hollow glass sphere in low-density cementing slurry" at the conference.

At the conference, Mr. Zeng mainly introduced the special cementing models of Hollowlite's HL42 and HL35 for oil and gas fields, among which HL42 has been widely used in Southeast Asia and the Middle East. The cementing slurry with the density of 1.55g/cm3 is prepared by HL35 with 1/3 of the conventional amount of cenosphere. It is an ideal substitute for Cenosphere and has been widely promoted in three major oil service companies in the world.

With advanced production technology, excellent product performance and high cost performance, the hollow glass sphere of Hollowlite has been highly approved by many cementing personnel, including Sinopec, Petrochina, CNOOC, China University of Petroleum, Southwest Petroleum University, Tianjin University, Nanjing University of Technology and so on.
