US Patent Issued to Halliburton Energy Services on Nov. 4 for "Cement bonding evaluation with a sonic-logging-while-drilling tool" (Singaporean Inventor)

ALEXANDRIA, Va., Nov. 6 -- United States Patent no. 12,460,532, issued on Nov. 4, was assigned to Halliburton Energy Services Inc. (Houston).

"Cement bonding evaluation with a sonic-logging-while-drilling tool" was invented by Ruijia Wang (Singapore).

According to the abstract* released by the U.S. Patent & Trademark Office: "Waves from cement bond logging with a sonic logging-while-drilling tool (LWD-CBL) are often contaminated with tool waves and may yield biased CBL amplitudes. The disclosed LWD-CBL wave processing corrects the first echo amplitudes of LWD-CBL before calculating the BI. The LWD-CBL wave processing calculates a tool wave amplitude and a phase angle difference as the difference of the phases between the tool waves and ca...
