Title: The Innovative Contributions of Vivian Pistre
Introduction
Vivian Pistre is a prominent inventor based in Tokyo, Japan. She has made significant contributions to the field of quantitative cement evaluation and acoustic measurements. With a total of 7 patents to her name, her work has advanced the methodologies used in wellbore operations.
Latest Patents
One of her latest patents is titled "Determining a quantitative bond using signal attenuation." This technique facilitates the determination of a quantitative bond between a pipe and adjacent materials, such as the bond between a wellbore casing and adjacent cement. The quantitative bond is established through acoustic measurements related to signal attenuation. Additionally, these measurements can be conducted with a sonic tool during wellbore operations, such as drilling. This methodology enables the use of signal attenuation to determine bond index coverage up to a high percentage, potentially reaching 100 percent.
Another notable patent is the "Method and system of quantitative cement evaluation using logging while drilling." This method involves deploying a logging-while-drilling downhole sonic tool into a wellbore inside a casing. It measures acoustic signals propagating through the casing and performs quantitative cement evaluation regarding cement bonding around the casing by utilizing waveform data from the measured acoustic signals.
