Title: Makito Katayama: Innovator in Wellbore Surveying Technologies
Introduction
Makito Katayama is a notable inventor based in Clamart, France. He has made significant contributions to the field of wellbore surveying, holding a total of 5 patents. His innovative approaches have advanced the methods used in drilling and surveying operations.
Latest Patents
One of his latest patents is focused on wellbore surveying using a tilted survey sensor. This method involves rotating a downhole tool equipped with a tilted survey sensor in the wellbore. The tilted survey sensor has a sensory axis that is rotationally offset from the longitudinal axis of the downhole tool. It is utilized to make sensor measurements while the downhole tool is rotated. The sensor measurements are then fitted with a sinusoidal fitting function to derive first and second fitting parameters. These parameters are essential for computing wellbore survey parameters such as wellbore inclination or azimuth.
Another significant patent by Katayama addresses low inclination magnetometer bias compensation for dynamic surveying. This method includes rotating a Bottom Hole Assembly (BHA) in a wellbore while making triaxial accelerometer and magnetometer measurements. These measurements are taken using corresponding triaxial sets deployed in a roll-stabilized housing. The computed magnetic dip angles are compared with a reference magnetic dip angle to select a magnetometer bias that minimizes the difference between the two.
Career Highlights
Makito Katayama is currently employed at Schlumberger Technology Corporation, a leading company in the oilfield services sector. His work focuses on enhancing drilling technologies and improving the accuracy of wellbore surveys.
