Zeljko Jericevic is a notable inventor based in Houston, TX (US), recognized for his contributions to well logging technology. He holds a total of 9 patents, showcasing his innovative approach to solving complex problems in the field.

Latest Patents

Among his latest patents is a method for correcting well log data for the effects of changes in instrument velocity, specifically addressing the cable yo-yo phenomenon. This method involves preprocessing data to reduce the magnitude of spatial frequency components that occur within a specific bandwidth related to the axial acceleration of the logging instrument. The process includes shifting eigenvalues of a matrix over depth intervals where the smallest absolute value of one of the eigenvalues changes sign. This technique ensures that the smallest absolute value eigenvalue does not change sign, thereby enhancing the accuracy of measurements converted to values of properties of interest in earth formations. The method also incorporates low pass filtering and phase shifting to further refine the data.
