Analysis of the existing and development of new software packages for processing and interpreting of geophysical well logging data
Abstract
At present there exists many packages for interpreting geophysical well logging data, permitting to solve geological tasks and monitor well technical condition. For well condition status evaluation a complex of geophysical methods is used, including acoustic, radioactive, electromagnetic and other methods. This article makes a comparative analysis of possibilities of the existing well logging software packages for monitoring well technical condition. In the course of the studies we have in details analyzed both packages by other developers and own modular system for processing and interpreting geophysical well logging data («SONATA»), reviewing possibilities of the programs at all stages of data processing and interpreting: various data formats support, material quality evaluation according to industry standards, step-by-step processing support, preprocessing, signal parameters determination, calculation of physical mechanical properties and other parameters, processing data of various acoustic, radioactive, electromagnetic methods and profile logging. Advantages of «SONATA» system in comparison to the existing program complexes are demonstrated. Internal arrangement of «SONATA» system and utility software packages accompanying the program package is analyzed in details. Major peculiarities of «SONATA» system software architecture are presented: object and component models reflecting internal arrangement of interpreting complex. From the companion programs in details are analyzed geophysical well logging data compression packages, their evolution and algorithms developed for compression. Many years of experience of using geophysical well logging data processing and interpreting modular system «SONATA» by geophysical organizations in Russia and former USSR have demonstrated that the software complex is in demand with oilfield servicing organizations, permitting them to solve the complete range of tasks on monitoring well technical conditions, providing ergonomic interface and convenient set of tools for generation of resulting conclusions and documents.
