Development of software for automated digitisation of geophysical survey results of underground gas storage wells

Abstract

The purpose of the work is to store, process and analyse the materials of geophysical surveys of wells (GSW) of underground gas storage (UGS) facilities. In order to reduce the time needed to analyse paper-based GSW data accumulated during the operation of gas storage facilities, it is important to transfer them to electronic form for storage. A set of application software solutions has been developed to achieve the goal.The paper presents approaches to the operational analysis of geophysical information, including its verification, correction and accumulation in digital format. A software package (SP), “Karotazh”, was developed for automated recognition of the results of geophysical surveys of wells, which are important for solving various geological and technological problems by means of prompt processing, systematisation, accumulation of initial information, graphical and documented display of this information. The software for preparation of well logs is designed to enter them into the archive for storage, viewing and further automated recognition (digitisation).In order to solve the tasks set out in the study, it has been used such general scientific methods as systematisation (when selecting the necessary sources of information), generalisation (in the process of defining general terms that highlight the main features), formal logical method, method of systematic analysis of information, descriptive method and modelling method.Implementing the developed software for automated recognition of logging results can increase the efficiency of processing geological and geophysical information on wells and productive horizons to analyse their condition and eliminate complications promptly. Forusers’' convenience, an interface for Ukrainian UGS conditions has been developed, allowing specialists to increase their work’s efficiency. The proposed software solution can be used by oil and gas companies in Ukraine to digitise and provide information support for the analytical processing of geophysical survey results.The approach enables to quickly digitise and analyse well logs and then store them in an electronic archive of geophysical surveys.In order to solve problematic issues in gas storage wells on time, it is necessary to promptly analyse the results of geophysical surveys using modern software tools to predict possible complications and take appropriate measures in a timely manner.Implementation and use of the developed software solution for automated recognition of GSW results at UGS facilities enables to reduce the time for analysis of information in paper form and increase the efficiency of obtaining the necessary information for timely action in case of complications.The authors propose relevant and up-to-date software solutions for the automated processing of GSW results and their storage and use in an electronic archive. Implementing the approach in production enables specialists to quickly analyse information and solve problematic issues.
