Application of the software "ZHULDYZ". Adaptation and work with models

Abstract

Background: One of the conditions for the effective development of oil and gas fields is reliable forecasting of its exploitation, including using the capabilities of modern software. As a result of many years of work, the first and only Kazakhstani import-substituting software product "Zhuldyz" was developed which helps to control the implementation of process solutions at the field.
 Aim: Implement a single software platform covering the complete cycle of exploration and development of the fields.
 Materials and methods: This paper presents the experience of using the Zhuldyz software at the Karatobe Yuzhnoye field, as well as software modules for optimizing modeling processes.
 Results: Using software accounting a set of geological and physical results and the production history of the Karatobe Yuzhnoye deposit, data were obtained for constructing development maps, assessing reservoir connectivity and distribution of injected water, analyzing field performance for wells, selecting candidate wells for well interventions, as well as software modules for optimizing modeling processes. Additional opportunities for assessing and comparing field development indicators have also been identified.
 Conclusion: Based on the results of the analysis carried out in the Zhuldyz software, solutions were developed to improve the reservoir pressure maintenance system at the Karatobe Yuzhnoye deposit. The selection of wells for well interventions and the calculation of efficiency were carried out, which will reduce the number of unsuccessful well interventions by increasing the quality of selected candidate wells through a new appraisal approach from a geological and technological point of view.
