Algorithm for selecting a development strategy for gas and gas condensate fields with integration of gas processing facilities at the conceptual design stage

Developing a field development strategy is a crucial part of a reservoir’s lifecycle. Key principles of this strategy established during the conceptual design stage. Decisions made during this early phase lay the groundwork for the overall success and economic efficiency of the project. However, this stage is characterized by a high level of uncertainty.Currently, the new gas production region in Russia — Eastern Siberia — is experiencing active development. This region lacks developed infrastructure and does not have the same resource base as Western Siberia. Additionally, much of the gas potential in Eastern Siberia remains at the selecting, exploration and evaluation stages.However, many fields in Eastern Siberia are rich in valuable gas components. Given that the current industry trends towards product diversification and improved monetization, there is an increasing need to formulate development strategies at the conceptual stage.These strategies are based on not only field clustering but also creating of new gas processing facilities, especially in remote areas that are far from existing gas transportation systems.This paper presents an algorithm for comprehensive input data analysis using the example of the Eastern Siberian cluster, which consists of a group of fields in Krasnoyarsk Krai. This algorithm facilitates the forecasting and comparative assessment of various development options, ranks them according to potential efficiency, and determines the necessary equipment configuration for implementing the selected field development strategies.
