Management of Sustainable Development of the Fuel and Energy Complex of the Regional Economic System Based on Digital Technologies by Ekaterina A. Zemlyacheva

“…To do this, based on statistics for the regions of Russia in 2022, an econometric model for managing the sustainable development of the fuel and energy complex of the regional economic system based on digital technologies is compiled using the method of regression analysis. As a result, it was concluded that digital technologies largely determine the sustainability of the fuel and energy complex in Russian regional economic systems, but flexible use of these technologies is necessary, focusing on those that most and consistently support the sustainable development of the fuel and energy complex in the regions of Russia. …”

Simulation of reasonable shut-in time for shale oil after volume fracturing by LIAO Kai, ZHANG Shicheng, XIE Bobo

“…Based on the law of change in incremental oil volume, a reasonable shut-in time is identified to be between 30 to 45 days. ③ Considering real working conditions, “fracturing & well shut-in time” is proposed as an indicator for optimizing well shut-in, which aims to improve time efficiency and reduce differences between wells. This paper proposes an evaluation method and simulation workflow for assessing the well shut-in effects of volume fractured horizontal wells, offering valuable guidance in optimizing the reasonable shut-in time for shale oil fractured wells.…”
