Summary: This paper introduces analytical models for pressure distribution in hydraulically fractured reservoirs depleted by horizontal wells with cyclic CO2 injection, aiming to eliminate uncertainties and develop accurate tools for CO2 injection projects. The unique models, derived without approximate methods, consider multiphase flow and can be applied for injection purposes. The study validates the novel flow regime models and emphasizes the importance of understanding CO2 injection timing and hydraulic fracture characteristics in optimizing tight formation CO2 injection processes.

Summary: With the increasing global energy demand, a sustainable and environmentally friendly methane extraction technique is necessary. This study investigates the CH4 recovery process via CO2 injection into different types of kerogens and reveals that the kinetics of adsorption/desorption are faster in immature kerogen compared to overmature kerogen. Additionally, overmature kerogen contains inaccessible micropores which hinder full recovery of CH4. Overall, CO2 injection can achieve high CH4 recovery in different types of kerogens.

Summary: Water scarcity is a major global challenge that poses various engineering and economic issues. Petrolium industries have encountered serious issues requiring pretreatment facilities to reinject produced water. This study aimed to calculate treated water, required water, and water savings for CEOR methods, HF, and other service facilities, finding that HF requires 18% of total water volume and CEOR methods require 28%. Oil-well#3 had the highest daily water savings, with Sirri oilfield having a total annual water requirement of 4131 MM m(3)/Day.

Summary: This research addresses the problem of ranking restaurant locations in the cosmopolitan city of Kolkata, India. It considers various factors and sub-factors to select and rank restaurants in the city. Hexagonal fuzzy numbers are used to deal with the uncertainty, and analytic hierarchy process (AHP) is employed as a multi-criteria decision-making tool. The TOPSIS and COPRAS methods resulted in better ranking compared to other fuzzy numbers, and the sensitivity analysis provides guidance for decision-making in different scenarios.

Summary: This paper explores the application of hexagonal fuzzy multiple-criteria decision-making (MCDM) methodology for the site selection of electric vehicle charging stations. By integrating GIS with MCDM techniques, fuzzy analytic hierarchy process (FAHP) is used to obtain fuzzy weights, while fuzzy technique for order of preference by similarity to ideal solution (FTOPSIS) and fuzzy complex proportional assessment (FCOPRAS) are utilized for ranking selected sites. The study also introduces a centroid-based defuzzification method and a measure for distance between two hexagonal fuzzy numbers (HFN) for this purpose.

Summary: The authors used meter-scale oil shale as the experimental object to study the in situ heating technology for mining oil shale through steam injection. The results showed that hydraulic fracturing started at a pressure 0.34 times lower than the in situ stress, while high-temperature steam fracturing required a pressure 1.2 times higher than the in situ stress. The study also found that horizontal cracks were more easily formed in layered rock masses and that the thermal stress had a stronger influence on the fracture-inducing stress of the orebody.
