“…The Yangtze platform is one of the three oldest in China and is divided into three tectonic units: the Upper, Middle, and Lower Yangtze regions [47] (see Figure 1). The Upper Yangtze Platform is bounded by the Qinling-Dabie orogenic belt to the north, the Red River Fault Zone to the southwest, the Xianshuihe Fault Zone to the west, and the Cathaysia Platform to the southeast [48]. The Middle Yangtze area is located in the middle reaches of the Yangtze River, bounded by the Baojing-Cili fault in the southeast and separated from the Jiangnan-Xuefeng paleo-uplift, with the Qiyueshan fault in the northwest being separated from the rest of the structure in eastern Sichuan.…”

This study comparatively analyzed the geological, geochemical, reservoir, and gas-bearing characteristics of the lower Cambrian marine shale in the Middle and Lower Yangtze regions. The main factors controlling the gas-bearing properties of the shales were identified, and the favorable and unfavorable conditions for shale gas accumulation are discussed. The results show that the organic carbon contents and thermal evolution degree of the organic matter in the lower Cambrian marine shale in the Lower Yangtze area were higher than those generally found in the Middle Yangtze area. The brittle mineral composition of the Middle Yangtze area was typically low silicon and high calcium, whereas the Lower Yangtze area was characterized by high silicon and low calcium. The development of micropores in the Lower Yangtze area was poorer than in the Middle Yangtze area, with the organic pores being particularly underdeveloped. The adsorption capacity of shale in the Lower Yangtze area was obviously higher than in the Middle Yangtze area. It was considered that the organic carbon content, thermal evolution degree, and molecular structure of kerogen were the main factors that controlled the adsorption properties of the shale. In addition, the Lower Yangtze area suffered a stronger tectonic transformation and frequent magmatic activity, and the preservation conditions were inferior to those in the Middle Yangtze area.

“…Among others, GMDH has been utilized for accurate log interval value estimation (Mohammed Ayoub (2014) [34]), permeability prediction by Alvin K. Mulashani (2019) [35] and Lidong Zhao (2023) [36], as well as permeability modeling and pore pressure analysis by Mathew Nkurlu (2020) [37]. Additionally, GMDH finds applications in cement compressive strength design (Edwin E. Nyakilla, 2023 [38]), rock deformation prediction (Li et al, 2020 [39]), bubble point pressure estimation by Fahd Saeed Alakbari (2022) and Mohammad Ayoub (2022) [40,41], gas viscosity determination, CO 2 emission modeling (Rezaei et al, 2020 and2018 [42,43]), the prediction of CO 2 adsorption by Zhou L. (2019) [44] and Li (2017) [45], forecasting stock indices, and modeling power and torque as demonstrated by Ahmadi (2015) [46] and Gao Guozhong (2023) [47], and the prediction of pore pressure by Mgimba (2023) [48].…”

This paper presents data-driven modeling and a results analysis. Group method data handling (GMDH), multivariable regression (MVR), artificial neuron network (ANN), and new proposed GMDH-featured ANN machine learning algorithms were implemented to model a field telemetry equivalent mud circulating density (ECD) dataset based on surface and subsurface drilling parameters. Unlike the standard GMDH-ANN model, the proposed GMDH-featured ANN utilizes a fully connected network. Based on the considered eighteen experimental modeling designs, all the GMDH regression results showed higher R-squared and minimum mean-square error values than the multivariable regression results. In addition, out of the considered eight experimental designs, the GMDH-ANN model predicts about 37.5% of the experiments correctly, while both algorithms have shown similar results for the remaining experiments. However, further testing with diverse datasets is necessary for better evaluation.

“…Recently, there has been an increasing global energy demand due to the rise in population and growing prosperity. − Numerous studies urged that over 80% of energy in the world is produced from fossil fuels such as natural gas, petroleum, and coal, with 96% of carbon emitted into the atmosphere after combustion. Minimizing the utilization of fossil fuels or using less carbon emission fuel will reduce greenhouse gases (GHGs) in the atmosphere .…”

Many researchers have investigated the potential of methane hydrate reservoirs (MHRs) for carbon dioxide (CO2) sequestration and methane (CH4) production through the CO2–CH4 replacement method. This technique is not yet commercially implemented due to various limitations, especially economic reasons. This study investigated recent advancements in MHRs potentiality for CO2 sequestration through CO2 or mixed gas exchange injection while recovering CH4. From the experiments, modeling, and simulations, and one pilot test conducted, it was found that there is a great potentiality of sequestrating CO2 in MHRs while recovering CH4. In addition, it was revealed that to produce more CH4, the nitrogen/hydrogen (N2/H2) mole fraction in the injector gas stream should be more significant than that in CO2, while to sequestrate more CO2, the CO2 mole fraction in the injector gas stream should be greater than the N2/H2 mole fraction. The CO2–mixture gases mole fraction ratio recommended from one successful pilot test conducted was 23:77 (CO2/N2), which revealed that approximately 60% of injected CO2 was sequestrated with 855 × 103 standard cubic feet of CH4 produced. The challenges identified in this review will urge researchers to explore suitable technologies to conduct more pilot tests and pave the way toward entire field operations on CO2 sequestration in MHRs toward decarbonization.
