“…These computational algorithms were applied to model and simulate the complexity of unconventional reservoirs. ANN was explored in choosing the best location for injection in gasassisted gravity drainage for reaching the optimized pressure and production rate in a fractured carbonate reservoir [230]. The result showed high efficiency and ANN as a powerful tool for optimizing the location of the injection.…”

The market volatility in the oil and gas (O&G) sector, the dwindling demand for oil due to the impact of COVID-19, and the push for alternative greener energy are driving the need for innovation and digitization in the O&G industry. This has attracted research interest from academia and the industry in the application of industry 4.0 (I4.0) technologies in the O&G sector. The application of some of these I4.0 technologies has been presented in the literature, but the domain still lacks a comprehensive survey of the application of I4.0 in the O&G upstream sector. This paper investigates the state-of-the-art efforts directed toward I4.0 technologies in the O&G upstream sector. To achieve this, first, an overview of the I4.0 is discussed followed by a systematic literature review from an integrative perspective for publications between 2012-2021 with 223 analyzed documents. The benefits and challenges of the adoption of I4.0 have been identified. Moreover, the paper adds value by proposing a framework for the implementation of I4.0 in the O&G upstream sector. Finally, future directions and research opportunities such as framework, edge computing, quantum computing, communication technologies, standardization, and innovative areas related to the implementation of I4.0 in the upstream sector are presented. The findings from this review show that I4.0 technologies are currently being explored and deployed for various aspects of the upstream sector. However, some of the I4.0 technologies like additive manufacturing and virtual reality are least explored.INDEX TERMS Artificial intelligence (AI), cyber-physical systems, digital-twin, framework, oil and gas (O&G), industry revolution 4.0 (IR 4.0), industry 4.0 (I4.0), internet of things (IoT), simulation, upstream sector

“…With the in-depth studies on the efficient and low-cost drainage gas recovery processes, more and more technologies are being used in process optimization and transformation [2] . Multi-disciplinary gas pool water control technology that combines single well drainage technology and gas pool engineering is considered as a typical [3] , and a variety of advanced drainage gas recovery programs area also formed [4] . In China, the study on gas recovery technology started from 1978, after decades of research, a variety of supporting gas recovery processes have been developed, such as bubble row, concentrated pressurization and so on [5] .…”

“…In views of the wellhead pressure and production distribution in western Sichuan gas field, gas wells with the wellhead oil pressure of less than 1MPa account for 30%; gas wells with the wellhead oil pressure between 1.0-2.0MPa account for 39.4%; gas wells with wellhead oil pressure between 2.0-2.5MPa account for 8.6 %. There are a total of 288 gas wells that have the daily gas production of less than 0.5 ×104m 3 , and have the annual output of 2.1971 ×108m 3 , accounting for 19.64% of total annual output. In addition, there are a total of 250 gas wells that have the output of less than 0.5×104m 3 , the wellhead pressure of less than 2.5MPa, and the annual production output of 1.8×108m 3 , accounting for 16.1% of total annual output.…”

Abstract. In this paper, the data about drainage gas recovery in 11 middle-shallow layer of gas fields in western Sichuan gas field are studied, and the alternative drainage gas recovery program is selected. According to the geological characteristics, the water production mechanism of gas reservoirs and the water production characteristics of water-yielding gas well, the technological economic integrated evaluation indicators of the middle-shallow layer reservoirs in western Sichuan are established. By establishing the optimization model of DEA drainage gas recovery program, the technological program is analyzed, and the economic benefit is accurately evaluated, so as to select the optimal drainage gas recovery program.
