... utilises a workflow to accurately quantify reservoir production over time, such that the optimal FBHP is achieved. In early 2021, the first coal seam gas well with HDCNG gas lift technology was installed and put on production in the Surat Basin. The well was previously shut-in for an extended period due...

... includes PCA analysis for reducing the dimension of relevant geological and engineering factors and the RBFN model for nonlinear regression and prediction of the AOFP based on collected field data. The proposed method was applied to the Weiyuan reservoir in the southwest district of the Sichuan basin...

... Abstract This paper explores unlocking major reserves from S1 and H8 reservoirs, which comprise unconventional gas reservoirs forming a network of barely tapped, complex meandering channels spread over 1,500 km 2 . These zones contain nearly half of the initial gas in place volume in Block...

... Abstract Multiphase flow is commonly exhibited for wells producing from low-permeability liquid-rich gas or oil reservoirs. In such cases, rate-transient analysis (RTA) methods that account for multiphase flow may be applied to derive critical hydraulic fracture, reservoir and fluid-in-place...

... Abstract Reservoir characterization and effective exploitation of low permeability reservoirs have always been cutting-edge topics in the world. Carbonate reservoirs in the Middle East are mainly porous carbonate reservoirs with low permeability, which are very different from fractured-cavity...

... into deep learning is proposed to forecast production in tight reservoirs. In the purely data driven approach, model training is driven solely by a data-based cost function which reflects the differences between model predictions and observations. In the proposed approach, a physics-based cost function...

... be supplied. The anticipated outcome is that the interaction will lead to a better understanding of the reservoir(s) and consequently improved forecasting of petroleum rates and recoveries. Results of the study indicate that engineering deals properly with three essential elements of TPS: reservoir, seal...

.... The process utilizes a cyclic injection approach with produced fluids at lower rates and pressures to enhance conductivity of the O-SRV. The extensive development of O-SRV is critical for effective, prolonged reservoir stimulation, leading to more sustained production rates and increased Estimated Ultimate...

... Abstract Underground natural gas storage is a cyclical technique that consists in the use of geological structures, such as depleted oil and gas reservoirs, aquifers, and salt domes, to store gas for future consumption as per demand. Although, underground gas storage has proved technical...

... at the matrix-fracture interface in the reservoir, which could impact the oil recovery factor eventually. Therefore, adding surfactants is believed to improve oil recovery during fracture treatment by reducing the oil-water Inter-Facial Tension (IFT) and altering the matrix-fracture interface wettability...

... Abstract Hydraulic fractures can enhance well productivity from stress sensitive naturally fractured reservoirs such as coalbed methane or coal seam gas (CSG) reservoirs. Graded proppant injection (GPI) has been proposed to enhance long-term, far-field interconnectivity between the created...

... horizontal wells are drilled every year in the YX Shale Gas Field. The difference in logging responses between vertical and horizontal wells brings great uncertainty to reservoir evaluation. This study is based on triple-combo logs, elements, dipole acoustic waves, electrical imaging, nuclear magnetic...

...) is an important method for rapid production performance prediction [1] and is widely used in the production process of oil and gas reservoirs [2 6]. It describes the first process of production (oil and gas flowing from reservoir to bottom hole) and is represented by the relationship between production rate...

... Abstract For the unconventional reservoir, triple-porosity models are widely applied to take the macro-fracture, micro-fracture and matrix system into consideration. However, the models are usually built based on the assumption of sequential flow from matrix to micro-fracture to macro-fracture...
