“…Tracer testing has also been proven to help in unconventional reservoirs. The unconventional reservoirs are subjected to multiple fracturing and EOR techniques (Joshi et al 2022); tracers can also be utilized to study the effect of production while fracturing and EOR process are underway (Wu et al 2022). Therefore, providing a real-time data analysis of the process helps in optimizing the same.…”

The significance of the tracer testing technique is widely accepted in reservoir performance analysis in hydrology as well as in hydrocarbon exploration and production. The subsurface reservoir delineation for hydrocarbon exploration and optimum production is one of the most critical aspects of petroleum system analysis. The quality of the reservoir and its performance prediction require extensive knowledge of qualitative reservoir geology, its depositional environment, facies heterogeneity and engineering properties of subsurface formations. Tracer testing is amongst the few techniques available in the oil and gas (O&G) industry, which stands up to these expectations and is successfully used for quantitative determination and analysis of sub-seismic scale structural and stratigraphic heterogeneities. Tracer testing is also being utilized in determining residual oil saturation (Sor) and lateral correlation of reservoir properties in the subsurface. Apart from the O&G industry, the concentration-based applications of tracer testing have been proved in hydrology, geothermal and medical science. A comprehensive review is presented to explain the application of tracer testing technique to investigate porous media, mainly in O&G industry. The type of tracers used, their selection criteria, concentration, and natural versus gradient and qualitative to a quantitative application are discussed in the current review. Generally, two types of tracers (chemical and radioactive) are preferred in the petroleum industry for gas/fluid flow assessment, waterflood optimization and establishing connectivity between multiple wells. The current paper reviews both types of tracer tests, namely single well and inter well, in detail discussing the objectives, calculations, designing, injection, sampling, laboratory analysis and knowledge integration. The preliminary aim was to provide a review of the tracer testing technique used in reservoir evaluation and well-to-well connectivity analysis.

“…Coal mine gas (coalbed methane) is a high-quality clean source of energy and a good industrial, chemical, power generation and residential fuel (Wang, Fan et al 2019, Zhou, Hu et al 2020, Zhao, Zhuo et al 2021, Buzek, Cejkova et al 2022, Jha, Ghosh et al 2022. Besides, coalbed methane drainage is quite important for the safe production in coal mines and the utilization of gas resources (Zhou, Xia et al 2016, Banik 2020, Zhou, Hu et al 2020, Ponnudurai, Kumar et al 2022, Joshi, Prajapati et al 2023, Kishor, Kumar Srivastava et al 2023, Ye, Li et al 2023.…”

The coalbed methane drainage with surface well, under the mining effects in a high gas coal mine has become increasingly important, especially for a complex region for the coalbed methane drainage. In contrast, due to the effects of coal mining, the surface wells are prone to deformation and damage. In this paper, a displacement and deformation model for the overlying strata was established. Three forms of deformation and failure of the surface well casing were proposed, such as shearing, stretching and uneven extrusion. Moreover, the mathematical model functions of “S” - type shear deformation, delamination tensile deformation and non-uniform extrusion for the surface well were established. In the ShanXi Coal Group YueCheng Mine, on the mining affected area surface well the coalbed methane drainage practice was conducted, producing a good coalbed methane drainage effect. YCCD-04 well without local protective device was deformed and damaged, and the dynamic deformation and failure process of surface well was detected by well imager; YCCD-02 well with local protective device has experienced mining and gas drainage effect is good, which verifies the effectiveness of local protective device. The YCCD-02 well coalbed methane drainage was 35 months in duration and the cumulative extraction of coalbed methane drainage volume was 1.3×107 m3. Simultaneously, the problem of gas control in the working face was solved, to ensure the safety of coal mining, achieving good social and economic effects.

“…The global energy crisis and the worsening greenhouse effect have made the exploitation of coalbed methane (CBM) a pressing need in countries such as Australia, China, and the United States. − The development of CBM in China is mainly focused on underground extraction. The limited data regarding CBM extraction indicate that the output from underground CBM extraction is over 3 times that of surface CBM extraction in China.…”

The multibranched borehole drilling (MBBD) method employs a self-propelled nozzle (SPN) to artificially create multiple branching boreholes (BBs), which induces fracturing of the coal seams and increases their permeability in order to strengthen the extraction of coal seam gas in underground mines. This novel technology for enhancing coal seam permeability has gradually been applied in China, and there have been promising results. To improve our understanding of the drilling-induced fracture distribution patterns of coal seams in underground mines that are created by using MBBD, we employed a numerical model based on the discrete element method (DEM) that uses the Particle Flow Code (PFC) software. We concluded that, while the stress difference has a minimal effect on the fracture area and fracture amount, it significantly impacts the fracture density and subsequent fracture generation efficiency. It was also found that different drilling sequences and branch borehole lengths (BBLs) result in distinct fracture distribution patterns. Additionally, commencing BB drilling along the minimum principal stress direction yields a higher concentration of fractures, whereas initiating BB drilling to the maximum principal stress direction results in a relatively lower cumulative fracture count with a more uniform distribution pattern of the fractures. This study provides numerical insight for the in situ implementation of MBBD.
