Mariño-Martínez Ingeniería CBM isotopes isotherms coal bed gas permeability Due to the decrease of natural gas reserves and the high death toll from explosions in coal mines, Colombia has been carrying out preliminary explorations of coalbed methane (CBM). Until now, CBM exploration has focused on the gas content per ton of coal from canister desorption systems, but few additional tests have been done to determine coal gas saturation, gas origin, methane percentage and coalbeds permeability. The purpose of this research is to analyze recent information in the country on the use of adsorption isotherms, C13 and deuterium isotopes analyses, gas chromatography and permeability modeling. Adsorption isothermal test indicates that coalbeds are sub saturated, isotopic results show that gas origin is mainly biogenic, that methane content would be below 77%, and that permeability values could be high. These results also indicate that more isotherms, isotopes, chromatography and permeability tests are required to clarify with greater precision methane saturation, gas origin, methane percentage and flow capacity that CBM deposits would have in Colombia, and in this way ensure that there is enough gas to achieve economic feasibility in future projects. It is also concluded that the exploration has been superficial and that it is necessary to investigate the CBM at depths greater than 500 m, at a prudent distance from mining works and away from highly fractured areas; preferably in structures such as synclines with low deep structures, which should include studies of fractures, diagenesis, and reservoir modeling. 2022 artículo científico 0123-3033 https://www.redalyc.org/articulo.oa?id=291374362004 https://www.redalyc.org/journal/2913/291374362004/ https://www.redalyc.org/journal/2913/291374362004/html/ https://www.redalyc.org/journal/2913/291374362004/291374362004.epub https://www.redalyc.org/journal/2913/291374362004/movil 10.25100/iyc.v24i2.11343 en http://www.redalyc.org/revista.oa?id=2913 Ingeniería y Competitividad application/pdf Universidad del Valle Ingeniería y Competitividad (Colombia) Num.2 Vol.24 |
