The meticulous methodology of the technique identified and corrected an error in production cycle times, recognizing irregular elements that had been ignored in previous measurements, as well as strange elements produced during drilling activities, which set pace to the entire process. Finally, an improved and adapted technique was developed for this sector, through which process cycles could be determined at a 7.3% error, an acceptable value due to access limitations to the extraction areas by the strict security measures and reduced bias in planning production projections. 2021 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49671325019 https://www.redalyc.org/journal/496/49671325019/ https://www.redalyc.org/journal/496/49671325019/html/ https://www.redalyc.org/journal/496/49671325019/49671325019.epub https://www.redalyc.org/journal/496/49671325019/movil 10.7440/res64.2018.03 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.218 Vol.88 |
