Análisis de trabajos críticos de estimulación realizados en las campañas 2015-2017 en el Campo Yaguará, mediante simulación numérica

The need to improve the productivity of the wells in the Yaguará field, leads the operator, in this case ECOPETROL SA, to implement different treatments in the 2015-2017 campaign that improve the production of oil in several wells in the field, implementing appropriate operating processes to the enterprise. To execute these treatments, it was necessary to understand basic concepts about matrix stimulation and hydraulic fracturing. In addition to knowing the reason for its implementation, that is, why it was vital to make use of these in the Yaguará Field. The main reason for carrying out these works was the existence of formation damage present in wells Z and C. Due to the above, it was necessary to gather information from the Yaguará Field, its petrophysical characteristics, production history and stimulations in previous years, with the purpose of executing an analysis that would allow to identify if the stimulations implemented in the wells had the expected effect or, for on the contrary, unfavorable results were obtained in the increase of crude production. The respective analysis was made through nodal analysis in PROSPER software, productivity simulation models, and operational well reports. This allows us to identify the effectiveness of the treatments, compare expected versus obtained results, recognize the damage factor before and after the stimulation and, of course, quantify the productivity of the well after implementing the stimulations.
