Abstract: Previo a la aparición de los simuladores hasta la actualidad, la comunidad petrolera ha manejados términos que se han vuelto tan familiares que simplemente no se han estudiado al detalle y se han asignado características tácitas, sin haberse comprobado previamente. Una de estas características intrínsecas asignadas al término “buen empaquetamiento”, supone la conexión con una fractura de elevada conductividad, mientras se logre una tendencia de incremento en el comportamiento de presión, en las últimas etapas del fracturamiento y de esta manera se logra una fractura conductiva y bien conectada con el pozo, situación que no es necesariamente cierta.
La aplicación de las técnicas: Tip screen out “TSO” (control del crecimiento longitudinal de la fractura), frac pack (empaquetamiento de la fractura con grava) entre otros, para lograr buenos empaques, se emplearon en varios campos petroleros indiscriminadamente para formaciones de baja, mediana y altas permeabilidades, sin embargo, las fracturas con excelente empaquetamiento final, no lograban producir los caudales estimados para las formaciones donde fueron colocadas. Con el fin de lograr el ajuste de producción obtenida en función de longitud de fractura, se utilizó valores de longitud muy por debajo a los reportados por los simuladores de fracturamiento.
Al estudiar los tratamientos ejecutados, entendemos que se lograría un comportamiento productivo esperado dependiendo de cómo se bombee, se transporte y se coloque el propante en la fractura. El transporte y colocación del agente sostén, genera comportamientos de presión identificables durante el tratamiento y en ningún caso queda establecido que una elevada tendencia de incremento de la presión, sea beneficioso en la generación de longitud efectiva de la fractura.
Prior to the appearance of simulators to the present day, the oil community has handled terms that have become so familiar that they simply have not been studied in detail and tacit characteristics have been assigned without having previously verified. One of these intrinsic characteristics assigned to the term “good packing”, supposes the connection with a fracture of high conductivity while a tendency of increase in the pressure behavior is achieved in the last stages of the fracturing and in this way a conductive fracture and well connected to the well, a situation that is not necessarily true. The application of the techniques: Tip screen out "TSO" (control of the longitudinal growth of the fracture), frac pack (packing of the fracture with gravel) among others, to achieve good packing were used in several oil fields indiscriminately for low formations, medium and high permeabilities, however, the fractures with excellent final packing, failed to produce the estimated flow rates for the formations where they were placed. In order to achieve the production adjustment obtained as a function of fracture length, length values far below those reported by the fracturing simulators were used. When studying the treatments carried out, we understand that an expected productive behavior would be achieved depending on how the propant is pumped, transported and placed in the fracture. The transport and placement of the support agent generates identifiable pressure behaviors during treatment and in no case is it established that a high tendency to increase the pressure is beneficial in the generation of the fracture effective length.
