Due to the petrophysical characteristics of Coyotes field, it's necessary to fracture the sandstone reservoir to increase permeability to achieve commercial oil production. There are different technologies based on indirect measurements at the surface or at reservoir level that provide information about the fracture geometry generated in the well while the fracture is created, but all those techniques provide only partial information about the fracture geometry because they are limited by the depth of investigation. For this reason, PEMEX's technical team looked for new technologies for obtaining more precise information about the geometry of the fractures. The company selected a technology that offered monitoring and interpretation of microseismic events generated while the fracture propagated in the reservoir. This study documents the hydraulic fracture monitoring (HFM) of a group of wells located in Coyotes field and discusses the creation of 3D maps of the fractures produced.
