The reservoir encompasses 40 km2 of area of fine-grained marine rocks with an average gross thickness of 50 meters.This paper presents the current state of development in this unconventional tight gas reservoir, mainly composed by interbedded wackes and siltstones. The petrophysical characterization was based on electrical well logs and well cores analysis such as: X-ray diffraction, infrared spectroscopy, and porosity and permeability measurements. It was determined that the best petrofacies corresponds to wackes with secondary porosity, due to grains dissolution. With an average low permeability (<0.1mD), the use of hydraulic fracturing for reservoir ś stimulation is mandatory, in order to ensure commercial production. Fracture design is managed within a threshold of operational net pressure in order to contain the fracture within the reservoir thickness. Currently, 150 massive hydraulic stimulation treatments have been carried out (one stage per well) mainly, using treated water or hybrid (treated water and linear gel) as fracture fluid .Based in 3D seismic, we interpret a subtle, west-southwest dipping monocline without prominent structural faulting and closures. However, a polygonal fault system (PFS) is interpreted from a combination of seismic horizon and volume attributes. PFS location have been accounted for development drilling (PAD) design as they might cause partial reservoir compartmentalization and possible control in the orientation of the induced hydraulic fractures.Currently, there are more than 100 wells producing wet gas with a 50-60 °API condensate. Initial flow rates ranges from 20 Mm3/d to 100 Mm3/d and the most productive zone it is located to the northwest part of the reservoir area. | ||
