Improving productivity in unconventional reservoirs by utilizing petrophysical properties

Résumé fourni par la source

Understanding permeability in carbonate shales tends to be difficult to predict as the shale presents heterogeneous mineralogy, poorly nano- and micro-pores system, carbonate secondary porosity as dissolution may be also present. Understand fluid types in this reservoir is also critical for effective permeability modelling and consequently design the hydraulic fracturing geometry, injection rate and treatment size, the horizontal spacing optimization and well trajectory design. In this study, we developed a petrophysical characterization to evaluate optimum zones selection and stimulation design optimization in the Pimienta Formation, Mexico. The petrophysical model included facies model, porosity, water saturation and permeability. The results are indicating that best properties are found in Medium Pimienta towards to the Lower Pimienta Section.
