Argentina

Shell has reaffirmed its commitment to the shale business and views it as a growth opportunity moving into the 2020s

With the easy conventional oil in Argentina having been produced, one remaining way to find new oil in existing fields is to convert fields from primary or secondary production to secondary or tertiary production, respectively.

The Loma Alta Sur (LAS) field is a multilayer fluvial sandstone reservoir in the Neuquén basin of Argentina. Colloidal-dispersion-gel injection was considered a viable strategy to improve oil recovery in the field after early water breakthrough.

One of the most promising targets for resource-rock stimulation in South America is the Vaca Muerta (VM) shale in western Argentina.

This paper discusses aspects of water logistics necessary during the well-completion phase, fracture-treatment designs applied in Vaca Muerta, and laboratory studies performed on flowback and produced water to help evaluate the potential for water reuse.

A successful pilot test of polymer flooding was conducted in the San Jorge Gulf basin.
