Argentina

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.
