Pinnacle Technologies successfully deployed AST to numerous engineers from Unocal. Unocal estimated an 11% reduction in completion costs after implementing AST on their hydraulic fracture treatments in the Rincon Unit, New Mexico, resulting in a total cost savings of $850,000 on 25 wells. Despite the poorer geology of the newly completed wells, well productivity was equivalent to the older wells with `conventional` fracture treatment designs. Pressure build-up tests also confirmed the improved fracture treatment results: propped fractures of AST-treatments appeared at least twice as long as fractures from conventional treatments, even though completion costs have been reduced.
