Juan Maria Garoby, director of YPF's unconventionals business unit, detailed the company’s five year, $37 billion investment plan at a luncheon of the local branch of the IAPG Argentine oil trade group.

The plan targets 29% oil and gas production gains over five years by harnessing drilling economies of scale to slash well costs by 55%.

University of Houston engineering professor Michael Economides, who recently published a paper evaluating the investment plan, was among those who peppered Garoby with questions on the plan but got few specifics in return.
