Exploration for deep gas in the Devonian Chaco Basin of Southern Bolivia: Sequence stratigraphy, predictions, and well results

OSTI ID:542916
In mid 1991, a team was assembled in Texaco`s Frontier Exploration Department (FED) to define the hydrocarbon potential of the Chaco Basin of Southern Bolivia. The Miraflores No. 1 was drilled in the fall of 1992, for stratigraphic objectives. The well confirmed the predicted stratigraphic trap in the Mid-Devonian, with gas discovered in two highstand and transgressive sands. They are low contrast and low resistivity sands that are found in a deep basin `tight gas` setting. Testing of the gas sands was complicated by drilling fluid interactions at the well bore. Subsequent analysis indicated that the existing porosity and permeability were reduced, such that a realistic test of reservoir capabilities was prevented.
