520			_aChihuido de la Sierra Negra field is the main Repsol-YPF SA oilfield. It is located in the northeastern margin of Neuquén Basin. Main reservoir units are aeolian sandstones from Lower Troncoso Member (Huitrín Formation, Aptian) and Avilé Member (Agrio Formation, Hauterivian), with more than 1,000 MM stb oil in place. In 1993 oil was discovered in a thick basic intrusive body intruded pulling apart evaporitic rocks from Upper Troncoso Member (Aptian). The starting of the oilfield development was disappointing due to difficulties in locating wells with the 2D seismic that was available at that moment and the low production rates. 3D-survey acquisition, identification of fracture zones and drilling of horizontal wells increased dramatically the production rates. In this moment the field is under development, producing 12,000 bl/d with 11 wells. This article discusses technical ideas, which have contributed the successful development of a nonconventional reservoir.
