Cuenca Neuquina, Argentina Relevamiento geoquímico de superficie en trampas estratigráficas

Neuquen Basin, Argentina. Geochemical Survey in Stratigraphic Traps.<br>This area presents some difficult challenges to the continued development of this field because of its<br>structural complexity caused by intense fracturing due to the intrusion of many andesitic sills and dikes.<br>The results showed that the areal extend of the microseepage anomaly at the surface identified in the<br>North part of the area approximates the extent of the reservoir, represented by an eolic sandstone deposit.<br>Also, Low Microseepage value is related to the decrease in the quality of the reservoir.
