GeoPark discovered oil at the Chachalaca 1 exploration well located on the Llanos 34 block in Colombia. The company drilled and completed the well to a total depth of 12,270 ft and tested the Mirador formation with an electrical submersible pump. It flowed oil of 30 °API at a rate of approximately 1,100 B/D with a 6% water cut. Further production testing will be conducted to determine stabilized flow rates.
