The well, mapped with 3-D seismic technology, will be drilled to a target depth of 13,000ft to intersect the Mirador, Guadalupe and Une formations on the 345,592-acre block.
Gulf United Energy chairman and chief executive officer John Connally said the drilling of the third well is a significant step in moving forward with the company’s exploration program on the Block CPO-4.
"The Zorro Gris is the second well currently being drilled by the Company," said Connally.
"The Cañaguate-1 well, which is located on the 570,452-acre SSJN-5 block in the Lower Magdalena Valley in northwest Colombia, was spudded in late July."
The company owns oil and natural gas properties in Colombia and Peru.
