Ecopetrol S.A. said Wednesday that it has made an “important” ultra-deepwater discovery at its Kronos-1 well in offshore Colombia.

The Kronos-1 well was drilled to a a depth of 12,200 feet in 5,195 feet of water in block Fuerte Sur, 33 miles off the Colombian coast in the Caribbean Sea, Colombia’s Ecopetrol said.

Texas-based Anadarko Petroleum operates the block with a 50 percent interest.

Ecopetrol holds the remaining 50 percent interest.

The well encountered a net pay thickness between 130 to 230 feet of gas bearing sandstones.

Ecopetrol and Anadarko’s integrated technical teams are continuing to evaluate the Kronos discovery results.

“This discovery proves the geological model proposed for an unexplored area with high hydrocarbon potential,” Ecopetrol said.

Drilling operations at the well are ongoing to reach a deeper target to determine possible additional results.

“These results are very important and confirm the potential of the Colombian Caribbean petroleum system in a vast area and are aligned with Ecopetrol´s new strategy, in which one of the key areas is the exploration on high potential marine basins,” Ecopetrol president Juan Carlos Echeverry said.

In 2012, the Ecopetrol and Anadarko partnership undertook exploration in the South Caribbean in blocks Fuerte Norte, Fuerte Sur, COL5, URA4 and Purple Angel.

Once activities at Kronos-1 are concluded, the drillship Bolette Dolphin will move to the Fuerte Norte Block to continue drilling the Calasu-1 well, located about 100 miles north east of Kronos-1.
