Amerisur Resources Plc provided an update on Platanillo-27, the fourth well on Pad 2N, in the northern extension of the Platanillo Field on Dec. 14.

Platanillo-27, the 21st well of the Platanillo drilling campaign, has been successfully drilled as a medium deviation directional well, to a total depth of 9,600 ft (2926 m) measured depth, on time and budget.

The well was aimed at the crest of the northern part of the mapped structure and log interpretation indicates the presence of 12 ft (3.6 m) net pay in the “U” sand formation and a 9 ft (2.7 m) net pay in the “T” sand formation using Schlumberger Ltd. (NYSE: SLB) LWD tools. The “N” sand was not a target at this location. The well also intersected the “M2” sand and “A” limestone and log data is being evaluated to determine their potential as pay zones.

The seven inch production casing has been successfully run and cemented and the company expects to initiate commercial production from the “U” sand.

“I am pleased to announce another good result on Pad 2N, the fourth successful well of our new Platanillo campaign. I look forward to updating shareholders on the production performance of the well,” John Wardle, CEO, said.
