Amerisur Resources announces completion of drilling with indications of oil column at Plantanillo-25

Oil and gas producer Amerisur Resources said Thursday the Plantanillo-25 well in Colombia has been successfully drilled with introductory data indicating the presence of an oil column in the U sand formation of the well.

Platanillo-25, the 20th well of the Platanillo drilling campaign, according to Amerisur, was "successfully" side tracked to a total depth of 8,620 ft measured depth, on time and budget, with preliminary log interpretation indicating evidence of 22 ft net oil column in the U sand formation.

That said, the N sand did not present net pay at this location, as expected.

Amerisur also said the side track located the production well further up dip, nearer to the Platanillo 21 well, discovering the presence of "better" reservoir quality as well as additional pay thickness, increasing the potential to deliver more sustainable production.

It now expected to initiate commercial production from the U sand in ten days, having successfully run and cemented the 7" production casing.

On completion of the Platanillo-25, the company said it will move to commence drilling at the Platanillo-27 well, a planned well north of Pad 2N in close proximity with the Platanillo-25 well, to target a bottom hole location with a U-sand structural target.

John Wardle, chief executive officer, commented: "This is a further good result on Pad 2N. I look forward to updating shareholders on the production performance of the well."
