UK-based oil and gas producer and explorer Amerisur Resources has announced that its sixth well Platanillo-10 of the Platanillo drilling program has encountered oil.
The Platanillo-10 well situated on platform 5 South (5S) was deviated about 1,865ft north east of the platform and intersected 80ft gross and 68ft net pay in the U sand and T sand.
Platanillo-10 is expected to be completed and commence production in March.
Amerisur Resources re-entered the Platanillo-1 in 2007 and was sidetracked to a location about 2,485ft to the east to outline the oil columns in the Platanillo reservoirs.
The sidetrack well is named Platanillo-1 ST1, which found 22ft net pay interval in the U sands, of which 7ft was perforated, producing 530 barrels of oil per day on test.
The well has now been placed on commercial production.
Amerisur Resources chief executive John Wardle said the company has intersected oil during the drilling of Platanillo-1 ST1 sidetrack.
"To encounter producible oil at that position in the structure augurs well for the size of the eventual recoverable resource in the Platanillo field," Wardle added.
"Additionally, this great result has significantly de-risked the northern section of Platanillo. Based on our 3D seismic and this well data I am confident we will develop significant reserves volumes in the northern part of the block.
"Platanillo-10 continues our unbroken 100% commercial success record, with a very good oil column in excellent quality reservoirs and exactly in line with our geological model."
