Amerisur Resources Plc, the oil and gas producer and explorer focused on South America, is pleased to provide an update on Platanillo-21, the second well on Pad 2N, the northern extension of the Platanillo Field.
Platanillo-21, the 19th new well of the drilling campaign, in addition to the three successful sidetracks, has been successfully drilled and cored as a short deviation directional well, aimed at the crest of the mapped structure, to a total depth of 8,447ft measured depth, on time and budget.
The well was cored over the N sand, M2 sand, A Limestone, U (upper and lower) and T sands. The reservoir cores recovered from Platanillo-21 are currently being analysed with the objective of physically determining the properties of the reservoirs at this northern extension of the Platanillo field. This will allow a refinement of the reserves model and will serve to calibrate both Logging While Drilling and wire line run electric logs.
Log interpretation indicates the presence of 36ft net oil column in the U sand formation and a 17ft net oil column in the T sand formation using both Schlumberger logging-while-drilling and Schlumberger wire line tools. The N sand did not present net pay at this location, in line with the pre-drill model. The M2 sand and A limestone core data are being evaluated to determine their potential as pay zones.
The 7" production casing has been successfully run and cemented and the Company expects to initiate commercial production from the U sand.
John Wardle, Chief Executive Officer, commented:
"This is a further good result on Pad 2N. I look forward to updating shareholders on production performance from this well."
