Amerisur Resources announces Platanillo operations update
Thursday, Jun 15, 2017
·     Platanillo-22 producing over 800 barrels of oil per day

·     Platanillo-21 producing over 400 barrels of oil per day

·     Platanillo-25 to spud in July

·     Platanillo-24 – successful chemical treatment performed

Amerisur Resources Plc, the oil and gas producer and explorer focused on South America, is pleased to provide an update on production operations in Colombia.

On pad 2N, the recently drilled well Platanillo-22 continues to exceed expectations. Following an optimisation of the hydraulic pump design the well is now producing approximately 851 barrels of 31.5° API oil per day (bopd) under stable conditions with 0.1 % water cut.

Well Platanillo-21, has been tested at 430 barrels of oil per day (BOPD) with 62% water cut from a 5ft perforated interval in the upper U sand and 11.5ft perforated interval in the lower U sand, using a hydraulic pump lifting system. The tested oil quality the same as Platanillo-22 at 31.5 degrees API. The relatively high water cut is due to a channel in the cement over the reservoir sections which will be treated at a future date. The pre-drill production estimate for this well was in the range of 300 to 400 BOPD. The well has been placed on commercial production and produced oil is being trucked to the southern pads for export via the OBA system.

Platanillo-25, the third well from Pad 2N is currently being planned as a directional well stepping out to the south of Pad 2N, and is expected to spud in early July.

In line with the Company´s optimisation work in the Platanillo field, an organic chemical treatment was performed on well Platanillo-24. This well, in a similar manner to some other producing wells had suffered a rapid decline in production. Post the organic treatment the well is producing approximately 820 bopd in a stable manner, using a hydraulic pump lifting system. Amerisur is currently considering other candidates for similar treatments, including Platanillo-20, Platanillo-9, Platanillo-14, Platanillo-12 and Platanillo-5.
