Operational and production update

Amerisur Resources Plc, the oil and gas producer and explorer focused on South America, is pleased to provide an operations update including unaudited production from the Company's two producing fields for the month of July 2018.  


The Chiritza re-pumping station project continues to advance ahead of schedule. On 6 August 2018, the tie-in of the Chiritza manifold to the RODA main line was successfully performed. The Company is currently installing the booster pumps and control systems. The Chiritza station is expected to be commissioned in September 2018, on budget and ahead of schedule. Once completed Amerisur will have access to a minimum daily carrying capacity of 9,000 bopd through the RODA system.  The Company wishes to express its gratitude to Petroamazonas EP, RODA and the Ecuadorian Government for their support in expediting this highly complex engineering operation.

Platanillo-22 Workover

Further to the announcement on 24 July 2018, the initial phase of the Platanillo-22 workover has been successful. The logs run in the well indicated that a severe degradation of the cement sheath had occurred, giving direct communication to a deeper aquifer. This communication served to reduce oil production significantly while increasing water cut and flowing water into the oil leg of the reservoir. The reason for this degradation is not known. A cement squeeze operation was performed, and subsequent logs indicated that full integrity between the oil leg and the aquifer has been recovered. The well was recompleted and partially perforated on 2 August 2018 in order to confirm the isolation at low production rates. The well is now producing approximately 360 bopd at a low pump rate, and the water cut is at 3.2% and steadily declining. This water is assumed to be a product of the water flowed into the oil leg while the aquifer cross flow was occurring. The well will remain under observation at these parameters for approximately a further five days, after which a further perforation and pump increase will be performed to increase production rate.


The Company expects to mobilise Rig D-10 to drill Pintadillo-1 once the ongoing work on Platanillo-22 is completed. A further announcement will be made on the date of spud. The N Sand anomaly at Pintadillo is one of four such anomalies identified by the Company in the central part of the Platanillo block. It is estimated to hold P50 resources of 11.44 mmbo.

July production                                              

Total production during the month of July was 150,911 BO, equating to an average daily production of 4,868 bopd, with peak daily production of 5,119 bopd. July production was impacted by the work on Platanillo-22.  Total OBA export volume was 121,785 BO, equating to an average daily throughput of 3,929 BO, with peak daily throughput of 4,547 BO. The data has not yet been approved by the Colombian Agencia Nacional de Hidrocarburos (ANH) or national customs and tax authorities DIAN and may be subject to revision.


John Wardle, CEO of Amerisur Resources said:

"I am delighted the Chiritza re-pumping station upgrade is on budget and ahead of schedule and am grateful to the Ecuadorian Government for their support in this complex engineering project.  July production was impacted by the work on Platanillo-22, which to date has been successful.  We are ready for the upcoming drilling programme and I look forward to updating shareholders on its progress."
