Indonesia's Mako Field Gets Resource Boost
Singapore-registered Conrad Petroleum has significantly raised its resource estimates for the 2017 Mako gas discovery off Indonesia following a successful drilling campaign, its partners Coro Energy and Empyrean said in London stock filings on April 14.
The partners sank two appraisal wells at Mako last year, Tambak-1 and Tambak-2, which demonstrated the presence of well-developed, high-quality reservoir sandstones with a common gas water contact across the Mako structures, the companies said.
The Mako field is now estimated by Conrad to hold 493bn ft3 (13.96bn m3) of best-estimate recoverable gas, marking a 79% increase from the figure according to independent assessment conducted by Gaffney Cline & Associates (GCA) in January 2019. Conrad now places the discovery's low- and high-estimate resources at 323bn ft3 and 666bn ft3, up 76% and 70% respectively.
Conrad operates the Duyung production sharing contract containing Mako with a 76.5% stake, while Coro has 15% and Empyrean has 8.5%. The partners are reviewing their development plans for Mako, forecasting that the field could flow at a plateau rate of 150mn ft3/day. GCA has been hired to update its assessment.
