The company said first production from the Manta 2A well was received on Sunday at the newly upgraded Crystal Ocean floating, production, storage and offtake vessel.

This week, the other three oil producers, Basker-2, -3 and -5 will be brought onstream, the gas compressor will be commissioned and gas re-injection to Basker-4 will begin.

Full-field production follows a six-month extended production test at the $330 million project, which ended in August. As a result of the EPT, technical consultants, Gaffney Cline and Associates upgraded reserves 33% to 39.2 million barrels (MMbbl).

Since work on the project began almost two years ago, the proved and probable oil reserves have increased nearly 70%, after deducting EPT production.

Anzon said another announcement would follow once full rates, expected at 25,000 barrels of oil per day and gas injection of up to 35 million cubic feet per day, were achieved.

Chairman Steven Koroknay said the two-year project had been a “very significant achievement” for the Anzon/Beach Petroleum JV and its contract project manager, Upstream Petroleum.

Anzon and Beach Petroleum are equal partners in the Basker/Manta project.
