Australia-based Tap Energy holds a 30% interest, while Thailand-based Northern Gulf Petroleum owns the remaining 10% stake.
Production from two wells is increasing from the initial combined rate of 2, 200 barrels per day and is estimated to reach a peak rate of about 15,000 barrels per day in the first quarter of 2015.
Proved and probable reserves contained in Manora’s primary reservoir, and recoverable by natural depletion, are expected to be in the order of 20 million barrels (gross).
The field is expected to have an 11-year economic life, which may be further improved if discoveries are made within tieback distance.
The development drilling programme icludes drilling and completion of about 15 wells, including ten producers and five injectors.
The joint venture will have invested about $300m in the development by the end of the first quarter of 2015.
The Manora field was discovered in November 2009 by the Manora-1 exploration well, which flowed at a rate of more than 9,000 barrels of oil per day from three zones.
The field was further appraised with the drilling of a further three wells. Field development was approved in July 2012.
First oil from Manora followed the hook-up and commissioning phase and parallel operations drilling of the first four production wells.
All platform facilities were built in fabrication yards in Thailand. The facilities include a wellhead processing platform connected through subsea pipelines to a floating storage and offloading vessel.
