Mangahewa Expansion Project
Todd Energy committed to the Mangahewa Expansion Project in 2011 after securing a 10 year gas sales agreement with Methanex. The project involves an investment of around $850 million over a 5 year period.
The Mangahewa gas-condensate field was originally discovered in 1961, but deemed sub-commercial at that time. The field was rediscovered in 1997 by Mangahewa-02, and has been in permanent production since September 2001, when dedicated high pressure gas treatment facilities were commissioned within the boundaries of the McKee Production Station.
Shortly after Todd Energy took over operatorship of Mangahewa in mid-2006, it embarked on further appraisal of the field, with Mangahewa-03 drilled and tested in 2007, and Mangahewa-04 and -06 in 2009/2010.
This ultimately resulted in Todd Energy committing to the Mangahewa Expansion Project in late 2011, after it had secured a long term gas sales agreement with Methanex for Motunui Train-1.
The Mangahewa Expansion Project involves Todd investing approximately NZ$850 million over a 5 year time frame, and, because we employ many local people and use the local service providers wherever possible, the project has brought – and will continue to bring – real economic development opportunities to Taranaki. The project includes:
- approx. 25 appraisal and development wells
- expansion of the McKee-Mangahewa gas processing capacity from 20 to 45 PJ/a (MET2)
- installation of an additional gas export line complete with a new tie-in into the Maui pipeline, and
- associated in-field infrastructure (wellsite facilities, gathering lines).
The natural gas produced will provide natural gas to:
- Methanex, through our 10 year agreement, enabling them to increase output of methanol for end use in the production of many household products.
- generate electricity during periods of high demand; it will
- be piped for direct use by homes and businesses, and
- will be processed into LPG for use in the South Island.
