Solid Energy is refocusing its coal seam gas development work to Taranaki after successfully proving the technology in New Zealand conditions at its Huntly coal seam gas demonstration plant in the Waikato.
The latest independent appraisal of Solid Energy’s coal seam gas acreage in New Zealand’s Taranaki region indicates that Solid Energy now has 858,000 million cubic feet (mscf) of contingent resources. In energy terms, this is ~900 petajoules (PJ), the equivalent of 45 years’ supply for a combined cycle gas turbine like the 400MW generation unit at the Huntly Power Station.
The assessment, by Dallas-based Netherland, Sewell and Associates Inc (NSAI), is based on exploration results to 31 December 2011. Solid Energy previously reported its contingent (2C) coal seam gas resource holdings at 30 June 2010 as the equivalent of 190 PJ.
Dr Steven Pearce, Solid Energy’s General Manager Gas Developments, says the four-fold increase in contingent gas resources is extremely encouraging. “Dan Paul Smith, lead author of the report, says that based on NSAI’s knowledge of similar field developments, the best estimate (2C) resources have a reasonable chance of being commercial,” Dr Pearce says.
The Taranaki region is the centrepiece of New Zealand’s oil and gas production, with a number of downstream gas processing plants and associated petrochemical industries. The country’s two main gas transmission pipelines run to the west and north of Solid Energy’s coal seam gas tenement.
