New Zealand company Todd Energy will go to court next week claiming damages of $274 million from its international partners in Taranaki's Pohokura gasfield.
Todd alleges that from 2006 and each year since then, oil giant Shell and Austrian company OMV had constrained production of the gasfield to 70 petajoules of gas when it could produce at least 85 petajoules.
In the past, Todd has said each extra petajoule would mean millions of dollars in extra revenue, but it has now put a total figure on its damages claim - $274m.
The case will start in the High Court at Wellington on Monday, the Dominion Post reported.
The multibillion-dollar Pohokura field has reserves of 700 billion cubic feet of gas and 42.8 million barrels of light oil condensate. Todd holds 26 percent of the field, with Shell holding 48 percent and OMV 26 percent.
In a statement, Todd said that under the Pohokura joint venture, each party had the right and obligation to take and sell its share of the total production "capable of delivery at any given time" and the constraint on production to 70 petajoules a year was a breach of the Commerce Act.
It also had the purpose or effect of controlling or maintaining the price of gas and also breached the Act by limiting production and supply.
Todd said the alleged off-take agreements were also a breach of the Crown Minerals Act.
Todd was also seeking injunctions from the court to stop the constraint on production, which was still continuing, it said.
All the allegations have been denied by Shell and OMV, which said they would not comment on matters before the court.
