Recoverable volumes from Troll phase 3, which produces the gas cabinet in Troll Vest, are as high as 347 billion cubic meters of gas. Converted to oil equivalents, it is 2.2 billion barrels, about the same amount as the first phase of the Johan Sverdrup field. The investments are about NOK 8 billion.
 
The project is unique due to exceptional profitability, low climate emissions in that the development is connected to already electrified Troll A. The work has been completed in a demanding period of pandemic with impeccable HSE results. The budget has been kept and after a postponement of the start-up time due to the pandemic, the project has managed to recover some of the postponement. Instead of starting in October, it was now in August.
 
A large proportion of Troll's revenue goes to the state through taxes and the state's holdings. Troll has for 25 years contributed huge income and will continue to do so for many years. The annual government revenue from Troll phase 3 project alone is estimated at NOK 17.4 billion 2021 on average.
 
For 25 years, Troll A has changed energy consumption in Europe from coal to gas with much lower climate emissions and was the first platform on the Norwegian shelf to be electrified, as early as 1996.
 
The partnership in the Troll license consists of Equinor, Petoro, Shell, TotalEnergies and ConocoPhillips.
