PGNiG Upstream Norway and its partners decided to move to the select phase of the project, during which key technical decisions regarding the field development will be made. This will lead to a final selection of the development concept, scheduled for 3Q20.
The Tommeliten Alpha License Partnership approved to end the assess phase of the project as technically and economically viable concepts for development of Tommeliten Alpha had been identified. This marks a crossing of the ‘Decision Gate 1’ into select phase.
“The conclusions of the Assess Phase are in line with our expectations and confirm the validity of our decision to purchase shares in the Tommeliten Alpha. The field is economically attractive and will significantly increase our gas production in Norway," said Piotr Wozniak, President of the Management Board of PGNiG SA. “The preparatory works for the development of Tommeliten Alpha are on schedule and we assume the start of the production in 2024”.
The select phase is scheduled to last until 3Q20. During this phase several key decisions will have to be made regarding, among others, number and type of wells, Xmas trees, host and tie-in point selection as well as technical specification of subsea pipeline. These decisions will lead to a final selection of concept that will have an impact on cost, operational expenditures, risk of deferral, execution schedule and eventually first gas.
According to PGNiG estimates, the Tommeliten Alpha will increase the company’s gas production output from its Norwegian portfolio by 0.5 billion m3 per year in the first six years of the production. In addition, Tommeliten Alpha will allow PGNiG to extract approx. 0.5 million t of oil and natural liquid gas in the peak production year.
Tommeliten Alpha is a gas and condensate field with documented recoverable resources amounting to 12.8 billion m3 per year of natural gas, 5.9 million m3 of oil (approx. 5 million t) and 0.5 million t of natural liquid gas (according to the Norwegian Petroleum Directorate), equivalent to approx. 52 million boe (net to working interest owned by PGNiG).
PGNiG Upstream Norway AS purchased over 42% shares in the Tommeliten Alpha field from Equinor in December 2018. The operator is ConocoPhillips (28.3%) and other partners are Total (20.2%) and Vår Energi (9.1%).
