Maria field development plan approved, Wintershall says


KASSEL, Germany — Wintershall and its partners, Petoro and Centrica, have received approval from Norway’s Ministry of Petroleum and Energy for the plan for development and operation (PDO) for the Maria development, offshore Norway.


Norway has approved the PDO for Wintershall’s Maria development.

Wintershall submitted the PDO to the Ministry of Petroleum and Energy on May 5. The approved development solution for Maria field involves two subsea templates located on the ocean floor tied back to several host installations in the area.

“This is another important landmark for Wintershall in Norway. In a challenging oil price environment, we are moving ahead with the execution of this key development project. Through Maria we are investing in one of our core international regions, which demonstrates our commitment on the Norwegian Continental Shelf,” said Hugo Dijkgraaf, Wintershall Maria Project Director.

Under the approved development solution, the Maria reservoir will be linked via a subsea tieback to the Kristin, Heidrun and Åsgard B production platforms. The Maria well stream will go to the Kristin platform for processing while the supply of water, for injection into the reservoir, will come from the Heidrun platform, and lift gas will be provided from Åsgard B via the Tyrihans D field subsea template. Processed oil will be shipped to Åsgard field for storage and offloading to shuttle tankers. Gas will be exported via the Åsgard Transport System to Kårstø.


Dijkgraaf added, “By developing this innovative solution that utilizes existing infrastructure in the Norwegian Sea, we are strengthening our position as a subsea operator and generating substantial value for the partnership and the whole supply chain.”

A significant number of contracts have already been awarded for the Maria project, notably the subsea production system to FMC Kongsberg and the contract for pipeline and subsea construction to Subsea 7.

Investments in the Maria development are estimated at around $1.85 billion (15.3 billion NOK) (100%), including development drilling. Recoverable reserves on the field are estimated at around 180 MMboe, of which the majority is oil. The planned production startup for Maria is in 2018.

Maria field is approximately 20 km east of Kristin field and about 45 km south of Heidrun field in the Halten Terrace in the Norwegian Sea. Wintershall Norge is the operator of the license with a 50% share. Petoro has a 30% share and Centrica Resources (Norge) owns the remaining 20%.
