Statoil at FEED on Snorre C in perspective of Norway Snorre 2040

Statoil preferred TLP concept for Snorre C on tie-back

The Norwegian State-owned company Statoil and its partners, Petoro from Norway, ExxonMobil from USA, Idemitsu Petroleum (Idemitsu) from Japan, RWE from Germany, Core Energy from Norway preferred the tension leg platform (TLP) concept over a simple tie-back to develop Snorre C, the third phase of this giant oil and gas field offshore Norway.

Located approximately 200 kilometers northwest of Bergen in the Norwegian North Sea, Snorre field straddles across the Blocks 34/4 and 34/7.

Discovered in 1979, the production started only in 1992 because of the size and complexity of the field if we consider all the marginal fields that could be associated sooner or later to Snorre.

At that time the perspective is to maintain the production from Snorre until 2020.

In Snorre, Statoil and its partners share the working interests as following:

Statoil_Snorre-C-TLP_Project_Map – Statoil 33.3% is the operator

 – Petoro 30%

 – ExxonMobil 17.45%

 – Idemitsu 9.6%

 – RWE 8.57%

 – Core Energy 1.11%

With recoverable reserves firstly estimated to 830 million barrels of oil and then revised up to 1,400 million barrels of oil Statoil and its partners decided to develop Snorre in phases.

In addition Snorre holds 210 billion cubic feet (bcf) of natural gas and 5.4 million tonnes of natural gas liquids (NGLs).

Statoil to develop Snorre C TLP in view of Snorre 2040

In the previous plan to develop Snorre in the 2020 perspective, the Snorre C project was thought to be based on tie-backs to link  different subsea wells to Snorre A and Snorre B.

But in revising plans to shoot for Snorre 2040, it appeared that the existing hub made of the Snorre A TLP and Snorre B semi-submersible platform would have hard to support the corresponding expansion.

In addition to the future tie-backs to connect more fields, Statoil and its partners are also targeting to increase the recovery rate of the crude oil in the existing fields up to 60%.

To do so, Statoil, as operator, is mobilizing all its enhanced oil recovery (EOR) solutions.

These solutions use water injections, gas injections, water alternating gas (WAG) injections, and foam- assisted injections.

This Snorre C TLP will be equipped with 140 cabins.

In Snorre C, Statoil and its partners will invest $4.8 billion capital expenditure to cover the TLP, the infrastructures and the drilling activities.

Statoil and its partners Petoro, ExxonMobil, Idemitsu, Core Energy are expecting to complete the front end engineering and design (FEED) work by at the end of 2014 in order to make the final investment decision (FID) about the Snorre C TLP project on early 2015 with first production on 2021.
