Songa Dee returns to work for Statoil

Songa Offshore AS (Songa) has announced that its ‘Songa Dee’ rig completed its SPS (Special Periodic Survey) in Invergordon, Scotland and left the yard on the 16th November 2014. Since that time the rig has finalised the repair and installation of one of its main engines and has performed incline and verification testing. The rig is currently located at the coast of Norway and it is awaiting improved weather conditions to move to the drilling location at the Gullfaks field to continue its work under the Statoil contract.

Songa Dee given approval to work on Gullfaks

The PSA has given Statoil Petroleum AS (Statoil) consent to use the Songa Dee mobile drilling facility for production drilling on Gullfaks satellites, well template P. The consent entails an extension of an existing consent for Songa Dee at Gullfaks issued in June 2011. Statoil has now increased the number of templates on Gullfaks satellites, and has therefore applied to the PSA for consent to use Songa Dee for production drilling of P, which is one of the new subsea templates. The earliest estimated start-up for the operation is mid-November.

Statoil to plug Gullfaks South exploration well with Songa Dee

Statoil is the operator at Gullfaks Sør, located in block 34/10 in the northern part of the North Sea. The field has been developed using a subsea solution tied back to the Gullfaks A and C facilities. Production on the field began in October 1998. Statoil has now received consent to use the Songa Dee mobile drilling facility to plug exploration well 34/10-52 A/B permanently. The well was drilled and temporarily plugged in 2011. The operation is planned to begin in late October and is estimated to last for 16 days.

Songa releases update of SPS for 'Songa Dee'

Songa Offshore AS (Songa) has released an update surrounding the scope of work for the Songa Dee’s Special Periodic Survey (SPS). The SPS has progressed according to plan, including the budget of 60 days and USD 90 million. The rig has during the yard stay achieved its certification on hull and structure by DNV, the BOP has been overhauled and lifted back on-board. The commissioning of the BOP, as well as the winch upgrades, are in its final stages. During the yard stay the Songa Dee has, however, experienced unexpected failure on one of four main engines. Critical parts for the engine are currently being prepared for re-installation. The rig is expected to leave Invergordon, Scotland, on 7 November 2014, allowing it to be back on day rate a few days later. The costs related to the engine incident will be claimed against insurance and are not expected to impact the overall yard stay costs beyond the budget.

Securing new rig for production drilling on the Norwegian continental shelf

Statoil has signed a Letter of Intent with Songa Offshore for hire of the Songa Dee rig to drill on the North Sea Gullfaks field. The contract value is around USD 378 million. The rig will carry out production drilling on the Statoil-operated Gullfaks field in the North Sea. It will be used for drilling and completing wells, and will quickly contribute to the field production. “The Gullfaks field has considerable remaining resources,” says Torstein Hole, senior vice president for Statoil’s operations west cluster. “Securing important drilling capacity on the field for the next three years, this agreement allows us to implement several measures to improve the Gullfaks oil recovery. The drilling operations will increase the field’s production volumes from 2012, which will strongly boost the recovery rate from the field.” Vidar Birkeland, acting head of procurements in Statoil, is pleased about the company securing necessary future capacity in the rig market. “We find that the agreement reflects a sustainable price level for this type of rig,” says Birkeland. “The agreement further marks the beginning of a co-operation between Songa and Statoil. We have a strategy to increase the diversity, competition and flexibility of this market. For this reason it is important to Statoil to have several rig companies operating in Norway.” Plans call for the rig to start its production assignment for Statoil in August 2011. The contract states a daily rate of USD 345,000. Statoil has an option to extend the contract period from three to four years on the same terms. The agreement is contingent on partner approval.
