Consent to use Songa Enabler at Snøhvit

Statoil has received consent to use Songa Enabler for drilling three wells at Snøhvit. Snøhvit is a gas field in the Barents Sea north-west of Hammerfest. Statoil is the field's operator. Snøhvit has been developed using a subsea production facility. The gas is transported onshore through a 143-kilometre-long pipeline to Melkøya, off Hammerfest. Production at Snøhvit began in 2007. Gas from the field contains CO2, which is separated out at Melkøya and sent back to the field for reinjection. Statoil has received consent to use the Songa Enabler mobile drilling facility to drill three wells on the field. Two of these are production wells, while the third is for reinjecting CO2. The wells are designated 7121/4 G-4 H, F-1 H and G-3 H. The two well templates are in 316 and 318 metres of water respectively. Drilling is scheduled to begin in late July 2016 and will last for 220 days in all. Songa Enabler is a semi-submersible drilling facility of the CAT D type. It was delivered by the Daewoo yard in South Korea in 2016, is registered in Norway and classified by DNV-GL.

Drilling for replenishment of Snøhvit gas

The Songa Enabler drilling rig has started drilling a new injection well for CO2 gas on the Snøhvit field off the coast of Hammerfest. Next a production well will be drilled for replenishment of gas for Hammerfest LNG. Snøhvit is still the only LNG project in the world capturing and storing CO2 separated from the well stream in a dedicated formation offshore. So far more than four million tonnes of CO2 from Snøhvit have been stored. The stored CO2 is being monitored in order to ensure that it does not mix with the main producing reservoir. A new CO2 injection well is now required. After the new CO2 injector is installed, the rig will move on to drill the first new production well at Snøhvit since the field came on stream in 2007. The drilling campaign is planned to last until Christmas. The CO2 solution project was established in 2013 in order to build and install a new CO2 injection well, replacing the original injector that over time would leak CO2 into the gas reservoir on the Snøhvit field. “Hammerfest LNG needed replenishment of gas in order to maintain the high production and capacity utilisation at the plant, while ensuring sustainable CO2 storage. This project is therefore important to Statoil,” says Geir Owren, asset owner representative for the project. In the summer of 2015 an extensive marine campaign was performed. Pipelines and a template for the CO2 project were installed and tied in to the existing subsea facility on the Snøhvit field. The new subsea facility was built and installed without injuries and well within the budget of NOK 2.5 billion. “The distance to the Barents Sea presents extra challenges with regard to mobilisation and sailing time, which requires careful planning, thorough preparations and close cooperation with the suppliers. We are pleased both with the equipment suppliers and marine operations, which resulted in successful project implementation,” says project leader Sveinung Øvretveit. The next big development step for Hammerfest LNG is the development of the Askeladd field, which is part of the plan for development and operation of the Snøhvit licence. It is expected to come on stream in 2020/2021. This development step will help ensure full utilisation of the capacity at Hammerfest LNG.

Securing rig capacity to improve recovery on the NCS

Statoil is entering into new contracts to secure increased rig capacity on the Norwegian continental shelf (NCS). The company has chartered two more rigs to be purpose-built for mature fields. The rigs will contribute further to Statoil’s efforts to improve recovery on the NCS. Songa Offshore has been awarded contracts for building the two rigs. The estimated contract value is USD 1.33 billion per rig for a fixed charter period of 8 years, with options for extensions of another 4x3 years per rig. The contracts cover two category D rigs for medium water depth. This innovative rig concept has been developed by the industry for Statoil. “Statoil is committed to maximising the value of the NCS,” says executive vice president of Development and Production Norway in Statoil, Øystein Michelsen. “We have a world-class project portfolio on the NCS with a robust production outlook. In addition to the safe and efficient development of new fields, we continue to step up our efforts to improve recovery from existing fields. We are convinced that new efforts are needed to secure a rig fleet that can handle the demanding tasks ahead.” By increasing the capacity of category D rigs, the drilling and completion of production wells will be carried out at lower costs, more efficiently and in a safe manner. Reducing rig costs is important in order to realise the values in existing discoveries. New discoveries are often made close to existing fields. Fast development of such discoveries is necessary to utilise the existing infrastructure. “In order to further revitalise the NCS, Statoil sees the need for adding new rig capacity. We are targeting the allocation of rigs and rig concepts to ensure more capacity in the market, and we are already seeing results of these efforts,” says chief procurement officer in Statoil, Jon Arnt Jacobsen. One of the new category D rigs will be used on the Norne, Heidrun and Åsgård licences, the other will be part of Statoil’s strategic rig fleet and set up for year-round operations in the Barents Sea. “We have carried out a procurement process which has generated significant interest among rig entrepreneurs, contractors and investors. Statoil committed to Songa Offshore last year to realise the first two category D rigs, these new contract awards strengthen our cooperation. The contract awards will raise exciting possibilities for Songa Offshore, but will also lead to positive spinoffs for sub-suppliers involved in producing and preparing the rigs for operation,” says Jacobsen. In connection with the contracts Statoil will provide to Songa Offshore a bridge financing covering the pre-delivery payment by Songa to the shipyard (DSME). The financing is equivalent to 20% of the total construction contracts value, offered at normal market conditions, including security.

Long-term contract for new rig design

Statoil is sending out an invitation to tender for a new type of drilling rig. It is specially-designed by the industry on behalf of Statoil for use on mature fields on the Norwegian continental shelf (NCS). The purpose is to make drilling and completion of production wells less expensive, more effective and safer, and thereby boost oil recovery. Discoveries on the NCS are getting smaller and it is becoming more important to increase drilling activity in mature fields to attain the full potential of the NCS. To meet this challenge, lower rig rates, greater drilling efficiency and access to rigs are key factors. “The rigs delivered to the NCS in recent years were first and foremost constructed for operations in deep water,” says Jon Arnt Jacobsen, chief procurement officer in Statoil. “That means that they are big and too costly for our requirements and challenges on the NCS. We are therefore taking steps to rejuvenate the rig fleet and ensure that the right rig meets the right requirements.” The specially-designed category D rig is able to operate at water depths of 100-500 metres and drill wells down to 8,500 metres. It will be a workhorse on mature fields, primarily for drilling production wells and well completion. In this way, Statoil and its partners can get more oil out of the fields. The rig has been developed in collaboration with various industry players. Statoil is issuing a tender for minimum two such rigs for work on the NCS. The contract will run for either eight years with four three-year options or for 20 years firm contract period. This is an unusually long period of contract which will reduce the risk for the drilling contractor who will build the rig. Statoil is also considering taking an ownership stake in the rig. “Statoil is taking responsibility for a long-term development of the NCS – we see that there are still big opportunities here,” says Jacobsen. “Now we need to think anew with regard to reducing drilling costs and we will see if it’s possible to achieve a more industrialised development.” It is many years since big discoveries were made on the NCS. Minor finds are made but the margins are lower. It is therefore necessary to reduce rig costs in order to realise the potential value. Small finds are also often made near existing fields. Fast developments are then important so that the existing infrastructure can be utilised. “The key to maintaining today’s production level on the NCS towards 2020 is improved recovery from existing fields and fast and effective development of new fields,” says Øystein Michelsen, executive vice president for Development and Production Norway. “In order to implement these measures it is crucial that we secure a rig fleet which is adapted to suit the assignments and which can work more effectively.” A rig like this will be able to drill and do well completions in the North Sea and the Norwegian Sea throughout the year. “The goal is that the new rig will drill 20% more effectively than conventional rigs,” says Jon Arnt Jacobsen. “This will help to counteract the cost trends in the rig market.” Plans call for the contract to be awarded in the third quarter of 2011 and the rigs to be delivered in the second half of 2014.
