Equinor will drill new wells in the Martin Linge field in the North Sea after conducting an in-depth study of wells drilled in the field before the company took over Total’s operation in 2018, the Norwegian oil company writes in a statement Tuesday.
“This review concludes that several of the wells do not have the necessary barriers, so Equinor plans to drill new wells in order to start safe production,” the report said.
Cost of a billion
According to Equinor, the wells are considered safe as they are now, but will remain plugged and under surveillance until pressure in the formation has been reduced by production from other wells.
– All security systems are based on the fact that we have two independent barriers and that is what we have had a review. There are many elements, it can be training, cement, etc., but both internal and external experience have spent a lot of time mapping what it looks like and we have come to the conclusion that we do not have the necessary barriers and therefore we decided to make sure. for a safe start, says Acting Executive Vice President Geir Tungesvik for Technology, Projects and Drilling at Equinor.
Equinor now plans to drill up to three new gas wells in addition to the two remaining wells in the development and operation (PDO) plan so that the field can produce as originally planned.
The total cost of drilling up to three new wells is about two billion crowns, according to Equinor.
Billions of cost overruns from before
This is not the first time trouble has arisen for Martin Linge’s field. When Equinor bought Total in 2018, the project was already behind schedule. The field was originally due to go into production in 2016, but the previous year, Total announced that commissioning had been postponed until 2018.
It is especially the construction of the platform of the platform in South Korea that has become more expensive and more difficult than planned. It also didn’t help progress when Total’s project was hit by a fatal accident at the Samsung shipyard in South Korea in 2017.
Now the start-up has been postponed until 2021 and the cost overruns have become huge.
When the state budget was presented in October last year, the excess was NOK 25.7 billion, which corresponds to an 85 percent cost overrun.
Martin Linge had a cost of NOK 30.4 billion in 2019 when it was adopted under Total in 2012.
It has not ruled on the requirements.
– We have informed Total about the challenges we have, but we have not commented on what we will do in the future, says Tungesvik.
It confirms that the wells were drilled by Total.
– Could it be relevant to charge them costs?
– We have not commented on the matter. As I said, we have informed you about it.
– Two billion are sober?
– Two billion is the estimate for up to three wells, so I think we have to keep in mind that the corona still exists and if it had an eruption on a drilling rig or rig, it would change the picture somewhat. But this is the estimate we have now, says the acting executive vice president.
Press manager Gaël Baudet at Total says the following in a comment to DN:
“Total recently learned of Equinor’s opinion that some of the wells drilled at Martin Linge do not have the necessary barriers. This information is new to us and we are reviewing the case. We have no further information at this time.”
Owner with Petoro
There will be four gas wells that were previously drilled prior to 2018, which have proven deficiencies in the well barriers and are therefore not considered suitable for safe production.
Equinor is the largest owner and operator of Martin Linge with 70 percent. The state-owned Petoro is the only partner with a 30 percent stake. Petoro has also conducted an independent assessment of well barriers supporting Equinor’s opinion.(Terms)Copyright Dagens Næringsliv AS and / or our suppliers.
