Norway’s Statoil and its partners have made an oil discovery of up to 130 million barrels of oil in the Verbier sidetrack well in the outer Moray Firth on the UK Continental Shelf.
The preliminary results suggest the discovery could range anywhere between 25 and 130 million barrels of oil.
“This is an encouraging result for Statoil and the UK team. We have proven oil in good quality sands with good reservoir properties, but significant work remains, most likely including appraisal, to clarify the recoverable volumes and to refine this range,” says Jez Averty, senior vice president Exploration in Norway and the UK.
The partnership will continue to assess the data and plan further appraisal to determine the exact size of the discovery. The partnership will also seek to determine the commerciality of the discovery in addition to maturing additional opportunities within the P2170 licence.
The Verbier main wellbore encountered a water-filled sand and the decision was made to drill a sidetrack to assess the remaining potential up-dip.
“The results show that we made the right decision to sidetrack the well and this discovery proves that there could be significant remaining potential in this mature basin,” says Jenny Morris, vice president for Exploration in the UK.
The Mariner Segment 9 well encountered two oil-filled sands in the Heimdal Formation and a thin oil column in the deeper Maureen Formation. A comprehensive suite of data was acquired which will be used to establish the extent of the Heimdal sand bodies, the impact on resources and future drainage strategy for the main Mariner field together with the potential for tie back of additional resources.
Statoil is the operator of Verbier with a 70 per cent stake. Jersey Oil and Gas has an 18 per cent holding and CIECO Exploration and Production has the remaining 12 per cent.
