On 14 December 2017, the PSA carried out an audit of Statoil, focused on the company's well planning and preparations for production drilling of wells at Johan Castberg.
Our objective was to carry out an audit of the operator's front-end planning of wells and drilling operations in order to verify processes for producing a risk picture for drilling operations and the company's hardening up of drilling and well plans. Included topics were well control, working environment, logistics and emergency preparedness.
The audit identified two improvement points relating to analyses and calculations for decision support and location-specific winterisation measures and operating manuals. We have asked Statoil to provide their assessment of these matters by 30 April.
Discovery 7220/8-1 Johan Castberg is in the Barents Sea, 110 kilometres north of the Snøhvit field. The water depth is 370 metres. Johan Castberg consists of the three discoveries 7220/8-1 (Skrugard), 7220/7-1 (Havis) and 7220/7-3 S (Drivis), proven between 2011 and 2013. The reservoirs contain oil and gas in Lower to Middle Jurassic sandstone. The discoveries will be developed together and the plan for development and operation (PDO) was submitted to the authorities in December 2017. The development concept includes a production, storage and offloading vessel
