Statoil Begins Mariner Production Drilling

  • Operations & Maintenance

Statoil informed that the production drilling has started on the company’s operated Mariner field in the UK North Sea.

The Mariner field is located on the East Shetland Platform of the UK North Sea, approximately 150 kilometers east of the Shetland Isles.

Up to five wells will be drilled before the Mariner A platform hook up and commissioning activity starts next summer. First oil is expected to be produced from Mariner in 2018, Statoil said.

Hedda Felin, managing director, Statoil Production UK said, “This is an exciting period for us as a UKCS operator as we transition from the planning phase to active offshore operations.

“Predrilling enables production to reach plateau levels more quickly after the start of operations on Mariner A. It will also be an important learning period for us in terms of understanding the reservoir and identifying potential efficiencies for future wells, with safety and the protection of the environment being our fundamental priorities.”

The Noble Lloyd Noble jack-up rig is currently positioned over the Mariner jacket which was installed in 2015. The first production wells will be drilled through a well deck on the jacket.

Up to five wells will be drilled before the platform topside modules arrive mid-2017. In total up to 100 reservoir targets could be drilled over the lifetime of the Mariner field, based on the current development strategy.

Statoil has worked closely with Noble Drilling and Schlumberger to ensure safe and cost-effective operations. The rig contract was awarded to Noble Drilling in 2013, followed by the contract award for integrated drilling and completion services to Schlumberger in 2014, the company noted.

The Mariner topside modules are currently under construction at Daewoo Shipbuilding & Marine Engineering (DSME) in South Korea and sailaway is expected in the first half of 2017.

Mariner is one of the largest projects currently under development in the UKCS. Contracts worth over £1 billion have been awarded to date to the UK supply chain by the project.

Statoil (U.K.) Limited is the operator of Mariner with 65.11% equity. Co-venturers are J.X. Nippon Exploration & Production (UK) Limited (20%), Siccar Point Energy (8.89%) and Dyas Mariner Limited (6%).
