Royal Dutch Shell Plc has launched the sale of its stakes in two oil fields and two pipelines in Norway, according to a sales document seen by Reuters.

Shell is selling its 6.45% interest in the Kvitebjorn field and pipeline and its 3.225% interest in the Valemon Unit and Valemon Rich Gas Pipeline, according to the document.

The offshore assets are operated by state-controlled Norwegian oil firm Equinor ASA. They access to a resource of 17 million boe with an annual daily production of 7,200 boe, according to the document.

The assets are expected to raise between $50 million and $100 million in total, according to industry and banking sources.

A Shell spokesman said: "Shell continuously evaluates opportunities for our global portfolio including our position in Norway. We are not able to comment on activities that we may or may not engage in due to commercial sensitivities, and have nothing more to add at this time."

Shell is currently a partner in 34 production licenses offshore Norway and operates 14 of them, according to its annual report.

In 2018, Shell sold several of its Norwegian assets to OKEA, a Norwegian producer backed by private equity firm Seacrest Capital, for $566 million.
