Oil and gas operator Spirit Energy is planning to drill a new well at the Chiswick field in the southern North Sea in a bid to extend the site’s life.

The drilling campaign is expected to bring around a further 50 billion cubic feet of gas on-stream.

The new well will be developed with a £75m investment from Spirit and will be drilled using Noble’s Hans Deul jack-up rig.

Spirit Energy North Sea director Fraser Weir said: “Having already produced billions of cubic feet of gas since coming on stream 11 years ago, we are delighted that the hard work and collaboration of our teams in both the UK and the Netherlands has led to us continuing our investment in the Chiswick field and extending the life of a key part of our portfolio.

“This is just one part of a busy rig programme for Spirit Energy in Europe this year as we explore for fresh discoveries.”

“This is just one part of a busy rig programme for Spirit Energy in Europe this year, as we explore for fresh discoveries, maximise the potential of existing fields and plug wells which have ceased production.”

The Chiswick field is located within Spirit Energy’s Greater Markham Area, which also comprises the Markham, Grove, and Kew fields.

In the last year, the Greater Markham Area fields produced 23 billion cubic feet of gas net for the company.

The infill well is set to become the fifth drilled in the field, and the first since 2010.

The company noted that the Hans Deul will begin preparatory work at the field in April this year.

Recently, Spirit has secured 11 licences in the awards in predefined areas (APA) around the Norwegian Continental Shelf.
