The Leverett discovery is located to the northwest of the Brodgar Field, and is delineated by four wells that all encountered condensate-bearing Lower Cretaceous Britannia Sandstone. Improved seismic definition combined with knowledge gained from the Finlaggan field has given Zennor encouragement that Leverett could be tied back to Britannia. The Greenwell Prospect is an extension of the Palaeocene Callanish Field, which has produced 58mmbo in the last nine years. Greenwell exhibits the same DHI response as Callanish and lies immediately to the northwest of the field. Drilling on either the Greenwell Prospect or the Leverett Discovery had been anticipated 4Q2020, but has been delayed. Meanwhile, planning for a pilot hole and horizontal side-track on Greenwell and a vertical appraisal for Leverett is ongoing.
