Egdon Resources has provided an update on operations at the Dukes Wood-1 well in Nottinghamshire licence PEDL118. The Dukes Wood-1 well recommenced the drilling operations on January 11, 2010 using the British Drilling and Freezing rig 28 (BDF28).
The well reached a total depth of 793mt measured depth (615.7mt true vertical depth) on January 20, 2010. All the formations were penetrated very close to the pre-drill prognosis.
Oil shows were observed in a number of the target formations while drilling. The analysis of the wireline log data over the primary objective for this well, the Ashover Grit unit 5 (AG5), indicates a total net pay thickness of 4.7mt (4mt vertical thickness) with porosity averaging 20% and oil saturations in excess of 50%.
The company said that an extended well test will determine the full production potential of the AG5 and other zones. The well has been cased and perforated over a 5mt interval in the AG5 and completed for test production. Testing operations are expected to commence during February 2010, as soon as all approvals are obtained and equipment and personnel mobilised.
Four other intervals of interest have also been identified within the well, the Sub-Alton Crawshaw, Loxley Edge Rock, Ashover Grit unit 4 and Wingfield Flags. The total potential net pay across these formations is 21.64mt (measured depth) and these zones may be perforated and tested at a later date.
Egdon holds a 65% interest in and is operator of the PEDL118 licence. Joint venture partner Terrain Energy holds a 25% interest in the licence and on completion of the on-going farm-in Angus Energy will hold a 10% interest.
The BDF28 rig is currently being rigged down and will then be moved to the Kirklington oil field to drill a sidetrack of the Kirklington-2 production well.
Mark Abbott, managing director of Egdon, said: “The Dukes Wood-1 well provides the first modern data from the Eakring-Dukes Wood field and will provide useful information for the development of our long term plans to rejuvenate the field.
“We are encouraged by the initial analysis of the well results which have indicated the presence of a number of zones capable of oil production. We now look forward to the outcome of the production testing of the Ashover Grit and potentially other formations over the coming months. Our near-term focus now turns to the Kirklington sidetrack in adjacent licence PEDL203.”
