Cluff Natural Resources - Operational and Licence Update

Cluff Natural Resources Plc, the AIM quoted natural resources investing company with a high impact exploration and appraisal portfolio focused on the Southern and Central North Sea gas basin, is pleased to provide an operational update in relation to its portfolio of UK exploration licences as well as applications for additional licences which have the potential to significantly enhance the licence portfolio. 


32nd Offshore Licence Round


Following success in the previous major offshore licensing round in 2018 when the Company was awarded six licences, the Company is pleased to confirm that it has submitted multiple applications for additional licences in the UK Oil & Gas Authority's latest 32nd UK Offshore Licensing Round.


The Company's applications are focussed on its current core operational areas in the Southern Gas Basin and Central North Sea and are designed to be complementary to the existing portfolio. The blocks applied for contain oil and gas prospects that are consistent with the Company's strategy of growing its licence portfolio by:


·    Identifying and targeting overlooked and/or less well understood opportunities;


·    Targeting prospects in close proximity to existing infrastructure, thus enhancing the potential for commercial development; and


·    Creating value through investment in technical work, farm outs and introducing partners with a view to drilling


All of the applications have been made solely by CLNR, with the exception of one which has been made jointly with an established international operator.


UK Oil and Gas Authority ("OGA") guidance indicates that licence awards are likely to take place in Q2 2020. Further announcements will be made in due course.


Success in this licensing round would further expand, enhance and diversify the Company's existing portfolio. The Board views the blocks applied for as being highly prospective with many containing undeveloped discoveries and exploration upside which could significantly enhance both the pipeline of potential drilling opportunities and the overall prospective resources associated with the Company's portfolio.


P2252 - Pensacola (CLNR 30%)


Licence P2252 contains the Pensacola prospect which is estimated to contain gross P50 prospective resources of 309 BCF, with additional upside on the block associated with the Lytham and Fairhaven prospects. In May 2019, the Company completed the farm-out of Licence P2252 to Shell UK Limited ("Shell"). Shell has a 70 per cent. working interest in Licence P2252, with the Company retaining a 30% non-operated interest.


The new 3D seismic survey acquired over the Pensacola prospect in August of this year, along with legacy 3D data over the Lytham and Fairhaven prospects, is currently undergoing pre-processing before being delivered to Shell's in-house processing team early in the new year for further expert analysis and interpretation.


The Board understands that delivery on the final volumes is on schedule for mid-2020 and will be followed by a period of re-interpretation with well investment decision before the end of November 2020.


The Zechstein Reef Play on Pensacola has seen significant activity and successful drilling over the last six months with Rathlin Energy announcing a significant discovery at West Newton, in East Yorkshire, where a 65m hydrocarbon column was confirmed in the West Newton A-2 well.  Offshore, ONE Dyas are reported to have recently discovered hydrocarbons in the Darach Central-1 well which was testing both a Zechstein Reef and a deep Carboniferous target.


P2437 - Selene (CLNR 50%)


Licence P2437 contains the Selene prospect which is estimated to contain gross P50 prospective resources of 291 BCF with additional upside on the block associated with the Sloop discovery and the Endymion prospect. Completion of the farm-out of 50% of Licence P2437 to Shell occurred in August 2019.


CLNR and Shell have taken delivery of the most recently processed version of 3D seismic data which has been acquired from a previous licence operator. Both parties are now actively working with the available data and continue to work towards making a well investment decision on the Selene prospect and drilling a well at the soonest possible opportunity.


P2352 - Dewar (Central North Sea) (CLNR 100%)


The Dewar Prospect on Licence P2352 is estimated to contain up to 272 million barrels of light oil (P10 STOIIP) with P50 Prospective Resources of 39.5 million barrels in the Forties Sandstone. 


As previously indicated, the Company has been running a farm-out process on the Dewar Prospect which is located close to (<5km) the BP operated Eastern Trough Area Project (ETAP) Central Processing Facility in the Central North Sea.  The prospect has generated a significant amount of interest and there are a number of established operators currently in the project dataroom.  Now that the 32nd OGA Licensing Round is complete, the Board expects this process to gather momentum and will aim to draw this process to a close in the coming months.


A feasibility study carried out by io oil & gas consulting has estimated the Dewar project to have a post-tax NPV10 of £555 million and a post-tax project IRR of 123%, in a P50 prospective resource scenario.


P2428 - Cupertino (CLNR 100%)


The Company has recently taken delivery of over 850 line kilometres of reprocessed 2D seismic over Licence P2428 which contains the Cupertino prospect.  This legacy data was originally acquired in 1992 and has been reprocessed to pre-stack depth migration (pre-SDM) using the latest processing workflows, which has resulted in a significant uplift in image quality throughout the dataset.


This newly reprocessed data is currently being interpreted in house, focussing on the early Carboniferous section which includes the TCF scale Cupertino prospect, as well as new opportunities that the Company has identified in the Zechstein and a possible westwards extension of the Rotliegendes play fairway which may be analogous to the Cygnus field.


Further technical work is required, and the Company will update the market in due course.  It is now considered likely that the area will need new 3D seismic data acquired across the prospective areas before a drilling opportunity can be fully defined and to that end the Company will seek to acquire this seismic, ideally by way of farm-out, in 2020.


P2424 - Cortez (CLNR 100%)


The Company is engaging with seismic reprocessing contractors and will seek to commence reprocessing of the legacy 2D seismic dataset over licence P2424, which includes the Cortez Prospect.  The Company expects to see a significant uplift in data quality which will help mature the Cortez prospect which has many similarities to the nearby Breagh gas field.


Delivery of the final reprocessed seismic data will be expected within six to nine months following the formal start of reprocessing.


Graham Swindells, Chief Executive Officer of Cluff Natural Resources commented:


"We have made significant investment in this latest licensing round which has allowed us to submit multiple high quality applications in our core areas of the Southern North Sea and Central North Sea where we have already demonstrated success. The blocks applied for contain a number of drilled discoveries, undrilled prospects and leads and, if awarded, will build scale, further diversifying the investment portfolio and significantly enhancing the Company's resource base which we anticipate will create a strong pipeline of future drilling opportunities."


"We are also very pleased with the significant progress being made on the existing portfolio, in particular on the Pensacola and Selene licences, which Shell farmed into earlier this year, as we work towards a firm well commitment on Selene and Pensacola. Furthermore, our farm out process on the Dewar prospect has generated significant interest which we believe will strengthen with the licensing round behind us."


"This is an exciting time for the Company as we continue to deploy our high-impact exploration-based strategy in a sought-after area."
