UK oil and gasoline firm Deltic Energy, previously often known as Cluff Natural Resources, has recognized three prospects inside its Southern North Sea licence and is looking for companions to assist de-risk them forward of drilling.
Deltic mentioned on Monday that it had accomplished an in depth technical analysis of its key Southern North Sea licence P2428, which accommodates the Cupertino Prospect.
Licence P2428 was awarded to the corporate within the UK’s 30th Offshore Licensing Round with an efficient date of 1 October 2018.
Preliminary work accomplished by Deltic to assist the applying course of recognized the potential for important prospectivity within the deeper Carboniferous part.
Deltic additionally recognised the constraints of the pre-existing legacy 2D seismic datasets and the potential uplift in knowledge high quality which may very well be achieved by way of trendy reprocessing workflows.
Throughout 2019, the Deltic technical crew labored carefully with its chosen contractors to reprocess 852 line kilometres of classic 2D knowledge utilizing a contemporary Pre-stack Depth Migration (PSDM) workflow, which resulted in a major uplift in knowledge high quality.
Accprding to Deltic, the technical work accomplished because the reprocessed seismic knowledge was delivered has not solely matured the Cupertino Prospect however has additionally recognized important beforehand unrecognised prospectivity within the Rotliegend northern feather edge play in addition to the rising Zechstein Reef play.
The licenced space additionally accommodates the depleted and decommissioned Forbes Gas discipline which produced gasoline from the Triassic Bunter Sandstone between 1985 and 1995, and which has been beforehand evaluated for its gasoline storage potential and its doable suitability for CO2 storage sooner or later.
Deltic recognized three prospects
Three geographical prospects have been recognized on the licence, which the corporate believes are of appropriate scale for future commercialisation.
Graham Swindells, CEO of Deltic, commented: “With mixed P50 recoverable gasoline sources in extra of 900 BCF or the equal to in extra of 150 million barrels of oil, these prospects are clearly materials when it comes to their total scale each individually and collectively.
“In addition to our Selene and Pensacola prospects with Shell, these Cupertino stacked prospects, coupled with our lately re-acquired Cadence prospect, adopted by our different latest licence awards, proceed to ship our said technique of growing a conveyor belt of exploration drilling alternatives of fabric scale.
“Our consideration will now flip to attracting the very best accomplice to assist us take these alternatives ahead in the direction of drilling”.
The Cupertino Prospect is a Four-way dip closed intra-Carboniferous prospect within the Scremerston Formation which is a confirmed producing reservoir on the Breagh Gas Field and on the Crosgan Discovery situated 40 kilometres to the West.
The prospect is mapped on numerous vintages of legacy 2D knowledge and covers an space of roughly 68 km2 with the structural crest at roughly three,500m TVDSS and a possible hydrocarbon column peak of 220 metres.
Based on the work accomplished up to now, Deltic has estimated P50 GIIP for the Cupertino prospect at 705 BCF with a P90 to P10 vary of 258 BCF to 1,615 BCF. The firm has based mostly its restoration components on the restricted knowledge obtainable from analogous fields and would count on these recoverable useful resource numbers to be additional refined as extra drilling knowledge turns into obtainable.
The bigger prospect space is split into numerous fault blocks and could be significantly better resolved with the good thing about new 3D seismic which the corporate believes could be required to assist a nicely funding resolution sooner or later.
Further intra-Carboniferous prospectivity within the deeper Fell Sandstone Formation, which was recognised on the time of software,…
