Play models in Quadrants 3, 4, 5, 9 and 10 in Norwegian North Sea
This presenta,on is made to give some few examples of tested and untested play models in the North Sea. No accurate loca,on is given in both stra,graphic nor XY coordinates. Valioso Ltd and its authors is not to be held responsible for any inaccuracies and errors in material presented herein, and therefore not responsible for any ac,ons by any party based on these ideas presented in this presenta,on.

Seismic line A-‐A’ illustra,ng well 9/11-‐1 and down flank poten,al from this well loca,on in open acreage to the SW. Well 9/11-‐1 which is a well with traces of hydrocarbons within it, illustrates that there is a poten,al in this region. The seismic line below illustrates the tectonic elements SW of this well loca,on. A A’
Rela,ve Acous,c Impedance line of same line as above. Blue colour indicate low acous,c Impedance areas, red indicate high acous,c impedance areas. Area B and C indicate stra,graphic intervals with lower AI values which could indicate porous zones. Area B exhibits a on lapping sequence with a central lower AI unit. Area C indicate one of several examples of rela,vely lower AI intervals at this stra,graphic level which could contain higher porous zones with poten,al for HC.

Details from previous slide..
There are iden,fied leads/ prospects at Paleocene sands in the Siri Fairway system, and at Cretaceous Chalk levels, in addi,on to poten,al deeper intervals in Cretaceous and even deeper levels. However the laVer two intervals are not covered in this report. There are iden,fied 19 various leads/ prospects in this area, they range from anomalies to structures and stra,graphic traps.
Many of these leads are in present licensed acreage, however s,ll some are within open acreage and up for grabs.
Lead overview Lead 1 is iden,fied in Block 3/6 within the Palaeocene sands and Chalk levels, see figure below, however the risks associated with the various levels are quite different due to mainly trap integrity. A depth of this lead is around 2000 meters. The lead is associated with salt Diapir, however not dependant upon seal against this. There is also a poten,al for Oligocene sand traps in this area. Source is the main risk for this lead. The lead is assumed to have a volume in place in Paleocene interval of around 70-‐150 x 106 Sm3 oil at Chalk level around 120 x106 Sm3, both cases with associated gas phase.
Lead 2 is iden,fied mainly in Block 4/4 and stretches into Danish sector as well. A well has been drilled on the crest of the SE flank of the lead on the Danish sector. This well had no Paleocene sands. There was oil shows in this well in the Chalk interval. The Chalk was of poor quality in the well loca,on. Paleocene sands are deposited around the rim of the Salt structure which has formed the trap of this lead. It is assumed a stra,graphic trap at this level. Main risk is source and trap integrity due to shallow faults at crest of structure. GRV is approximately 61 x 106 m3.
Lead 3 is located mainly in Block 4/4 with some por,ons in Blocks 10/10 and 4/1. The lead is similar to lead 1, but the salt diaper is shallower at this loca,on. Paleocene is main target with poten,al but very high risk at Chalk level. The lead is at approximately 1700 meters with a GRV of approximately 20 x 106 m3.
Lead 4 Is located in Block 4/2 and is a Paleocene interval lead.
Lead 5 is located in Block 4/2 as well, defined as a Paleocene lead at approximately 1400 meters depth. The trap is a stra,graphic trap within Hermod level sands at around 1300 meters level, associated with a possible DHI.
Lead 6 is located in Block 5/1 and is defined by an anomaly at Oligocene level (Grid Fm?).
Leads 7,8 and 11-‐16 are all defined by anomalies at Oligocene level (Grid Fm?).
Lead 9 is located in Block 10/12 and is defined as a low relief structure at Paleocene level with a approximately 100 x 106 m3 GRV. Source is the main risk for this lead.
Lead 10 is located in Block 10/11 and 10/12 and is defined as a Paleocene level lead at approximately 800 meters depth with a GRV of approximately 1500 x106 m3. Main risk is reservoir distribu,on together with source.
Lead 17 is located in Block 3/3, no informa,on about this lead available at the ,me of wri,ng the report.
Lead 18 is located in Blocks 3/1, 3/2 and 3/5, Oligocene Lowstand Wedge lead, massive lead opportunity with large poten,al. Risks are biodegraded oils and trap integrity. The lead is in excess of 700 km2 and lies in the open acreage of blocks 3/1, 3/2, 3/4 and 3/5. There are found amplitude anomalies, and poten,al direct hydrocarbon indica,ons.
Lead 19 is located in Block 3/5ю
