Note also that the 2018 CPR did not take into account any of the sucess that Exxon had on the Stabroek block as the data was not available to the competent person. This is why the highest COS for the Cretaceous targets was only 22.4%.
(2018 CPR p17) 'Although recent drilling activity has confirmed the presence of commercial accumulations of hydrocarbons, the data from these discoveries is not yet available. Therefore, due to the paucity of available data, the subject leads have a high level of risk. The database is limited to 3D seismic data and the information from the few βlegacyβ wells drilled in the area and public information.'
Looking at the 2019 CPR we can see that the COS and MMBOE figures for the Cretaceous targets remains the same apart from the KB prospect, which has increased from 243.3 MMBOE at 21% COS to 349.5 MMBOE at 28% COS. The lack of upgrade is because the Stabroek Cretaceous data is still not available to the competent person.
(2019 CPR p20-21) 'Although recent drilling activity has confirmed the presence of commercial accumulations of hydrocarbons, the data from these discoveries is not yet available to the Orinduik partners. Therefore, due to the paucity of available data, the subject leads have a relatively high level of risk...'
The CPR then indicates that more information was available for the Tertiary, which was the subject of this new CPR.
'...although the modeling work done by the partners from the Hammerhead results has mitigated some of the risk in the Tertiary.'
The map on p83 of the 2019 CPR shows that ECO's partners had access to 3D covering the the Tertiary Hammerhead discovery, which I have labelled. I infer that this information combined with the Hammerhead drill result allowed the competent person to sign off on a higher COS for the tertiary targets on Orinduik.

Given the immensely high strike rate in the Cretaceous directly downdip of Orinduik, I think it highly likely they would have also assigned an equally high COS to ECO's Cretacous targets if they'd had access to 3D covering Exxon's Cretaceous discoveries.
In reality, I think the COS for the Cretaceous discoveries is as good as it is for the Tertiary and drilling will prove it.
