The following from the RNS:
"Consequently, the Company believes there is a risk of a material downgrade to estimated reserves attributable to the Lancaster Early Production System, and that there will also be a material downgrade to estimated contingent resources across the West of Shetland portfolio. This assessment does not take into account any production enhancement options for the Lancaster field which are currently under evaluation."
According to the CPR:
The current estimated reserves of 44.5mmboe is based on a 1597m TVDSS OWC.
At the Low case of 1380m TVDSS OWC, the CPR has estimated the reserves to be c. 33 mmboe.
Since production began, working on a 1597m TVDSS case, the reserves would have now dropped to c. 35mboe.
I don't know exactly which value HUR will be working from, but let's assume worst case and say they'll be working from the already reduced reserves following 1 year of production.
At 1380m TVDSS OWC, and following 1 year of production, the reserve estimate will be c. 24mmboe.
The RNS also states that the reserves may be shallower than the ranges envisaged in the 2017 CPR.
So if there is a downgrade, the reserves attributable to the Lancaster EPS will be less than 24mmboe. (This is including additional volumes from the supposed extension of the EPS from the past).
The statement: "any production enhancement options for the Lancaster field"
Could this be the volumes from the extension of the EPS?
If so, current Lancaster EPS reserves following review is likely to be c. 10mmboe.
Thoughts anyone?
