Note:
The 2022 produced volume of 1.09 mmstb accounts for 61.6% of the overall 2P decrease in 2022 compared to 2021.
Revisions:
- Onshore: FZ-2 +0.22 mmstb and WD-14 +0.26 mmstb due to Economic Limit Testing. Onshore sub-licences decrease (-0.61 mmstb) due to uneconomic infills.
- East coast: Reduced base performance due to decreased well performance from key producers in Trintes (-0.78 mmstb). Reduced RCP 2P from 2021 to 2022 mainly due to reduced RCP count (-0.07 mmstb). Reclassification of three conventional infill wells from the Echo FDP back to Trintes development 2P reserves. +0.72 mmstb.
- West cost: Reactivation of ABM-151 in March 2023 and revised IP of 80 bopd; +0.15 mmstb. Reallocation of infill wells from 2P to 2C category (-0.20 mmstb). PGB base decreased -0.37 mmstb.

Note (*):
Onshore:
• Recently concluded 3D seismic mapping work across WD-5/6, WD-2, PS-4 assets has redefined the subsurface structure/model resulting in the addition of 2C resources +4.80 mmstb in Year End 2022.
East Coast:
• Year End 2021 most likely case of 12-well development inclusive of three Trintes infills re-categorised at Year End 2022 as part of Trintes development 2P rather than as Echo 2C (-3.58 mmstb).
West Coast:
• Reallocation of infill wells from 2P to 2C category across West Coast +0.44 mmstb
