ngms27,
Firstly,
" water cut is anticipated to increase quickly after breakthrough due to the high permeability of the fractures and may result in production rates being curtailed or potentially a well watering out completely."
This is unlikely. Sure at the time of CPR this was plausible. But following the recent pressure/production data (CMD 2020), indicate that the reservoir is connected well and therefore has a huge volume. I don't expect watercut to increase that quickly as a result - But that's not to say that the OWC is catching up to well 7z and soon to 6 (therefore the watercut will increase, but not quite exponentially).
Secondly, regarding the recoverable oil:
For the Lancaster EPS, the CPR2017 states that at the structual closure (1380m TVDSS), 1P reserves are 28.1mmboe. This is over the 6 year period of the EPS.
In 2019, 3.2mmboe of oil was produced. Assuming 15k bopd average to the end of this year, we can expect 5.5mmboe being produced in 2020.
With the above assumption for 2020, we can say that in 1.5 years the EPS will have produced 8.7mmboe.
Going forwards to 2021, at the current rates of increasing water cuts (and only production from 6 and 7z), i estimate production to be c. 12-13k average.
In 2021, I'm expecting Hurricane to produce 4.5m barrels.
Going forwards from 2022 to 2025 (again above assumptions), I think it's safe to assume circa 6-8k bopd on average.
That would meant that for 2022-2025, production will be 7.6m barrels.
In total, circa. 21mmboe would be produced with the EPS. That's a 25% reduction in current proven reserves.
Currently, the wells are economical to run until 7k bopd (or 8k if you want to include downtime). Aoka Mizu is economcial to run up to 74% watercut total, or say c. 70% on well 6 or c.85% on well 7z.
I think majority of this is priced in with the reserve downgrade (up to 25%).
Slift.
