Sorry I am not sure about the decline rates here.

It's a smallish field so they should b able to deplete it in a said timeframe. The missing piece of the puzzle was the actual flowrate from the wells when compared to the pre-flow modeling. Overall they need to flow 55-68 TJ/day to meet their GSA contract over 11 year life.

During the Production test one generally shuts the well for number of hours to buildup pressure & then open it on daybreak to let her rip thro' the flareline (safety reasons). This 'shut-in/open' process is repeated over number of hours & on different Orifice settings. Their contractors keep a minute by minute Graph of pressure vs time on the rig pressure showing the Buildup & any Decline. Using this data they can project the reservoir's behavior over the life of the field.

Noticed the flwrates of 38 to 48 MMcfd are on 1.375" & 1.625" choke settings with minimal sand flow & CO2 and pressure decline.

Their plant capacity is 68 TJ/d, so 2 wells flowing at decent rates should b able to meet the reqd rate in my view. 68 TJ/d is apprx 64 MMcfd & 55 TJ/d is apprx 51 MMcfd flow. Multiply that by 365 days (or factor in 96% efficiency & 4% shut down for routine plant servicing/ maintenance etc). That should take care of 20 to 25 PJ/yr over 11 years. Hope this helps.
