Part 2.
Porosity: CPR 25%, RNS 45%
Permeability: CPR 1D, RNS 2-5D
Net pay: CPR 65ft(20m), RNS up to 110m since there doesn't appear to be compartmentalisation (NH - please note!)
Gas Expansion Factor or Bg: CPR 140, RNS not stated, but my amateurish calculations for this drilling depth plus 500psi overpressure suggest nearer 300, i.e twice as much gas per m³ than used in the CPR.
Upside: The 295BCF quoted is for Upper Tortonion (TGB-2/-3/-4) only. Data in the September 2021 presentations suggest the whole MOU-fan has up to 1.8TCF including the Mid Tortonian (Lower Hoot). That's using the old porosity & permeability numbers, of course we don't know if those factors are as good for the other formations.
NPV: Couldn't work out how they arrived at the stated value, since not all the assumptions were given, but they didn't include any of the increased possibilities above. Nor did they reduce the capex required as a result of using leased production gear, which would increase the NPV significantly. The £1.465p share price was still based on the February 2022 CPR numbers, which have been called in to question by a number of posters here for being at the conservative end of the scale. NB - I am using polite understatement here, don't want to upset the King.
Gas price: CPR $9/MCF, 2021 average price achieved by SDX was $11.4/MCF. God knows what it will be going forward, but my rough calculation suggests that for each $1/MCF increase above $9, the (old, incorrect) NPV goes up $30M.
So in summary, and please note only in my opinion, every single factor in the RNS is an improvement over the February 2022 CPR, and this will obviously be reflected in a new NPV derived from the next, post-flow test, CPR (Feb 2023?). That's why I'm not at all concerned about the worst case financing scenario of having a $2M placing.
