Part 2.
It has been necessary in Moruga West to drill many wells, covering an area of around one hectare (2.5 acres) each. This isn't as bad as it might appear, one MW well producing a total of 455,000 Bbl just using old style rod pumping, with an average cumulative total of 141,000 Bbl from each of the top 50 wells. To date, only 18% of total estimated oil in place has been recovered from a field that has been producing since 1955, with an expected EUR (Estimated Ultimate Recovery) of 30%. Many of the MW wells were drilled 50 – 70 years ago, using outdated subsurface evaluation and drilling techniques, but some compartments have already produced 38% recovery.
The ITR for C-M has used also a 30% EUR, which is low compared to most newly drilled fields. PRD has the benefit of modern subsurface methods to identify reservoirs, more sophisticated drilling and completion techniques, dewaxing technology, plus experience of CO2 EOR to increase the recovery rates. C-M oil also has dissolved gas at 700 CF per Bbl, this is unlikely to be commercial, but is certainly available for re-injection to help maintain oil production pressure. We also saw this week that TXP have employed horizontal drilling to increase borehole / reservoir contact area, a technique that may be transferable to C-M.
It is apparent that the existing wells on C-M were sub-optimally sited, poorly drilled and not fully evaluated (RD-1 dates from 1955). The ITR also notes incomplete logging, giving additional potential from missed horizons in the historic C-M wells. The use of NuTech logging may reveal substantial additional gas not taken into account in the ITR volumetric calculations.
In short, I see the Cory-Moruga ITR projections as being conservative, that this is already a more valuable asset than many realise, and agree with GRH that it has an excellent chance of surprising to the upside. We will have our first real insights very soon – Snowcap-1 re-entry and workover in March, and Snowcap-3 due to start drilling in April / May, at no cost to PRD. Snowcap-4 perhaps June – July. The deep value in these is not the oil production per se, but in the detailed re-evaluation and de-risking of the whole block.
Hard numbers from the ITR, opinions my own.
