Part 2. Valuation of 2B
There is a wide range of estimates for the size of 2B. Some of the estimates of oil resource appear to confuse oil initially in place with recoverable oil, and the 3 drilled prospects with the whole 2B block. For today, I will stick with the CPR P50 volume, since this provides a well researched base, onto which you can overlay your own more optimistic or pessimistic factors.
The Strand Hanson March 2022 CPR provides a detailed estimate of oil volume. This is no easy task, and Section 5, Probabilistic Resource Analysis, summarises how they have gone about it. Have a strong coffee before reading. The 2B input parameters are on p.112, and the conclusions on p.117. They have examined only the 3 prospects just drilled – Gazania, Namaqualand & Pelargonium – and come up with an ECO 50% attributable P50 (best estimate) of 246 MMBbl, plus 37 BCF of gas. Note that the whole of 2B – including the Northern Graben & the Eastern Prospects – could double this figure. The Billion Bbl number that has been hoped for is possibly a result of SH using a 25% recovery factor: 246 x 4, but unrecoverable oil by definition does not have an economic value.
With the likely continued high oil price, it seems reasonable, but possibly conservative, to assume an in-ground price somewhere between $5 – 10 per Bbl for a Contingent Resource, shallow water, near shore environment, with a supportive, low-tax jurisdiction such as the RSA. In a recent interview, Gil suggested $8 per Bbl. How have people come up with this number?
In the Align Research note of January 2022, they suggested a value of $5.98 per Bbl – from p.31 “analysis was undertaken for a potential project in South Africa that took account of a royalty rate of 5% and income tax rate of 28%, together with highly favourable treatment of costs which allows 200% of exploration and 150% of capex to be deducted. An NPV(12) per barrel figure of US$5.98 was determined, using the same flat oil price [Brent $70], which does highlight that South Africa has some of the best fiscal terms on that continent.” NB Align use a discount rate of 12%, which reflects the higher risk rate applied to African projects, and a long term oil price of $70.
So let's use the above price and volume data – oil only, no account taken of any gas finds.
ECO has 344M shares in issue, today $1 gets you around £0.87p.
So for every recoverable 100 MMBbl, that is worth £87M for each $1 per Bbl value in-ground, or roughly 25p per share. For the suggested Align ~$6 per Bbl, that takes it to £1.52p per share.
For the CPR's P50 246 MMBbl, at $6 per Bbl, it moves up to £3.73p per share.
You get the picture, I'll let you tempt fate by calculating the effect of a higher volume and/or price!
