Are we there yet?19 Apr 2022 06:07
Part 1.
Here's my take on where we are, and where we should be heading. You may not agree, that is your prerogative, and in any case you should formulate your own views before investing.
This time last year.
CPR gives 2U/P50 (unrisked best estimate Prospective Resource) of 138 Bcf He, assuming 4% He. Risked equivalent is 14 Bcf. Risk factors relate to source and migration of He, presence of reservoir rocks, structural traps, and adequate seal, all unknown factors at that time. This is Rukwa only, no Balangida, no Eyasi. Crazy President John Magafuli had just died. Market cap £48M.
Now.
Source and migration of He confirmed - 2.2% at 70m in Upper Lake Beds, detected in Red Sandstones at 552-561m, detected in 5 separate depths in Karoo Sandstones, plus MSSI data shows extensive surface seepage related to fault-delineated prospects. Reservoir rocks of 15 - 20% porosity confirmed by drilling, suitability confirmed by QEMSCAN. Seal rocks up to 130m thick confirmed by drilling. Additional deep structural traps identified by multiple geophysical methods, ERT to detect traps shallower than 200m (seismic only works well below 200m). Integrated prospect definition data available imminently. The only reason a discovery has not been declared is due to engineering issues - underpowered drill rig, too narrow a borehole- nothing to do with the geology. The HE1 team has been expanded to include geophysicists specialising in O & G, drilling specialists, and a NED with gas commercialisaton expertise. New President Samia Suluhu Hassan has demonstrated a competent, businesslike and resource-friendly approach to running Tanzania. Market cap £71M.
Later this year.
Rukwa basin is already essentially derisked, so the likely resource as per the original CPR is a lot closer to the 138 Bcf rather than the original risked 14 Bcf. CPR assumed 4% He, expect it to be double this - so maybe the resource should be 200+ Bcf. Several new, larger prospects have been identified (details very soon), with thicker seals, so perhaps a new CPR of 300-500 Bcf, and this will move from Prospective to Contingent Resource upon successful discovery - discovery merely being the recovery of a quantified concentration of He from a previously identified prospect. Finally, flow testing may result in a declaration of commerciality and statement of Reserves - upon which point all hell will break loose (figuratively, not literally, we're not drilling that deep!)
