While it is very clear Stellar is the target, I would not discount, Charlie and Indigo to quickly as current value drivers.

Using PMO who are the hardest marker on Stellar. In their half year presentation ( https://www.investis-live.com/premier-oil/5d307a239add6d1100dca1b3/onvd ) they give an expectation, of 150m barrels from Stellar, for their 60%. Which gives 75m barrels for 88es 30%.
In total they see 250m barrels recoverable, from the ~1000m barrels oil in place in the Stellar formations.
To give that some context PMO appeared to present the crude bones of their investment case, an investment case, on which US $23m is risked, will always be rigorously tested for failure, under a minimum return scenario.
In this presentation PMO pretty much only mention Charlie and Indigo as an additional potential, so completely agree Stellar is the prime target.

But to conclude the other targets are not part of the current value case for 88e share price, is not the case for me, I see some real value there. In effect and with hindsight Magluk 1 was drilled in the wrong spot, totally missed Charlie and passed through a very poor zone of Indigo.See this post (https://hotcopper.com.au/posts/40855907/single ) for maps showing, where it missed the productive zones shown by 3D inversion etc, and where Charlie 1 test well, is targeting a much better zone. Looking at the maps Malguk1 passes through the white coloured poor zones while Charlie1 hits some strong green. Indigo is poorer green, but still much better than Magluk1

Subsequent to the above post on 13/10/19, 88e have released the 3d animation video and 2D mapping, showing a good intersect on Charlie, with a good depth of contact within the zone, as it perches over the shelf. Bear in mind Charlie and Indigo have good porosity and are relatively shallow, so should be cheaper to develop and have good natural flow rates.The optimist in me sees a good result from the Charlie zone, while the investor remains aware of the risk.
