How to read a RNS - lesson 227 Nov 2024 13:40

While preparing the hole for wireline logging, the rig encountered caving with the Mowry shale from ~2,100 feet onwards which compromised the stability of the wellbore. Stability issues in the Mowry shale had not been seen in any surrounding wellbores, including Hillison #1.

In the Charles formation was perforated at a number of intervals over a 145ft section (5,010ft - 5,025ft, 4,954ft - 4,960ft, 4,935ft - 4,947ft and 4,855ft - 4,880ft). While gas did not flow to surface during this initial test, downhole pressure monitoring and drilling data indicate a promising reservoir. High mud losses during drilling suggest that formation damage may have temporarily inhibited permeability. Helix remains confident in the Charles formation's potential and plans to revisit this horizon to unlock its full value.
NB Quite a lot of perforations and still no flow
Today
The Company is therefore keen to move rapidly on to testing the Charles formation which demonstrated the highest helium anomalies identified in Clink #1 with up to 672ppm He in drilling mud, excellent reservoir properties and strong gas effect in wireline logging. The Company will mobilise equipment to acidise the limestone reservoir with HCl to clear mud blockages and stimulate flow. Stimulated flow testing and appraisal will commence as soon as equipment and crew are available.
NB if had string gas "effect" why nothing in RNS to say so? Or reading between the lines it is all on the word "effect" hmmm
Of course they are "keen" to move rapidly on now! They weren't so keen before were they lol?
They are assuming that it is mud blockage, but they won't actually know until they clear it and try and test again. Could quite easily be a shale problem again.
NB as soon as crew and equipment are available hmmmm time and money. What with Hydrogen experts having to be drafted in for Flathead you sure you going to have enough cash? Probably, IF Rudyard doesn't have problems. But very much doubt it for anything after.
