Ann: Wagina Gas Discovery, page-437

Ajgeo,
I was intrigued and went back through STX announcements.

First it appears that you obtained your CO2 content from 30/08/17 Klebb Technical Success announcement where the gas content was between 32 and 44%.

It appears that they have not published measured CO2 content from Jaws

In their 2nd July 18 announcement they state:

Gas compositional analysis has unfortunately yielded data that is unreliable and inconclusive. Definedparameters are not able to be drawn from the coring program due to quantity, quality and testingconditions of the cores recovered. During testing the samples showed air contamination with unusuallyhigh Nitrogen levels and presence of Oxygen. Gas composition remains an undefined parameter of Strike’sresource with plans to narrow the expected outcomes during the upcoming production testing of the Jaws1 wells.

However in their 19/07/18 Quarterly report they state:

 Numerous conclusive tests and analysesover time of both Klebb production and LeChiffre cores have shown ~70% methane.Composition analysis from the coresobtained from Jaws suffered from aircontamination and consequently the resultsof the test were declared invalid by Strike’sthird-party experts.

 Based on isotherm data, full scaleproduction from Jaws may show lower CO2levels than Strike’s estimates due topreferential desorption.

It appears that the information I received (25% CO2) was based on the last dot point

I hope I haven’t missed anything
