Potential Issues with Marti-5's Logging and Testing

Hi All,

Just posting a summary of my thoughts on issues that may have occurred with Marti-5's wireline logging and the small amount of testing they did.

In the ASX 7/2/22 release, the comment "and there have been significant oil shows present throughout on the shale shakers" confirmed to me what Peter Stickland mentioned in the GOC 2017 Presentation he gave (below), where he used the term "mistreatment of reservoir" in relation to the drilling of Marti-5 through the Lower Sheet's "oil zone". IMO, a possibility exists that the wireline logging and testing results may have been compromised by the very likely use of over balanced drilling and the length of time the reservoir was left open. Thus, if the current drilling practises had been able to be used (significant improvement since 1988 when Marti-5 was drilled) the reservoir section in Marti-5 may also have resulted in far stronger oil shows being recorded and potentially better reservoir interpreted from logs. A bit more evidence for further de-risking of the Lower Sheet's reservoir potential in this area.

Obviously, all IMO - and no doubt people will have different views - but may help some posters further understand the Lower Sheet's potential in this area. Slide 7 is just an Invasion Zone mock-up I made for a friend a few years ago - only very general.
