    Hi huaneng,
    Thanks for your engineering insights - much appreciated. Thinking out loud, in my view the Toolachee Formation in both Odin-1 and Vali-2 will hopefully not require fraccing for the following reasons;
    1. Whilst we have assigned a porosity cut-off of 8% to define the lower end of net pay, (yes, we do not know what Sw cutoff was used), it is possible that the majority of the 37metres of net gas pay in Odin-1 and 24mteres of net gas pay in Vali-2 is greater than 8% as can be seen on the plot below. I hope so.......
    2. MDT samples were obtained from the Toolachee in both wells demonstrating that gas flowed unassisted (unstimulated) into the tool chamber.
    3. In the Vali-2 announcement, the JVP commented, "The wireline logging and MDT results indicate that the Toolachee reservoir may flow without the need for well stimulation".

    Just my thoughts, and we geo's tend to be more optimistic than our engineering colleagues . So we have an good balance of optimism here.
