Ann: GGP: Oil encountered in Acosta Well , page-5

Sentia

Thank you for forwarding these concerns as I imagine that you may not be alone.

1. The side wall cores identified the presence of Oil in the Camerina and the Miogyp intervals.

2. The productive intervals are called “pay”, the distance between the top of the interval and the bottom of the interval is usually referred to “gross pay”, not the entire interval is necessarily productive, so the potentially non productive sections are discounted and hence the term “net pay”.

3. The cores reflected oil in the results. It is difficult to determine the level of gas at this point, time will tell.

The results are positive, the productivity of the well and how it will translate to reserves for the structure will be contingent on productive testing and other resevoir analysis.

Regards

Mark
