You make a good point, which I missed in my recent post. Shame on me for not making my comment more balanced.   I have pointed out in a previous posting that the need to find more oil increases the risk of investing in CZE and   4.2 is quite a low number. However,  they have made significant improvements in the last two years.  They have a much larger exploration potential than what they have proved and we shall have to wait for the updated reserve report to see how they are progressing with this issue.
