It's not bad news, they just want to reprocess the data so that next time maybe they don't drill another dry hole. I see nothing in this news release that says dump.
The fact that they'll be much more likely to drill their next well in a productive area due to the utilization of cutting edge data analysis and more homework is bad news to you? I don't get your point? Why would this cause a selloff?
PS) It may be time for you to pick a new screen name. The current one seems to be a bad fit.
