Sasha explains why we core rock.

On August 4th, the Boy Scouts visited with a full guided tour of the core recovery and core handling process. Sasha, Joseph, and Alan divide them into groups for an up close look core recovery as the drillers bring up a run, and at core processing once its on deck. They also hear about geothermal energy and why its important. On August 7th, The PQ drill string twisted off at 140 meters below surface (inside the casing), leaving the drill bit stuck on the bottom with the weight of 305 meters of drill rod on top of it. The weight prevented the overshot tool from freeing the inner core barrel of the alien tool. To make matters worse, the overshot release tool becomes stuck on the broken edge at 140 meters. A CCTV video crew is called in to view the situation downhole and the overshot release is finally freed from edge. After many calls and much consultation, the overshot is welded to the end of an HQ drill rod, which is sent down to grab the inner core barrel and free it from the stuck bit. Success!! This past weekend, the core barrel got stuck once again.. Collapsed hole? Infiltration of sands? We are working to remedy this situation! We are still in lake sediments, although in the last recovered core barrel, the seds were coarsening.. Expect to be in basalt pretty soon!
