Hell ! Around Brooks and Medicine Hat they moved every second day. Most of the time they started drilling ahead half an hour after theyfinished cementing the surface casing. Eventually they started going a week a head with a small rig that drilled and set casing on the surface hole. At least then, when the damned hole blew out on them, the surface casing was well cemented in and the BOP stopped the drill string from ending up in Saskatchewan.
Where the big deep hole ones sat in one spot for 6
South of Calgary was bad hole counrty, and they used to take 6 or seven months to do a 12,000 ft hole. If they put any weight on the string it would take off down the first weak spot in the formation and you'd have no idea where it would end up. The rig crews loved it because the bits lasted for ever with no weight on them and they'd only trip the hole about once a week.
