I'm not sure exactly what they mean by 'apparently unconsolidated sandstone'. If that's loose sand a frac would be a pointless exercise. According to my reading some sands are so loose they actually inject a resin into the reservoir to partially bind the sand grains together to prevent rapid erosion of the near-bore reservoir into the well, ie the opposite of what a frac is trying to achieve. Question is, what sort of reservoir do they have here?
