maybe you are right sir.
but from what i understand, their horizontally drilling is not for coring exploration but for deepwell. they drill into the side of the mountain and place a steel casing there in order to get water and prevent collapse in the long run since water will come out in big volume and in greater pressure from the aquifer. its not only to get a core sample but to provide deepwell water to low yield water areas. if it is for deepwell, they need to place a bigger steel casing there like 4 inches up to 24 inches or more. that's maybe the reason why they only drill up to 400 feet.
if it is for coring soil samples with no idea of reaming to a bigger hole and placing a bigger steel casing later for the big volume of water to come out from the aquifer coming from the side of the mountain, then you only drill a very small pilot hole and no reaming.
