2. Remarks to note during drilling
A record of the driller’s observations on progress of drilling, rate of penetration, speed and uniformity of rotation of bit, action of the drill rig such as jerky, smooth, rough, steady etc.
Length of each core run and the length, percentage or both of core recovered along with location and cause of core loss (core drilling only).
Any changes in the character of the drilling water or mud, and in case the drilling water disappears, the elevation or depth where this happened.
The driller’s interpretation and description of the nature of the formation(s) encountered in the drilling.
Location and nature of cavities, seams, cracks, whether filled or open, soft or fractured rock and any other relevant information in connection with the purpose of the exploratory drilling.
