sec.25 Cutting samples

A holder of a GHG tenure must, for each GHG well drilled under the tenure, keep the cutting samples of the geological formations penetrated by the drill for each interval mentioned in subsection (2) . For subsection (1) , the intervals are— each 10m interval, or part of a 10m interval, from the surface to as close as practicable to the top of the geological formation nearest to the surface that is likely to contain a GHG storage reservoir; and each 3m interval, or part of a 3m interval, from as close as practicable to the top of the geological formation mentioned in paragraph (a) to the bottom of the well. The part of the sample given to the chief executive under section 259 (1) of the Act must— be between 250g and 500g in weight; and be washed and dried; and be given in a labelled container suitable for long-term storage and handling that states— the identifying name of the GHG well from which the sample was taken; and the depth in metres of the top and bottom of the interval from which the sample was taken. In this section— cutting sample means a sample of the cuttings produced by the drilling of the well.

• (a) each 10m interval, or part of a 10m interval, from the surface to as close as practicable to the top of the geological formation nearest to the surface that is likely to contain a GHG storage reservoir; and
• (b) each 3m interval, or part of a 3m interval, from as close as practicable to the top of the geological formation mentioned in paragraph (a) to the bottom of the well.
• (a) be between 250g and 500g in weight; and
• (b) be washed and dried; and
• (c) be given in a labelled container suitable for long-term storage and handling that states— (i) the identifying name of the GHG well from which the sample was taken; and (ii) the depth in metres of the top and bottom of the interval from which the sample was taken.
