sec.49 Cutting samples

Each cutting sample of geological formations taken as follows must be kept— when the formations are penetrated making a petroleum well under a petroleum tenure; at each interval stated in subsection (2) . For subsection (1) (b) , the intervals are— for a petroleum well other than a development well—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 natural underground 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. However, subsection (1) applies to a cutting sample taken when making a petroleum well solely for coal seam gas exploration or production only if, before the well was made, the chief executive gave the tenure holder notice that the sample must be kept. The part of the sample lodged under the 2004 Act , section 548 (1) or the 1923 Act , section 76B (1) must be— at least 250g, but not more than 500g; and washed and dried; and in a container that is suitable for long-term storage and handling, and is labelled with— the identifying name of the 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 making the well.

(sec.49-ssec.2) For subsection (1) (b) , the intervals are— for a petroleum well other than a development well—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 natural underground 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. (sec.49-ssec.3) However, subsection (1) applies to a cutting sample taken when making a petroleum well solely for coal seam gas exploration or production only if, before the well was made, the chief executive gave the tenure holder notice that the sample must be kept. (sec.49-ssec.4) The part of the sample lodged under the 2004 Act , section 548 (1) or the 1923 Act , section 76B (1) must be— at least 250g, but not more than 500g; and washed and dried; and in a container that is suitable for long-term storage and handling, and is labelled with— the identifying name of the 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. (sec.49-ssec.5) In this section— cutting sample means a sample of the cuttings produced making the well.
