40—Well completion reports (amended for Geothermal)

  1. A licensee who undertakes any drilling must furnish to the Minister, within 6 months after rig release, a well completion report in accordance with the requirements of these regulations.
    Administrative penalty. 
  2. A well completion report must include—
    a) the name and number of wells; and

    b) a summary page or pages, located at the beginning of the report, which set out in a concise form basic information relating to the well found in the report; and

    c) a plan that shows—
    (i) the location of the well relative to a horizontal control point and a bench mark established not more than 200 metres from the site of the well; and
    (ii) the latitude and longitude of the well in GDA 94 values, computed within the accuracy levels approved by the Minister;and
    (iii) any permanent reference marks established in accordance with these regulations; and
    (iv) the direction of true north; and
    (v) any other well and all roads, access tracks, public utilities or substantial buildings or other structures within 300 metres of the site of the well, and any significant topographical, environmental or cultural features; and
    (vi) where applicable, the boundaries and legal description of the section of the land within which the well is situated; and

    d) the name of any drilling contractor; and

    e) the spud date, the date of rig release, and then total depth drilled (to drillers and loggers depths, in metres); and

    f) a summary of the litholigies encountered during the drilling, and a summary of the geological formations taken to have been encountered during drilling; and

    g) a composite log, formulated to a scale comparable with the wireline logs used in connection with the drilling, that includes the following:
    (i) the bit record
    (ii) the penetration rate; and (for wells with a depth > 500 metres)
    (iii) the casing record;
    (iv) a lithological summary;
    (v) geological formation tops;
    (vi) representative open hole and cased hole logs; (temperature and GR log)
    (vii) sidewall core points;
    (viii) palaeontological analysis results;
    (ix) hydrocarbon shows; (not applicable)
    (x) the drillstem test intervals and results; (flow test)
    (xi) core intervals and recoveries;
    (xii) the log analysis result; and

    h) core and sidewall sample descriptions, and an analysis of these (including thermal conductivity); and

    i) relevant petrographic descriptions; and 

    j) the palaeontological analysis results and interpretation; and

    k) the formation test reports; charts and interpretation; and

    l) log interpretations; and

    m) details of hole sizes, casings and cementing that has been undertaken; and

    n) details of well completion or abandonment; and

    o) a velocity survey; and (for wells with a depth > 500 metres)

    p) a geophysical interpretation of the target structure at relevant horizons (not applicable)

  3. For the purposes of subregulation (2), all depth references for a well must be in metres.

  4. A copy of a report under this regulation will be available for public inspection after the expiration of 2 years from the date of rig release.
