sec.28 Daily drilling report

The holder of a coal or oil shale mining lease must keep a report (a daily drilling report ) for each day on which drilling of a CSG well is carried out under the lease. The holder must lodge a copy of each daily drilling report at the same time the holder lodges the CSG well completion report under section 29 for the well. Also, if the chief executive gives the holder a notice requiring the holder to lodge a copy of a daily drilling report, the holder must lodge the copy within 10 business days after the notice is given. A daily drilling report for drilling of a CSG well carried out under a coal or oil shale mining lease must contain the following about the drilling carried out on the day to which the report relates— the number of the lease; the identifying name of the CSG well; the name of the holder of the lease; the type of drilling rig used; a summary of the drilling operations carried out; the depth in metres of the CSG well at the end of the day’s drilling; the size and type of drill bits used; the drilling fluids and additives used; the size and depth in metres of any casing inserted in the CSG well; the depth in metres of the top and bottom of each cemented interval in the CSG well; the results of any deviation surveys carried out in the CSG well; a description of any drill stem tests or other tests carried out in the CSG well; the depth in metres of the top and bottom of each hydrocarbon show interval in the CSG well and the type and description of any surface observations of each interval; the type of any perforations in the CSG well, the depth in metres of the top and bottom of each perforated interval and the perforation spacing in metres; details of any stimulation carried out; details of any squeeze cementing or cement plugging carried out; a description of any cores or cutting samples taken; any other data or information required under the practice direction. In this section— deviation survey means a survey of the path of a CSG well that measures its direction in 3 dimensions. proppant means a solid material used to keep an induced hydraulic fracture open during, or after, stimulation of a natural underground reservoir. sand, treated sand and manufactured ceramic materials stimulation means a technique used to increase the permeability of a natural underground reservoir, including, for example, hydraulic fracturing, cavitation, fracture acidising and treatments using a proppant.
