Well completion and other company reports

Well completion reports are now available to be download free.

FREE downloadable ZIP files are available through SARIG. For more information visit our Well Completion Reports page.

Department of State Development, Energy Resources Division has a library of hardcopy well completion reports of all petroleum and geothermal wells drilled in South Australia, of which there are about 2600. To date, all well completion reports and related technical reports have been scanned, or are now being submitted by explorers in digital format. All well completion reports are available on CD, DVD, Removable hard drive or as FREE downloadable ZIP files through SARIG.

The formats of the scanned reports are as follows — the text of a report is in Adobe PDF format, including bookmarking for ease of navigation through the digital document. Larger plans and logs are captured as either TIFF or JPEG (colour) format and linked to the bookmarked document. These large images have not been embedded in the PDF to give companies more flexibility, including plotting or viewing the images in other software packages or the UNIX environment. Scanned well completion reports in this format can be found on recent data and acreage release CDs and DVDs.

Digital well logs and well log displays (paper prints)

This digital well log database, includes field and edit tapes for open hole logs, measurement while drilling and cased hole logs, as well as higher resolution data including dipmeter, formation microscanner, array sonic, cement bond log, segmented bond tool and vertical seismic profile. Basic log data continues to be archived to CD and DVD, exceeding 65 GB to date. Digital data are available as basic validated data as originally supplied (EDIT or FIELD processing) or data digitised from an analogue source.

All data are sold in the format that was originally supplied. Pre-1999 data are available in LIS format only; post 1999 data are predominantly DLIS format.

All data orders now come with scanned images of the paper prints. Recent log displays may be in PDS (Schlumberger), META (Baker Atlas), TIFF or PDF formats.

The cost of basic log data is derived from the cost of transfer — eg a special CD containing well logs in LIS format for over 350 South Australian wells (mainly Cooper–Eromanga) costs A$100. Free quotes are provided for specialised orders.

Bundled packages

Energy Resources Division are currently offering all open file well completion reports, wireline logs, log displays and a copy of PEPS-SA lite on a removable hard disk for A$2000.
The portable hard disk is provided free but with a caveat emptor — data is provided at cost of transfer but recipient must take responsibility to archive/backup the data in some manner of form. Portable disks are transport mediums (data can be deleted off them).

Core photos

Energy Resources Division has scanned all petroleum core photographs and 3360 full size digital images (~1500 pixels by 1000 pixels by 256 colours) have been captured.

Thin sections

Energy Resources Division is the custodian of over 6000 thin sections, prepared over the last 20 years for various basin studies. All thin sections have been catalogued in the PEPS database and are available for loan. Over 5500 sections have been scanned in normal and polarised light using specialised software and a scanner attached to a petrological microscope. These digital thin section images have been compiled into a searchable database and are available on a DVD as a comprehensive atlas of key reservoirs and seals from South Australia’s petroleum prospective basins.

The system involves a petrographic microscope linked to a computer with a thin section digital image processing program that offers special application modules such as high resolution image archiving and measurement of grain and pore space sizes. The program can easily export data to Microsoft Windows applications such as Excel. This has already been used by the Department of State Development (previously DMITRE) for a study of carbonate reservoirs in the Stansbury Basin, compilation of the Warburton Basin Atlas and the Cooper–Eromanga secondary migration study.
