Rodinia Spuds Second Exploratory Well Offshore Australia

Rodinia has spudded its second exploratory well, Kutjara-1, in the Officer Basin, South Australia.


  • The Kutjara-1 well commenced drilling on November 2, 2011 with the objective of appraising the Kutjara structure
  • The well is targeting multiple prospective Neoproterozoic reservoirs
  • The well's target depth is 2,668 meters and it is expected to take approximately eight weeks to drill to total depth ("TD")
  • Kutjara-1 is the second well in Rodinia's Officer Basin exploration program

Kutjara-1 Well

Kutjara-1 is located in the west central portion of PEL 253 approximately 45 kilometers southeast of Rodinia's first well, Mulyawara-1. Rodinia has an 80% working interest in PEL 253 and is the operator. The Kutjara structure has been well defined by recently acquired infill 2D seismic. The structure is large (approximately 12 km by 3 km), defined by six seismic lines and has multiple potential reservoirs. It is also offset by several other large closed structures that could be followed up on if this well is successful.

Based on lessons learned and information gathered by Rodinia at Mulyawara-1, Kutjara-1 will be drilled using the following modified drilling techniques in order to improve drilling efficiencies and lower costs:

  • Drilling a smaller diameter hole throughout
  • Dropping several casing strings from the original well design
  • Eliminating the air pack/hammer drill assembly, which will reduce damage to the bottom hole assembly and related twist offs, fishing runs and tripping time
  • Achieving higher average rates of penetration by using PDC bits rather than tricone bits

The primary objective of Rodinia's current capital program is to appraise the potential of the large structures currently identified on its lands in the Officer Basin, South Australia. The Mulyawara-1 well substantially added to Rodinia's knowledge of the geologic and hydrocarbon potential of the Officer Basin. Rodinia will continue to expand its understanding of the extent and reservoir potential of the Neoproterozoic formations with Kutjara-1. However, Kutjara-1 is a high-risk exploration well, which is yet to be proven.

Paul Bennett, Chief Executive Officer and President, commented, "We are excited to spud Kutjara-1, the second well in our current Officer Basin exploration program. Our immediate objective with this well is to appraise several potential reservoirs in this structure, one of several large prospective structures that we have identified on our lands."
