Independent Abandonment Assessment of ConocoPhillip's Bayu Undan Well Portfolio

RESL completed a 6-month independent abandonment review of ConocoPhillips Australia's well portfolio at Bauy-Undan. 

The scope of work included an assessment of the abandonment methodologies required to comply with both local regulations and the client’s wish to comply with Oil&GasUK's guidelines for well abandonment. In addition, an alternative assessment was made quantifying likely costs for a rigless approach, in which the required derogations from the local regulation were detailed.  The work covered AACE Class 4 cost estimates for a total of 29 wells: 

- Subsea Wells: 2 producers and 6 suspended exploration wells
- Platform Wells: 21 wells across 2 facilities
