Project Completed So Far

To date, Stuart Wright has reviewed a New Zealand operator's abandonment program and delivered an assessment of the adequacy of the program. The program was assessed against New Zealand regulations, the Operator's abandonment standards, international standards and good oil field abandonment practices. In particular, Stuart Wright provided expert technical opinion on the following 4 questions that were posed by WorkSafe New Zealand to Stuart Wright:

1. Is Operator's proposed permanent abandonment approach of leaving all open hole side-track zones to cross flow fluids and pressures compliant with recognized good practice and international standards?

2. If the answer to Q1 above is no or partial, provide details of where or how they do not comply.

3. Does Stuart Wright believe that there will be any long term integrity issues caused by the proposed original wellbore abandonment method? Giving consideration to:

  • Water bearing zone with sub-normal pressure above reservoir

  • Normally pressured reservoir completed with slotted liner

  • Presence of an impermeable shale layer between water bearing zone and hydrocarbon bearing reservoir

  • Presence of a impermeable shale layer above water bearing zone

4. Has the Operator's proposal to abandon the original wellbore complied with their own barrier and abandonment standards?
