We were tasked to provide geophysical, 2D seismic and geotechnical assessment of the site in preparation for the arrival of the Noble Tom Prosser Jack-up MODU.
The well was drilled conventionally using a 30 x 13 3/8 x 9 5/8 x 7” well design to a total depth of 1,500m. Conventional cores were taken through the 8 1/2” hole section with wireline logs taken over both the 12 1/4” and 8 1/2” hole sections. The 7” liner was perforated to provide the conduit for injectivity testing before the well was abandoned to meet regulatory requirements.
AGR assembled a highly experienced, multi-disciplined team with expertise in niche areas to manage all aspects of the Well Management project, ranging from Regulatory submissions, Contracting, Stakeholder Engagement and Engineering. A small and focused team provided the conduit for a streamlined operation, allowing for flexibility and rapid response to the challenges encountered with minimal impact to the project schedule and budget.
- All contracts with the exception of the rig, negotiated, held and managed by AGR following a comprehensive tendering process audited by the Government. The highly experienced AGR contracting team generated $A / 7MM in savings to the client
- All regulatory submissions produced in house, with no delays to any of the Geophysical & seismic, Geotechnical or Drilling campaigns
- All campaign activities successfully executed with final costs falling below AFE, a great result for the client
- Logistical challenges overcome with no impact to the critical path of operations. Equipment mobilised from 13 different countries
- Appraisal objectives successfully met with 89 meters of core taken, an extensive logging campaign and over 9,000 barrels of drill water injected during the injectivity test.
- The Geophysical, Geotechnical and drilling campaigns were successfully executed with no harm to the environment.
- The tailored stakeholder engagement strategy was implemented and contributed positively to the acceptance of all regulatory approvals on a comfortable timeline.
- The leveraging of AGR’s experience generated substantial savings to the client and minimised the impact of the challenges that arose during operations.
- The well was successfully appraised and abandoned using materials suitable for future CO2 storage at the site.
