BAKU, Azerbaijan, Jan.6. Dedicated carbon capture and storage (CCS) appraisal wells are expected to increase in 2023, as companies assess acreage picked up in recent license rounds in Australia, Norway and UK, Trend reports with reference to Wood Mackenzie.
“These wells along with new/reprocessed seismic data may allow a cost-effective way to bridge the data gap and increase the speed of aquifer project announcements,” WoodMac said in its latest report.
The company analysts note that despite the ample CO2 storage capacity identified to date, additional investment will be required to move prospective sites to development.
“Much of the global prospective storage capacity is under-appraised and only a small fraction is associated with FID projects. Appraisal of depleted reservoirs will dominate the landscape in 2023. In Indonesia, PEMA Aceh will kick off a detailed study of the development, implementation, and operation of the Arun CCUS Project. The study will evaluate the storage potential of the depleted Arun gas field, and whether existing wells, pipelines and facilities can be repurposed. We will see Norway's Northern Lights inch closer to operational reality. The project boasts the best of both worlds: geologic understanding from depleted fields and vast aquifer storage capacity. In phase one, CO2 will be injected into the Lower Jurassic Aurora sandstone reservoir just south of the Troll West field. CO2 is expected to migrate updip through the aquifer over time. Drilling began on phase one wells mid-2022 and will continue through 2023 with first CO2 injection expected in 2024. We expect the nominal capacity of phase one to be 1.5 Mtpa, and up to 5 Mtpa capacity in phase two,” reads the report.
