Last month CO2CRC drilled a 1,667 metre deep well over 30 days at its Otway Research Facility. The team successfully recovered 130 metres of core from the well. The three inch diameter core samples were taken at specified points during the coring operations. A core sample is a cylinder-shaped section of sediment or rock, obtained by drilling with a hollow steel core bit, with the core being recovered into aluminium tubes in nine metre long sections.
The core samples have now been sent off to a number of CO2CRC research partners for full analysis. The result will be an accurate insight into the formation conditions downhole, including porosity and permeability, amongst other characteristics.
