Self-Healing Cement that Gets Stronger with Salt Exposure

Aeternum’s chemistry is such that the intrusion of water into cracks causes reactions that form mineral crystals that seal and heal the cracks. Moreover, Aeternum gets stronger when exposed to salt water. Brines are almost always present where oil and gas wells are drilled, so Aeternum turns this normally corrosive material into a strength.

Aeternum also offers superior resistance to sulfate attack, commonly caused by formation fluids or groundwater.

Aeternum’s many economic benefits to the industry start with concrete that offers superior long-term zonal isolation and leak prevention. Using Aeternum can extend wellbore lifespan — potentially by decades – and reduce downtime and lost production. A typical well workover usually costs in excess of $1m, so avoiding or deferring is a huge economic plus. In oil & gas, fewer interventions mean safer operations, lower operational risks, and better compliance with regulations on well integrity and emissions.
