Restore caprock integrity

When an operator assesses a mature reservoir and determines the output is no longer economically viable, the decommissioning phase is the next step. Among the many considerations is making sure the well abandonment process restores the seal at the caprock for long-term protection against potential fluids migration.

Wellbore isolation using cementing fluids is crucial to restoring the integrity of the reservoir caprock by sealing each well with a permanent, leak-free barrier, enabling the operator to meet compliance obligations. And because any intervention can be complex, Schlumberger offers a fully managed cementing service, along with a line of cement solutions for well plug and abandonment campaigns with varying intricacies.
