Permanent Caprock Integrity
Archer Oiltools' Stronghold™ systems provide an economical and effective alternative to traditional plug and abandonment (P&A).
- Barricade™: Archer’s field proven Barricade system perforates, washes, and cements the annulus, creating a rock-to-rock barrier in just one trip.
- Defender™: Archer's field proven barrier test system enables operators to perforate and test annular barrier.
- Fortify™: Archer's next generation barrier verification system used in plug and abandonment (P&A) and slot recovery. It is a superior system used to verify the integrity of existing annular barriers such as creeping formation and cement, ensuring Permanent Caprock Integrity.
By eliminating the need for milling, Archer’s Stronghold™ systems deliver a step-change in efficiency and effectiveness for P&A and other technologies.
Together with Tubing Conveyed Perforating (TCP) products and new charge development, Archer gives an efficient and safe execution of operations providing time and cost savings for our customers.
This paper provides an overview of the innovative new abandonment system elements and describes the successful deployment operation in detail.

A large number of oil and gas assets are coming to the end of their designed life expectancy and need to be decommissioned safely, securely and cost effectively.
Well integrity is concerned with the safe and reliable containment of all well fluids throughout the life of a well, including after decommissioning.
