Stronghold® Systems

Archer Oiltools' Stronghold® systems provide an economical and effective alternative to traditional plug and abandonment (P&A).

Stronghold® Barricade® system: Archer’s field proven Barricade®+ system perforates, washes, and cements the annulus, creating a rock-to-rock barrier in just one trip.
Stronghold® Defender® system: Archer’s field proven barrier test system enables operators to perforate and test annular barrier.
Stronghold® Fortify® system: 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. 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.
