Perforate, Wash & Cement

Our field proven Stronghold® Barricade® system is designed to perforate selected casing or liner sections; wash and clean the perforated zone completely; then enable permanent rock-to-rock cement plugging–all during a single trip. 

By eliminating the need for milling and debris handling, and preparing the seal zone to receive cement, the Barricade® System delivers a step change in plug and abandonment (P&A) efficiency and effectiveness.

Well assets are maturing and the need for reliable, cost-effective P&A techniques is increasing. Traditional P&A methods are often time consuming and costly. But decommissioning a well has to be done with permanent integrity in mind, and without compromise. The system provides an economical and effective alternative to traditional techniques. In designing the Barricade® System, our engineers focused on 3 key areas–efficiency, flexibility and reliability.

Perforate, Wash and Cement for Through-Tubing applications

The success of the Stronghold® Barricade® system has also been further developed for smaller Through-Tubing applications partially through a subsidised project by Total Energies (LAPA project). The concept and actual geometry has been validated for washing and cementing through CFD studies and currently a version for 5″ tubing/casing is available (Barricade CT/TT). A specific version with collapsible cups to navigate through restrictions such as Downhole Safety Valves is under development and testing which will further aid in moving to rigless abandonments.
