Restoring Caprock Integrity with Plug and Abandonment Services
When operators reach a point where a mature reservoir is no longer economically viable, the decommissioning phase becomes crucial. At this stage, one of the key considerations is ensuring that the well abandonment process restores the seal at the caprock to prevent potential fluids migration in the long term. Wellbore isolation utilizing cementing fluids plays a vital role in reinstating the integrity of the reservoir caprock by creating a permanent and leak-free barrier in each well. This essential step assists operators in meeting their compliance obligations effectively. Recognizing the complexity of any intervention during well decommissioning, Schlumberger provides a comprehensive cementing service managed by experts along with a range of cement solutions tailored for well plug and abandonment campaigns with varying complexities.
Choosing a Reliable Cementing Partner for Unanticipated Challenges
Effective decommissioning operations demand seamless collaboration between the cementing team and the operator's team. Mature wells often present unexpected challenges that require adaptability in isolation designs, products, and execution to achieve project objectives successfully. Working with Schlumberger ensures that experienced crews and global technical experts are by your side to manage these challenges and ensure the success of each project. Schlumberger also offers integrated well abandonment services with specialized technical offerings aimed at keeping costs and risks well under control.
