There are thousands of conventional oil and gas wells that date back to the early part of the last century. These wells suffer extensive corrosion and metal loss. As newer wells — especially those in unconventional fields — are drilled and completed in close proximity, the resulting fractures may create unintended communication pathways with older wells in the area. Proper plug and abandonment (P&A) of older conventional wells mitigates this issue.
With decades of experience, a global footprint, and the broadest set of well-abandonment technologies in the industry, Weatherford provides a comprehensive solution scoped and managed by a single company. Our offerings help to reduce the complexity of P&A operations and ultimately lower costs.
Reducing initial abandonment costs as well as the probability of cost escalation due to scope creep
Addressing the backlogged inventory that has built up over the past 60 years
Standardizing competencies and practices to enhance efficiency and reduce P&A costs
Meeting the challenge of increasing work volumes with a single service provider
Our portfolio of differentiated technologies, broad onshore expertise, and flexible commercial models give us a unique approach to abandonment projects — represented by the Well Abandonment Advisor solution. Leveraging our significant knowledge base, we have developed a risk-based software tool that helps clients to more accurately plan and budget abandonment projects. As a single‑source provider, we can enter the P&A process at any stage and manage the project to completion safely, on time, and on budget.
Our three-step process enables proper scoping and risk assessment at the outset.
Through careful analysis of the well files, our team is able to develop an appropriate plan based on a modified turnkey model. This reduces the risk of scope creep and also distributes the risk so that the client is not left with a large, unanticipated bill toward the end of the project.
With an appropriately scoped plan in place, we engage third parties as needed to source specialized equipment and services. We also file applications with regulatory authorities as needed.
Finally, we oversee the execution of the project, from rig-up to close-out.
Technology is at the heart of our approach to meeting clients’ needs. We constantly update and refine our technologies to solve new challenges encountered in the field.
The SecureView service enhances the visibility of well-integrity issues by delivering a high‑resolution view of cement and casing. Weatherford is the only service provider that can capture this level of quality data in a single trip. If the SecureView service reveals a problem, we prepare the wellbore for remediation or abandonment using our comprehensive fishing, milling, and pulling equipment.
A critical element in compliant abandonment is establishing a rock-to-rock hydraulic seal across the borehole that mimics natural bedding. The Endura section mill cuts through and removes both inner and outer casing strings in a single trip using uniquely designed cutter blades, improving efficiency and making the wellbore easier to seal.
The QuickCut Pro service combines field-proven QuickCut casing-exit technologies with our patented and secure data tracking and transmission package: the AccuView™ system. This integrated solution delivers actionable real‑time data and consulting from subject‑matter experts to plan and execute precise casing-exit operations. The service can be applied to land and offshore abandonment operations.
The combination of our industry-leading technologies and our disciplined approach has produced measurable value for our clients.
