This week, we’ll be in Bakersfield, California, joining peers from across the country at the 2nd Annual Orphan, Idle & Marginal Wells California Conference. For those of us working directly on well plugging and abandonment, this gathering comes at an important moment.

Across California — and well beyond — states are facing a growing inventory of orphan, idle and marginal wells. Many of these wells, drilled in the early and mid-20th century, were left without proper documentation or closure, leading to methane leaks, soil and groundwater contamination and safety risks to nearby communities.

From our perspective, conferences like this matter because they create space for honest, technical conversations about what is working, what is not and where programs still struggle.

Why This Work Matters to Us

Both of us dedicate our days to the intricacies of well abandonment, engaging in project planning, navigating regulatory requirements, coordinating field teams and addressing unforeseen issues that arise once operations commence. Each site and well presents unique challenges, frequently extending beyond purely engineering concerns to include data deficiencies, community considerations and long-term land use planning.

Alex’s work focuses heavily on subsurface investigations and remediation across Southern California, including sites with complex contamination histories and limited documentation. Much of that effort involves review of historical aerial photos, available public/private records and aligning closure activities with broader environmental compliance goals.

A.J.’s role centers on leading engineering, operations and risk management for complex orphan, idle and marginal wells — reconstructing incomplete well histories, designing abandonment programs that are technically sound, regulatorily defensible and executable in the field. That often means balancing cost, safety, environmental protection and uncertainty, all at once.

What connects our work is the belief that successful closure programs rely on collaboration — between engineers, geoscientists, regulators and communities — and on the smart use of modern tools.

Sharing Lessons from the Field

At the conference, A.J. will be presenting “A Well Abandonment Journey Overview,” which draws directly from real‑world project experience. The presentation will walk through how teams are approaching complex abandonment projects today, including:

• Reconstructing well histories when records are incomplete or missing.
• Using drone‑based geophysical tools to help locate undocumented wells.
• Integrating engineering design with field execution to reduce surprises.
• Applying risk‑based planning to prioritize work and protect communities.

These are not theoretical concepts — they’re lessons shaped by what we see on the ground. Our goal in sharing them is to contribute practical insights that others can adapt to their own programs.

The Value of Coming Together

The technical challenges around orphan and idle wells are significant, but so are the opportunities. We’re seeing encouraging progress as states invest in closure programs and as the industry becomes more open to new technologies and cross‑disciplinary approaches.

What we value most about this conference is the opportunity to listen — to hear how others are addressing similar challenges, to learn from different regulatory environments and to understand community perspectives that shape how projects move forward. These conversations help refine practices and, ultimately, improve outcomes.

As national efforts to address legacy wells continue to scale, the path forward depends on shared learning and sustained collaboration. We’re looking forward to being part of that conversation in Bakersfield — and to carrying those insights back into the work that continues long after the conference ends.
