The oil and gas industry has long grappled with the persistent challenge of non-productive time—those costly operational delays that silently erode project budgets and timelines.

For drilling operations in Nigeria’s Niger Delta, where geological complexities intersect with logistical constraints, these inefficiencies have historically represented a significant barrier to field profitability. Yet a growing movement toward integrated service quality models is beginning to reshape how operators approach well delivery.

Joshua Emeka Ozor, a drilling engineer at First Hydrocarbon Nigeria working on the OML 26 asset, has emerged as a vocal advocate for systematic quality management reform in workover operations. In a technical paper presented at the SPE Nigeria Annual International Conference, Joshua Ozor and his co-authors argue that traditional quality assurance tools, while valuable, no longer suffice in isolation. Instead, they propose Agile Quality Management—a dynamic framework that embeds quality considerations into every stage of well delivery, from initial design through final handover.

The approach isn’t merely theoretical. Joshua Ozor’s team deployed AQM across six workover wells in OML 26’s Ogini and Ozoro fields, establishing what they termed the “3-7-21” performance benchmark: delivering wells with 3% non-productive time, on a $7 million budget, within 21 days. The methodology combined cost-of-quality analysis with lean modeling and operational readiness audits, creating multiple checkpoints to identify potential failures before they materialized on location.

According to Joshua Ozor, the shift from reactive to proactive quality management represents a fundamental reimagining of drilling discipline. “We’re no longer waiting for defects to appear during execution,” he explains in the paper. “By deploying tools like the Operation Readiness Matrix during planning, we can audit contractor preparedness across process complexity, equipment availability, and personnel competency—closing gaps before the rig mobilizes.”

The results from OML 26’s workover campaign validated the model’s effectiveness. While the team fell short of their ambitious 3% NPT target, they achieved measurable reductions in downtime across the six-well program, with all wells delivered under budget. Oz-A1, the pilot well for AQM implementation, established baseline performance that improved progressively through subsequent operations as the team refined their processes.

Joshua Ozor’s work on the campaign built upon his earlier experience as a well-site drilling engineer, where he managed real-time operations including casing runs, cementing calculations, and drilling performance monitoring. His transition to a design-focused engineering role in 2019 positioned him to influence operations at the planning stage—precisely where AQM delivers maximum impact.

The significance of this work extends beyond cost savings. By integrating Total Quality Management principles with agile methodologies originally developed for software engineering, Joshua Ozor and his colleagues demonstrate how drilling operations can borrow frameworks from adjacent industries to solve persistent challenges. Their Operation Readiness Matrix, for instance, adapts ISO auditing standards with API specifications, creating bespoke tools tailored to upstream operations.

The paper also acknowledges AQM’s limitations. Hierarchical approval structures can slow change requests, and critical path scheduling becomes complex when multiple teams work simultaneously. Yet these constraints haven’t diminished enthusiasm for the model within OML 26, where it now informs planning for new drilling campaigns.

For an industry historically resistant to methodological disruption, Joshua Ozor’s advocacy for systematic process innovation represents a quiet but significant shift—one that prioritizes operational excellence through disciplined preparation rather than reactive problem-solving.
