Result
MCGx managed commissioning-to-operations transition for a 180 MMscf/d dual-zone gas well, preventing integrity debt from accumulating across lifecycle handover points. Temporary commissioning decisions, including elevated annulus pressure limits and ICV control-line pressurisation, were formally closed out and converted into defendable Operate-phase controls rather than inherited as undocumented constraints.
Problem
Commissioning requires temporary compromises: elevated pressure limits to avoid shutdowns, workarounds for equipment anomalies, and monitoring strategies that don’t scale to long-term operations. Without deliberate lifecycle governance, these temporary measures become permanent operational constraints, limiting future flexibility, creating undocumented risk, or forcing costly interventions to restore design intent.
MCGx Insight
MCGx recognized that the highest-value commissioning activity isn’t perfect execution; it’s maintaining integrity continuity through lifecycle transitions. By establishing clear handover criteria six months before startup, validating them during commissioning, and formally transitioning temporary controls into Operate-phase governance, integrity accountability remained unbroken from planning through sustained operations.
Proof
All temporary commissioning MOCs were closed out with permanent controls documented in operating procedures. The well entered operations with known limits, validated surveillance methods, and no undocumented constraints inherited from start-up.
