How do you protect mature artificial lift oil wells from scale-related failure using a chemical free, sustainable approach? Daleel Petroleum LLC found the answer in North Oman, transforming a well plagued by recurrent rod pump failures into a long-term flow assurance success story.

Severe calcite scale had choked production equipment, dragging average run life down to just 159 days and forcing repeated, costly workovers. But by deploying ClearWELL’s electromagnetic scale control technology - a non-intrusive, surface-mounted system that transmits pulsed radio frequency signals downhole - they changed the outcome:

• Pump Run Life Extended: A massive 3.9x improvement from 159 days to over 627 days, before a corrosion related shut-in.
• Scale Accumulation Eliminated: Visual inspections that logged scale at all depths year-on-year suddenly showed zero scale.
• Chemical Use Avoided: 100% chemical- and intervention-free.
• Impressive Bottom-Line Impact: Dramatic reduction in OPEX, non-productive time (NPT), carbon footprint and HSE exposure.

This field-proven trial demonstrates that sustainable flow assurance technologies aren't just great for the environment, they’re highly profitable for long-term production optimisation.
