Minor HCR after wireline snapped

Cause & Consequence

• Uncontrolled release of a flammable gas or liquid

Incident Location

Fixed Installation

Incident Activity

Production operations

Specific Incident Equipment

Wire line equipment

Lessons Identified

• Fluids should be sampled prior to pumping into a well on future interventions.
• Any changes to a well intervention programme should be fully reviewed, risk assessed and documented. This risk assessment should cover all potential “what if” scenarios.

Incident Recommendations

• Procedures to be modified to include testing of fluids to confirm contents prior to pumping into wells.
• Installation of hard piping and additional signage to prevent contamination of tanks with other fluids.
• Review procedure for management of change during wells intervention operations.
