Summary
BSEE reviews two well-abandonment incidents involving ejected travelling slips from hydraulic casing jacks. One caused crane-boom collapse; the other killed a supervisor and briefly left a well uncontrolled. Recommendations address reviewing slip-ejection hazards, considering alternatives to straight over-pull where pipe might part, and ensuring loads are free before crane lifting.
