Summary
CSB investigates a fatal blowout and fire during tubing-head replacement at a Texas oil and gas well. It analyses inadequate well-control planning, ineffective hydrostatic and valve barriers, and ignition-source management. Recommendations address workover methods for underpressured reservoirs, well-history review and gaps in industry guidance and federal regulation.
