## Abstract

A technique for controlling an oilwell fire is provided which utilizes boxes (10, 40, 60) formed of autoclave cellular concrete. This material is sufficiently heat resistant to survive the temperatures of a burning oilwell and provide the possibility of extinguishing the fire and creating a mechanism to put the oilwell back into production with relative ease.

## Claims

### Claim 1

An apparatus for extinguishing a well fire at a well comprising a box formed of autoclave cellular concrete having four sides and a top, the box being placed over the well to control the fire, and a second box formed of autoclave cellular concrete, said second box having four sides and top, the second box sized to fit over the first box to provide additional control of the well fire.
