Burner Fire Control

Concerns & Solutions

Concerns:

1.Radiation Intensity:

British Thermal Units p/hr. p/sq. ft.	Kilowatts p/sq. meter	Pain Threshhold (seconds)
500	1.74	60
740	2.33	40
920	2.90	30
1500	4.73	16
2200	6.94	9
3000	9.46	6
3700	11.67	4
6300	19.87	2

2.Radiation Effects: Whenever large quantities of flammable are burned, the potential heat release is sufficient to warrant consideration of its effects on personnel and equipment. The services offered by Burner Fire Control, Inc. eliminate these problems.

3.Personnel Exposure: Investigations have been undertaken to determine the effect of radiation on human skin. The accompanying table gives information of experiments performed on human subjects to determine the exposure time necessary to reach the pain threshold. With this table and our calculations, it can be determined if Burner Fire Control's Heat Protection Screen is required.

4.Equipment Exposure: In most cases, equipment can safely tolerate higher degrees of heat density than those defined for personnel. However, if anything vulnerable to overheating problems is involved, such as, construction materials that have low melting points (for example: aluminum, plastic or rubber) flammable vapor spaces or electrical equipment. Then the effect of Radiant Heat may need to be evaluated.

5.Additional Concerns:

High flow rates during extended well testing periods

Radiant Heat exposure to equipment and personnel

Changes in wind speed and direction (ie. crosswinds)

Inadequate heat suppression tactics/systems

Dual and simultaneous well testing conditions

(New) High performance burners

Structural integrity of the rig

Repair costs following high rate tests

Shut-ins due to extensive radiant heat

Crane/Escape vessels/etc. protection from excessive radiant heat

Personnel protection from excessive radiant heat

Adequate flare periods to record required performance data

Utilization of short flare booms in situation where longer booms would be required

The Burner Fire Control Water Curtain� is the solution:

Burner Fire Control's Water Curtain� has been in use for over twenty (20) years and has not experienced one job that damage has occurred to the main structure during drill stem testing regardless of the flow rate.

We have safely achieved gas flow rates of 125 mmcfd and oil flow rates of 16,000 b/day.

To ensure maximum safety, Burner Fire Control conducts a pre-job survey to determine the required amount of equipment needed for the drill stem well test on the rig.

The Water Curtain� System can be tailor-fit to any rig, production platform, drill-ship, fire boat, barge, etc. that needs heat suppression protection.

The Water Curtain� system is the only proven system recognized by major testing companies operating in the world at present time.

Burner Fire Control can provide calculations for expected amounts of radiant heat (BTU's) to be generated by flare. These calculations will determine if our services are needed and to what degree.

The Water Curtain� Heat Protection Screen has been designed to eliminate excessive BTU exposure to personnel and equipment.
