CASE HISTORY: GaS TreaT® 165FB-F

The Problem

Operators in the Eagle Ford Shale play have been faced with several

challenges presented by the use of triazine, such as:

Dump lines or dump valves plug: The spent triazine builds up in the

secondary vessel and carries over in the gas line. This requires the

operator to either shut in the wells or flare the gas (which may result

in EPA fines depending on permitting requirements). The lines then

have to be opened up and the spent triazine must be mechanically

removed, which incurs additional costs.

Products not properly winterized: The product solidifies in the

vessels. The operator is forced to shut in the producing wells

associated with the Ultrafab unit or flare the gas, which may result

in fines from the EPA. Then a hot oil truck is generally used to fix

the problem. In short, the hot oil truck pumps in hot water to “thaw”

out the chemical and get everything pumping again. This costs

~US$ 2,000 per incident.

Spent triazine is used up in the Ultrafab: It is then dumped out of

the secondary vessel and generally pumped into the produced water

tank. Sometimes the dump line is tied into the produced water line

and carried to the water tank. This often results in calcite (calcium

carbonate) scale formation and plugging of the flowline at the point

of the tie-in. Most producers now run the dump line directly to

the water tank and dump it in over the top to aid in dispersing the

spent product more effectively and minimize calcite scale. However,

calcite can and does still sometimes form because the scale inhibitor

package used was sub-par or inadequate.

The Solution

Gas Treat® 165FB-F was formulated to overcome all of

these common issues. The product, consisting of a scale

inhibitor package and other additives, decreases the amount

of overspent triazine scale formation. If any calcite does

form, the Gas Treat® 165FB-F inhibitor acts to disperse the

triazine, disallowing accumulation.

The product has been winterized to prevent setting of the

inhibitor in the Ultrafab vessels. Champion Technologies also

utilizes a scale package for effective mitigation of calcite

scale in flowlines and tanks. Because triazine scavengers

possess very high pH levels, they can significantly impact

calcite scaling issues.

Value

Champion Technologies saved the operator thousands of

dollars in cost avoidance through:

• Hot watering not being required during the winter to wash

out chemical that set up. This resulted in US$ 2,000

dollars cost avoidance.

• Additionally, most of the Ultrafab units for this operator

require either 250-450 gallons to fill the vessel for

operation. When vessels are hot watered due to chemical

setting up, it requires replacing the chemical in the

vessel which is very costly. Gas Treat® 165FB-F helped to

minimize associated costs.

• No dump lines have plugged since implementing Gas Treat®

165FB-F, saving operators money associated with crews

remediating and/or replacing plugged flowlines.

• No gas production was lost through gas flaring due to

Ultrafab units requiring repair or non-routine maintenance.
