Drill Green Petroleum LCI

• Non-pollution corrosion/scale inhibitor
• Protects both ferrous and copper alloy surfaces
• Water soluble

Consideration & Application

Cooling Water Systems

 DG LCI may be used in it’s neat form or diluted with soft water or ethylene glycol to any desired concentration. DG LCI should be added continuously into the system by means of a chemical injection pump or dripfeed device at a rate sufficient to maintain 50 to 100 ppm in the recirculating water. During the first several days of treatment, 200 to 300 ppm of DG LCI should be added to clean up the system and build a protective film of corrosion inhibitor. DG LCI is most effective in systems where the alkalinity of the cooling water is high enough to maintain a pH of 7.5-8.5.

Water Based Muds

DG LCI should be batched directly into anionic water based drilling fluids at an initial rate of 5 gallons/100 Barrels followed by the addition of 2 gallons/100 Barrels once every 24 hours. Highly corrosive systems may require increased concentrations.

Air Mist Drilling

DG LCI should be added to the make-up tank at the rate of ½ to 1-1/2 gallons per 10 barrels of mist water. DG LCI may be either batch treated or injected with a chemical pump on a continuous basis. Fluid pH should be maintained between 7.5 and 8.5 with the use of caustic soda. Care should be experienced to avoid contact with skin or eyes.

Common Procedures

The most common procedure is to drop the specified number of sticks to be dropped from the chart each time an additional joint of drill stem is added to the drill string in the drilling operating. As the fluid moves down the hole the surfactants and friction reducer will dissolve and penetrate the drilling fluids and slick up the metal surfaces. It is important to add the desired volume of stick each time a new joint of drill stem is added to the string to maintain the slick film on the metal surfaces.

DG LCI is shipped in 55 gallon steel drums as a Corrosive Liquid, N.O.S.
