OECD 302B test results conclude Exalt- Syn HCR to be Fully Biodegradable.

Exalt-Syn HCR has a very low bioaccumulative potential based upon literature bioconcentration factors and log Kow.

APPLICATIONS Exalt-Syn HCR can be utilized in any

situation where the removal of scale ormineral deposits is required and can safelybe used in place of conventional acids

Due to its immediate, and comprehensivespending nature Exalt-Syn HCR is anextremely effective oilfield stimulationproduct, and can be utilized for fracturingspearheads, scale removal, matrix squeezes/soaks, and hydraulic fracturing

PERFORMANCE

EXALT-SYN HCR ACID

CORROSIONWith inherently low metal corrosion properties, Exalt-Syn HCR is able to achieve corrosion rates on any typical oilfield grade steel well below conventional acid systems. Even at temperatures in excess of 100°C Exalt-Syn HCR provides wellbore protection below the acceptable corrosion limits set by the industry.

Temperature Corrosion Rate 50% HCR @ 50°C 0.001 lb/ft² @ 6 hrs (J-55) 50% HCR @ 70°C 0.003 lb/ft² @ 6 hrs (J-55) 50% HCR @ 90°C 0.006 lb/ft² @ 6 hrs (J-55) 50% HCR @ 90°C 0.004 lb/ft² @ 6 hrs (N-80)

STORAGE While Exalt-Syn HCR has exceptionally low associated corrosion rates on steel, it is recommended that product be stored long-term in drums/IBC totes, fibreglass/HDPE tanks, or approved acid lined tanks. Fittings and valves should be HDPE, brass, or stainless steel, rather than the typical cast iron.

Short-term storage (<72 hours) and/or delivery methods can include steel or lined steel tanks, however there is a small risk in product contamination from previous fluids with this method.

If heating of the product is required it is suggested to utilize a stainless steel heat exchanger or tank steam coils if equipped. Ensure the temperature of the heating fluid is kept to 65°C or below so as not to alter the fluid properties.

SAFETY REQUIREMENTSDue to the very low exposure risks associated with Enviro-Syn HCR there is no critical safety equipment required for handling. With the irritancy rating of the product it is required to ensure there is access to an eye wash bottle/station at a minimum for every operation. Exalt-Syn HCR is considered an acid, therefore appropriate chemical handling PPE is always recommended, as well as an operational risk assessment for each situation. Determination of a safety shower will be dictated by the risk assessment, or operator safety policies.

SHIPPING & HANDLINGAs Exalt-Syn HCR has a pH of less than 2 chemical approved fittings, hoses and pumping equipment should always be utilized. Exalt-Syn HCR is considered “corrosive to 7075 aluminum @ 55°C” under the Transportation of Dangerous Goods regulations. Class 8, Packing Group III placards and labels will be displayed, however it is NOT corrosive from a skin/eye perspective. Exalt-Syn HCR can be shipped in IBC tote containers, or by bulk container methods, and has a storage life of over one year - keep container closed when not in use. As with all chemical products and materials take care as to how you handle and where you store them. Personal protective equipment (PPE) is suggested for use when handling this product; however no special gloves or suits are required. Consult MSDS for complete handling instructions.
