Reagents and materials for acid treatments

SLICK A Thinner, Friction reducer

SLICK A is a high molecular weight copolymer designed to perform well in water based fracturing fluids, acids and brines. SLICK A is a cationic polymer emulsion useful in fracturing and acidizing applications as friction reducer additive. Recommended dosage levels range from 0.25-1.0 gal of SLICK A per 1000 gal of water or HCl solution, with reduction in friction pressures by greater than 60%.


SURF NM Non-emulsifier

SURF NM is a highly effective non-ionic, non-emulsifier that prevents emulsions in both acid and fracturing fluids and is designed (a) to have excellent compatibility with a variety of acidizing or fracturing compounds such as corrosion inhibitors, iron control agents, anti-sludge agents, gelling agents and crosslinkers and (b) to deliver a very low surface tension, aiding in wettability and water recovery. SURF NM contains surfactants which deliver superior break times normally within 60 seconds even in the presence of crude oils with a high probability for sludge build-up. It is designed to be formulated in HCl acid or in a fracturing fluid at dosage levels ranging from 0.50-2.00 gal of SURF NM per 1000 gal of base fluid for non-emulsification purposes and offers an extremely cost effective and high quality alternative compared to other products.


CORR HT Corrosion inhibitor

CORR HT is a moderate to high temperature corrosion inhibitor designed to give excellent protection when in contact with common oil and gas well steel conduits in acidizing applications. CORR HT has no aromatic solvents, alkyl phenols, quaternaries or heavy metals, and is effective in all HCl acid strengths up to 28%. CORR HT is able to provide corrosion protection up to 350°F. CORR HT may be added to the dilution water prior to the addition of concentrated HCl. This product is normally utilized in concentrations ranging from 0.50 to 30 gallons per thousand gallons of acid. The concentration of CORR HT corrosion inhibitor is determined by: (a) the type of steel, (b) the downhole treating temperature, (c) the acid type and concentration and (d) the planned contact time of the acid with the steel.


CORR LT Corrosion inhibitor

CORR LT is a low temperature corrosion inhibitor designed to give excellent protection when in contact with common oil and gas well steel conduits in acidizing applications. CORR LT is effective in 28% HCl acid solutions at temperatures up to 200°F and greater than 200°F in 15% HCl acid solutions. Higher concentrations of CORR LT may be used at higher temperatures if certain types of steel are being used. CORR LT also shows excellent performance and solubility in HCl-based systems designed for use in industrial applications. Recommended dosage levels range from 1.0 — 6.0 gal CORR LT per 1000 gal of HCL solution.


CURE A Corrosion inhibitor,Iron Control, Non-emulsifier

CURE A is a proprietary, economical acidizing product used in Hydrochloric Acid (HCl) to provide corrosion inhibition, iron control, and non-emulsifying properties to the acid in one convenient product thereby reducing the need for multiple product inventories. CURE A can be used «as is» in 15% or 20% hydrochloric acid treatments to a bottom-hole temperature of about 130°F. For applications greater than 130°F, for 28% acid, or for use through coil tubing additional corrosion inhibitors are recommended. CURE A is recommended at loadings of 6 to 8 gal per 1000 gal of HCL solution.


C-IRON Iron control

When appreciable quantities of iron in the ferric ionization state (Fe+++), as opposed to the more typical ferrous state (Fe++), are dissolved by the acid, iron precipitation and permeability reductions can occur after acidizing. Sources of iron include (1) corrosion products found on the walls of the tubular goods, (2) pipe scale, and (3) iron in mineralogical form in the formation. The ratio of ferric to ferrous iron governs precipitation.
As the pH of the fluid increases during acid spending, the dissolved iron can precipitate. This can lead to formation damage during sandstone matrix acidizing operations. Sludges and emulsions will be formed in many crude oils when ferric iron is present. C-IRON is used to reduce the iron in the acid from ferric (+3) to ferrous (+2) state. This reduction allows the ferrous iron to be produced out of the reservoir without permeability damage. Concentration of use is shown in the graph on the next page. Recommended dosage level is 2 gal per 1000 gal of liquid per each 1000 ppm of Iron ion contamination.


SCALE Scale precipitation control

SCALE is a phosphorous based chemical in an aqueous solution and used for the prevention of scale buildup. SCALE is extremely effective at preventing calcium carbonate and calcium sulfate scale, as well as inhibiting barium sulfate scale. SCALE can tolerate very high concentrations of salt (NaCl, KCl), increased levels of metal impurities in solutions and higher alkalinity levels. SCALE can be added directly into the fracturing fluid to prevent flash scale formation. SCALE will also plate out on the formation face to inhibit growth of scale over time. Recommended dosage levels range from 0.50-1.00 gal of SCALE per 1000 gal of base fluid, but testing is recommended before use.
