Main scale-inhibitor treatment, which contains the inhibitor chemical, is normally in the concentration range of 2.5 to 20%. Angiotensin-converting enzyme inhibitors (ACE inhibitors) are a group of medicines that are mainly used to treat certain heart and kidney conditions; however, they may be used in the management of other conditions such as migraine and scleroderma.. Contact us for a meeting. These precipitates are alkaline earth metal scales. Oilfield scales are generally inorganic salts such as carbonates and sulfates of the metals calcium, strontium, and barium. In a scale-inhibitor squeeze, the inhibitor is pumped into a water-producing zone. These compounds form sludge, which, when properly conditioned with polymers, is removed from the boiler via blowdown. If properly selected, the scale inhibitor treatment concentrations of only a few ppm into the target stream may be effective to prevent scale problems. These are stable at the temperatures encountered in the reservoir, up to 245°C. ICG will be attending 2020 Specialty & Custom Chemicals America in Fort Worth, Texas Feb 10-13, 2020. Currently, the inhibitor of choice is Nalco 1340 HP, a polyacrylate, in dilute aqueous solution. Scale depositions occur with changes in temperature, pressure, pH or incompatible fluids. Specifically, the method is a novel "squeeze" application. The types of scale mainly include calcium carbonate, calcium sulfate, barium sulfate, barium sulfate, iron compounds and the like.

Home » Products and Services » Completion Fluids and Additives » Formation Protection » Scale Inhibitors. Different oilfield scale remediation techniques are known but majority are based on three basic themes: Phosphonates are used due to their cost-versus-performance ratio and are easily formulated by neutralizing to reduce their corrosivity and are easily made into combination (multiuse) products. Buy Central Heating Inhibitors at Screwfix. The scale inhibition mechanism of scale inhibitors includes four kinds of reaction complexation mechanism, lattice distortion mechanism, electrostatic repulsion mechanism, and … Due to the change of temperature or pressure for brine during production, the solubility of some of the inorganic constituents will decrease and result in the salts precipitating. The method of action of scale inhibitors depends on type. Cooling towers and chillers operate by running water through them in order to cool buildings or for “process” purposes in industrial settings. The detailed factors in the selection of scale inhibitor candidates for consideration in the performance tests include: Type of scale: Best scale-inhibitor chemistry based on the scale composition should be selected. When a significant excess of soluble orthophosphate and free hydroxide (caustic) alkalinity is maintained in the boiler water, calcium carbonate formation can be virtually eliminated.

Among the various types of oilfield scale inhibitors, the carboxylate/acrylate type segment accounted for the largest share in 2014. Phosphate esters, in some lower temperature applications, show better performance than phosphonates. The difficulty is even greater to increase the concentration of the product. In this type of treatment, a high-efficiency scale inhibitor is pumped into the matrix surrounding the fracture face during leakoff . In this article, a new kind of green scale inhibitor, carboxyl carbon quantum dots (CCQDs), was synthesized through a simple method of thermal decomposition of citric acid. Whether your problem is in the formation, downhole, emulsion lines or surface injection equipment, we can recommend the right product for your treatment. We carry chemicals to prevent both carbonate and sulfate scales, and products that work on barium and strontium scales. Phophonates, phosphate esters and polyacrylates are the three main types of scale inhibitors used in the oil and gas industry. For example, when the concentrations of calcium ion and carbonate ion exceed the solubility of the calcium carbonate reaction product, a solid phase of calcium carbonate scale will form as a precipitate. When combinations of these anions and cations are present in concentrations which exceed the solubility of their reaction products, precipitates form until their product solubility concentrations are no longer exceeded. Polymeric dispersants or sludge conditioners are added with the p… Oil field scales may also be the complex salts of iron such as sulfides, hydrous oxides, and carbonates. Scale inhibitors of alkaline earth metal carbonate and sulfates and transition metal sulfide are commonly used in oilfield applications. Phosphonates are used due to their cost-versus-performance ratio and are easily formulated by neutralizing to reduce their corrosivity and are easily made into combination (multiuse) products. Preferably, no scale inhibitors are used, and other ways of prevention are required. The scale inhibitor components mainly include some natural dispersants, phosphonic acids, phosphonic acids, and phosphonic sulfonic acids, and high molecular polymers. Inhibit the potential of minerals to form scale. The chemical dissolution involves the chelation of carbonate and sulfate scales using phosphorous and inorganic compounds. Phosphate treatment programs precipitate calcium and magnesium hardness from boiler feedwater in the form of hydroxyapatite and serpentine. Oil field scales may form in one of following two ways: 1. Most of the scale inhibitors and dispersants currently in use are high molecular polymers. Scale inhibitors can be applied down hole in a problem production well or in the surface facilities to delay the onset of these undesirable precipitates. A type of inhibition treatment used to control or prevent scale deposition. Some scale-inhibitor systems integrate scale inhibitors and fracture treatments into one step, which guarantees that the entire well is treated with scale inhibitor. Scale inhibitors are typically either phosphorous containing molecules or water-soluble polymers. PayZone ® SI 139 Scale Inhibitor. The scaling tendency can only be lowered by a chemical intervention on the production fluids: reduce the supersaturation of the salts in the water by inhibitors that form chemical complexes with the scaling ions. We also offer a variety of cleaning products for removing existing scale … By incorporating several types of functional groups into a single molecule, control of scale formation and deposition under more severe conditions than normally encountered can be attained.
