Acidification is one of the most effective technical measures for oil-gas well and water injection well stimulation during the carbonate reservoir development process. However, acid constituted a serious corrosion to the well in the production until 30's in twentieth century that the first batch of corrosion inhibitor was presented. Since then, the acid stimulation technology has got rapidly application and development. The principle is that, according to the acid dissolution and corrosion of the rock cement and cracks, to restore and increase the permeability of the formation porosity and fracture; and join the corrosion inhibitor with acidizing fluid, the underground pipe string and equipment could get effective protection during the acidification of construction process.
The acidification process includes acid pickling, matrix acidification and fracturing acidification. Acid corrosion inhibitor is one of the most important additives in the process of acid production. All the industrial acid applied in oil-gas well stimulation is required to be added to the corrosion inhibitor to reduce the corrosion rate of the well bore. With the development of drilling technology and the advancement of oil recovery technology, the investments of large numbers of deep wells, ultra deep wells and deep wells put forward higher requirement on corrosion inhibitor. As a result, exploit more effective corrosion inhibitors, such as higher acid resistance, higher temperature resistance and higher sulfur resistance are imperative on the basis of different stratal configuration.
L.E.A.D. offers a variety of
corrosion inhibitors to protect the equipments from corrosion effectively under different temperatures. They equip obvious advantages such as little dosage, good effect, no need special facilities etc. We integrated adsorption theory, deposition theory and electrochemical theory to develop more advanced corrosion inhibitor.
Also we could customize a corrosion-treatment program according to your specific needs by evaluating field conditons and fluid properties, main categories are as follows:
SL-CR-U-Ultra-Temperature-Corrosion-Inhibitor
SL-CR-M-Mesothermal-Corrosion-Inhibitor
SL-CR-H-High-Temperature-Corrosion-Inhibitor
Chemistry：Imidazoline based, Pyridine quaternary ammonium salt based, Mannich based etc.

Demulsifiers, or emulsion breakers, are a class of specialty chemicals used to separate emulsions (e.g. water in oil). They are commonly used in the processing of crude oil, which is typically produced along with significant quantities of saline water. This water (and salt) must be removed from the crude oil prior to refining. If the majority of the water and salt are not removed, significant corrosion problems can occur in the refining process.
L.E.A.D. offers a broad range of surfactants which perform well with the
heavy oil problem. Especially the silicone and AEC chemistry applied in the emulsion treatment. This series of products are mainly used in oilfield produced fluids of crude oil demulsification and dehydration, various different products for oil blocks, the different nature of the chemical dehydration solution mining. Products with less, dehydration rate, prolapse clear water, oil-water interface Qi, etc., to meet the complex fault block oilfield produced fluids of different oil-water separation requirements. Products are also used in oil refinery desalter wash salt treatment, and the main product:
