Join us for more information on citric acid in drilling fluids. Citric acid (C6H8O7) is a white, odorless crystalline powder. It is a weak multi-purpose organic acid that is widely used in oilfield completion and excitation operations. Citric acid has many benefits for use in drilling mud, and a significant portion of this acid is supported in the drilling industry in global markets. This acid is present in anhydrous and monohydrate forms, the main difference being in powder form and the second in liquid form. Citric acid, due to its relative ease and safety in operation, can be used to adjust the pH of drilling fluids, complementary fluids, and industrial waste liquids and oil wells.
Citric acid is used in drilling fluids as an important agent. An industrial chemical used to remove dissolved calcium from flowers. Purpose and use of citric acid in drilling gas and oil wells is used to neutralize cement in mud. This acid removes calcium ions from the drilling mud. This industrial chemical is used to reduce the level of hydrogen (pH) in drilling mud and has anti-corrosion properties. Reduces the risk of polymer mixing (xanthan gum, etc.) by interacting with equipment alloys and prevents the breakdown of highly molecular polymer networks during mixing. Citric acid is used to reduce the pH of drilling fluids and therefore to treat cement contamination. It also acts as a polymer stabilizer. It is commonly used as a pH control to reduce alkalinity and also plays an important role in transporting cuttings and removing calcium from drilling fluids. It can also help reduce the need for water and the backlog of oil well cements. Citric acid can be used as a cement additive as a barrier as well as a cement dispersant. Normally, between 0.1 and 0.3% by weight is used in terms of cement. It can also be used in a wide range of applications where the pH of aqueous liquids must be reduced. Widely used as an iron receiver in oil field completion and excitation operations. It can also be used in complementary liquids and wastewater from industrial oil wells. Citric acid is one of the factors used to separate oil fields. It is cheap, safe, effective and easy to work with. Its temperature limit is 200 degrees Fahrenheit (93 degrees Celsius) and 10 degrees Fahrenheit (-12.2 degrees Celsius). Citric acid with many uses from the past to the present Citric acid with the general formula C 6 H 8 O 7, which was discovered many years ago and its first use is related to beverages. It is also found in fruits such as lemons or oranges and is found naturally in nature. However, today the use of this acid is not as limited as in the past and in addition to the food industry, it has a wide range of applications from drilling oil wells to being used in food as a flavoring additive. Citric acid has varying degrees in industrial or food grade.
It has little reaction compared to some acids and is also a non-toxic acid that makes it available for use in the food industry. This acid is available in two types, industrial and natural, with different grades. Another property of this acid is its high solubility in water for 169 g / 100 ml at 20 ° C, which is very suitable for this acid.
Citric acid with a high level of decalcification of good acidity is used in drilling systems as an economical cost-effective acid compared to other acids. On the other hand, it has many applications for flavoring or use in food industry or dye making. It is a useful acid in all global markets. Some other acids such as acetic acid, formic acid, etc. have similar properties to this acid. But due to their high corrosion, price and transportation, citric acid is a good choice. Citric acid is flammable in any form and should be avoided in hot places. As the pH of citric acid is about 4.8 and it is corrosive, it should not come into direct contact with the skin and eyes and also avoid inhaling this substance. Because it can harm the body. Due to this, this acid needs standard packaging and safe transportation in any type.
