Silicone antifoams

Silicone antifoam in drilling mud used for drilling oil wells, prevents creating pesky foam which disturbs drilling mud rehology. One of the company’s silicone antifoam products that is approved by all south drilling consumers and has a certificate from research institute of petroleum industry is KZ2000s. Silicon antifoams are used in many petrochemical processes and also gas sweetening applications.

 

Non-silicone antifoams

Non silicone alcohol base antifoams are being used in drilling oil wells with some kind of the drilling mud to prevent creating pesky foam which disturbs drilling mud rehology. Also these alcoholic antifoams are used in cementing of oil well walls, while casing procedure.

Lubricant

A metal working fluid should impart sufficient lubricity between the tool and the work piece to cause a significant reduction in friction to occur. Friction is the resistance to the motion of one surface over another. Lubricants are used to reduce the frictional forces. High friction results in heat and because more force or power is necessary to move the parts relative to one another, this friction reduces operating efficiency, and in the case of metalworking, shortens tool life, affects surface finish, and increases production time. When the lubricant film is insufficient to protect the metal surfaces, there is wearing on one or both components. Thus, wear will directly affect tool life and the finish and quality of the work piece. When a lubricant is applied between the contacting surfaces, the friction and wear can be minimized.

Emulsifier

When water and oil are mixed together and vigorously shaken, a dispersion of oil droplets in water - and vice versa - is formed. When shaking stops the phases start to separate. However, when an emulsifier is added to the system, the droplets remain dispersed, and a stable emulsion is obtained.
An emulsifier consists of a water-loving hydrophilic head and an oil-loving hydrophobic tail. The hydrophilic head is directed to the aqueous phase and the hydrophobic tail to the oil phase.
These emulsifiers are divided into two groups: primary and secondary emulsifier:
Primary emulsifier based on esters are used as emulsifiers of water and oil, while the secondary emulsifier based on the polyamines, as auxiliary emulsifier that increase the primary emulsifier stability in emulsion, regulating HLB and also be  used as a wetting agent

Corrosion Inhibitor

Corrosion phenomenon is created by chemical or electrochemical reaction, usually between a metal and its environment which will lead to change the properties of matter. Corrosion inhibitor is a material that when added in low concentration, corrosion (rust) of a metal, alloy, pipelines in oil and gas industries, will be reduced or stopped. These corrosion inhibitors create a non-active layer on the surface of the metal and can stop oxidation process, or through reaction or absorption of the factors that lead to metal corrosion by which the metal surface is protected against this factors.

Anti scalant

Anti scalant is a family of chemicals designed to inhibit the formation and precipitation of crystallized mineral salts. Most of anti scalants are proprietary from organic man-made polymers. (e.g. polyacrylic acids, carboxylic acids, polymaleic acids, polyphosphates, phosphonates, anionic polymers, etc.).
One of the anti-scalant applications is using in reverse osmosis systems. In these systems, after a while, because the presence of dissolved salts in inlet water, the passing ways of membrane will cramp, this is called scaling.

Some of the materials that deposit on the membrane, are calcium carbonate (CaCO₃), calcium sulfate (CaSO₄), barium sulfate (BaSO₄) and strontium sulfate (SrSO₄). To prevent deposits on the membrane, the appropriate dosage of anti scalant is injected to feeding water.

Cement antifoam

Antifoams in cementing with a suitable formulation causes the gas encapsulated in cement composition to be escaped easily.
Features and benefits:

  • Can be used in oil fields and also the constructions of tunnels
  • Usable in different cements
  • Usable in fresh water, salted, saturated and sea water used in cement composition
