Selvol™ Premiol Product Information
Productivity, performance, and cost control.
Fluid loss control is one of the oil industry’s highest concerns. It affects productivity, performance, and cost—not to mention the environment and safety. Selvol™ Premiol oilfield performance products, released in 2005, represented a new beginning for Sekisui Specialty Chemicals in the oil field industry.
Listening to the needs of the industry, Sekisui Specialty Chemicals set out to tailor new solutions to address oil field challenges—Selvol™ Premiol is the culmination of this research.
Currently used primarily for cementing and drilling, Selvol™ Premiol offers a potentially broad range of applications for the oil field industry in downhole applications. Target areas include acidizing, stimulation, workover, water management, and fracturing among others.
In an effort to develop laboratory and field data and deliver optimum performance and cost advantages, Sekisui Specialty Chemicals’s Selvol™ Premiol R D is supported by in-house cementing and drilling fluid labs staffed with personnel experienced in oil field applications.

Physical Properties
Selvol™ Polyvinyl Alcohol combines high tensile strength with ease of film formation. Additionally, Selvol™ Polyvinyl Alcohol resins show excellent adhesive and bonding characteristics.Partially hydrolyzed grades have better adhesion to hydrophobic surfaces.
The degree of hydrolysis affects the water sensitivity of both the resin and film. Water resistance increases with increasing hydrolysis. The super hydrolyzed grades should be used when maximum water resistance and humidity resistance are desired.
Selvol™ Polyvinyl Alcohol resins are generally unaffected by greases, petroleum hydrocarbons and animal or vegetable oils. Resistance to organic solvents increases with the degree of hydrolysis. Selvol™ Polyvinyl Alcohol film can be plasticized with glycerol or the lower molecular weight glycols. These materials generally act as humectants, holding water in the film.

Chemical Reactions
Polyvinyl alcohol resins react in a manner similar to other secondary polyhydric alcohols. Esterification reactions of polyvinyl alcohol can be carried out with a number of compounds. A commercially important reaction is the formation of tackified PVOH using boric acid or borax to form cyclicesters. This reaction is very sensitive to pH, and an insoluble gel is formed above 4.5-5.0.
Other esterification reactions include those with chloroformate esters to yield polyvinyl carbonate, with urea to yield a polymeric carbamate ester, and with isocyanates to form substituted carbamate esters.
Another commercially important reaction is acetalization with aldehydes. Polyvinyl butyral is produced by the reaction of polyvinyl alcohol with butyraldehyde and is used in the production of the inner adhesive film for safety glass. Reaction with dialdehydes such as glyoxal or gluteraldehyde can be used to crosslink polyvinyl alcohol. Other reactions include ethoxylation, propoxylation and cyanoethylation.

Addition rates, solids and cook out temperatures vary by PVOH grade as illustrated below. For best results, do not exceed maximum solids. Elevate solution temperature to recommended levels (185-205°F/85-96°C) and hold for 30 minutes.
Selvol™ Polyvinyl Alcohols are in solution after cooking and can be used at any temperature.
While the cooking process is straightforward, please be aware of the following pitfalls:
- All tanks and lines must be free of borax to avoid coagulation.
- Tanks should have baffles and flush bottom valves to avoid dead spots where polyvinyl alcohol can agglomerate.
- Failure to reach the minimum temperature will result in undissolved polyvinyl alcohol no matter how long it is cooked.
- Selvol™ Polyvinyl Alcohols cannot be overcooked. However, boiling will induce foam.
- Avoid high speed, small diameter mixers. These agitators do not provide adequate mixing and tend to entrain air.
- If a defoamer is used, it is best to add the defoamer prior to the polyvinyl alcohol addition to the water. A defoamer is not required with Selvol™ Polyvinyl Alcohol 805, 823 and 840 polyvinyl alcohols.
- If solutions are kept for more than 24 hours, a biocide addition is recommended.
- Selvol™ Polyvinyl Alcohols may be jet cooked. Unlike starch, which explodes in a steam jet, Selvol™ Polyvinyl Alcohols will dissolve by shedding layers. Maximizing time in the jet and providing a holding tank for the polyvinyl alcohol solution after the jet (where solutions may be held for a minimum of 15 minutes) will ensure complete solubility.
