Paraffin Inhibitor Sticks


PARAFFIN INHIBITOR STICKS™ are primarily used to prevent paraffin deposition in crude oil production systems. PARAFFIN INHIBITOR STICKS™ are not designed to remove existing paraffin deposits but can soften these deposits and often make conventional paraffin cutting operations easier and faster.

PARAFFIN INHIBITOR STICKS™ inhibit paraffin deposition by the crystal modification method. This method keeps paraffin particles from sticking together. PARAFFIN INHIBITOR STICKS™ are effective on certain ranges of molecular weight paraffins. Testing the sticks for effectiveness can be done by simply trying the sticks in the field or by testing the crude oil in the laboratory. To be effective, the inhibitor must be in solution in the oil before paraffin precipitation starts to occur.


PARAFFIN INHIBITOR STICKS™ are very economical (as compared to conventional paraffin cutting and removal operations) and can eliminate or delay the need for conventional paraffin removal operations. Continuous treatment with PARAFFIN INHIBITOR STICKS™ (especially after a conventional paraffin removal job) can extend the time period between future operations.

PARAFFIN INHIBITOR STICKS™ are safe to handle and easy to use by less experienced field personnel and are compatible with normal oil field corrosion inhibitors and production chemicals.

PARAFFIN INHIBITOR STICKS™ can be dropped directly into a producing well or inserted into an oil flow line (using a T-Connection Pipe) or dropped into the oil storage tanks. Dropping the sticks directly into the well is more desirable as more of the production system can be protected.


The number of PARAFFIN INHIBITOR STICKS™ is based on the volume of crude oil to be treated. Laboratory tests indicate that periodic treatments of 50 PPM can help control paraffin deposition. A treatment of 50 PPM would require 0.37 lbs of PARAFFIN INHIBITOR STICK™ per 24 BBL’S (1,000 gallons) of crude oil produced.

Superior results are obtained by using PARAFFIN INHIBITOR STICKS™ regularly and immediately after a well is cleaned. To successfully control any paraffin problem, the inhibitor insertion into the fluid stream much be constant and be present in fluid before paraffin deposition starts to occur. For best results in intermittent treatment increase the number of sticks accordingly. Stick will float and dissolve at oil and water contact point in well.


The stick will dissolve slowly in 1 to 4 hours and release inhibitor gradually into the production system depending on temperature, crude oil solubility, and relative fluid motion. The stick will melt at 140ºF. The stick will dissolve in oil in wells with BHT less than 140º (just at a slower rate). The specific gravity is 0.83. The falling velocity through oil is approximately 100 feet per minute.

As in all industrial chemical, contact with eyes or skin should be avoided. Wash thoroughly with water. Sticks should be stored in a cool dry place. Refer to MSDS sheet before using. Always remove stick from plastic bag before using. Bag can be used as a glove to avoid contact with hands.
