History
PMI-107 has its origins 20 years ago in the Western
Canadian Sedimentary Basin. This development was
a new approach to dealing with the heavy paraffin
waxes and asphaltenes present in those limestone,
shale and sandstone formations. The product has
now been refined and has built on those early
successes with current activity in the Middle East,
backed up with independent third party verification.
• Paraffin and asphaltene wax formation
• Pipeline plugging or restrictions
• Corrosion of pipeline, tanks and equipment
• Wax build up in pipeline or plant facilities
• Scaling and emulsions
• Difficulties in removing H2S
• Excessive pressure, reduced volumes
• Low productivity
• High maintenance costs
Common problems
• PMI-107 is formed by using molecular chemistry to
make a charged or an anionic blended compound.
• It has an affinity for any positively charged carbon
or stainless steel surface, where it is drawn to the
steel it forms a protective barrier film
• Typically, results can vary depending on
project but can be as short as 24 hours
What is PMI-107?
Features of PMI-107
• Single product – multi purpose anionic compound
• Corrosion control and prevention
• Paraffin/asphaltene control and prevention (incl. crystalline wax)
• Drag reducer
• Cleans pipe lines, pumps, valves and equipment
• Cleans tanks and facilities
• Chemical injection services
• Well stimulation and work over
• Emulsion control and breaking
• Reduces maintenance down time
• Single product corrosion and wax inhibitor
• Solution drops out into the water and is water soluble
• Environmentally friendly and safe to administer
• Effective for onshore/offshore operations
• Cost effective and will reduce overall costs of chemical
program

Pigging with confidence! One year earlier, this pipeline was 100% plugged with wax
and suffering from corrosion. They now have a 0% BSW and visible results.

There was zero entry into the
tank and all but the in-organics
were recovered, shipped and
sold with zero downtime, while
dropping the emulsions to zero
and shipping 30,000 recovered
barrels of oil!
We can also remove the in-
organics without man entry into
the tank.

Leading market competitor @ 220ppm >10.00 mm/yr
PMI-107@ 220ppm 0.07 mm/yr
Lab report – “For both the welded and parent metal coupons,
general corrosion rates of approximately 0.06-0.07 mm/yr
were obtained at both concentrations of corrosion inhibitor,
indicating satisfactory corrosion inhibition and/or protective
film formation as the value is lower than 0.1 mm/yr.”

AIE report – “As with the tests performed at 220 ppmv, no
significant pitting was noted on the parent material of either
the welded or parent metal samples at a corrosion inhibitor
concentration of 300 ppmv. The absence of significant pitting
corrosion confirms the performance of the corrosion
inhibitor against pitting corrosion. .”

“The well produces very high internal corrosion rates and the pipelines suffer from high levels of wax deposition
which resulted in one of the pipelines becoming fully blocked.
PMI-107 was introduced into the field as a multipurpose product to primarily manage the internal corrosion risk and
prevent future blockages due to wax build up. Following its introduction into the field some 12 months ago, PMI-107
has marked a step change in terms of managing corrosion and wax in our pipelines.
During a stringent corrosion testing programme undertaken in the UK, the inhibitor was shown to exhibit the
corrosion rates to below industry standards and the field water sampling and coupon results have backed up its
solid performance in the field.
In addition to the wax and corrosion inhibition, we have gone from measureable amounts of water in the export
crude to virtually no water in the crude. Based on this product, we have been very impressed with the performance
of this chemical in both lab trials and field performance”
