History
PSI-WS7 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.

Services with PSI-WS7
• 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
•PSI-WS7 is a charge soap or an anionic surfactant
•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 PSI-WS7?
Features of PSI-WS7
• Single product – multi purpose surfactant• 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 in most cases can reduce overall
costs of chemical program
Benefits of using PSI-WS7
•Pipeline dimensions•Product being transported•Flow rates•Gas and oil analysis•Facility size•Availability of injection points, pumps•Services available: power, water, workforce camp•Brief history of identified problems•Specifications of equipment related to problem
Application considerations for PSI-WS7
Application benefits of PSI-WS7• No limiting or restricting flow during injection
process
• PSI-WS7 works quickly giving improved performance of valves, instrumentation and plant efficiency
• Results often seen in just 24 hours:• sales tanks cleaned• flare tanks cleaned• process vessels and lines cleaned• clean and clear separation of water

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!
