2. 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.

7. Common problems 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

8. What is PSI-WS7? 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

9. 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

10. Benefits of using PSI-WS7
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

11. Application considerations for 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

12. 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
