  • Extended Batch, injecting a specified amount of chemical over a designated length of time

Why Use Pig Sweep?

The Pig Sweep™ process is raising the bar for pipe cleaning services as well as allowing for the smooth flowing of oil and natural gas from the source to the refinery. Saving expensive and time-consuming testing and tailoring of your cleaning solutions

In the past, the technology required a sample of the pipe wall debris to be taken and a special chemical solution was created to address the specific contaminants. In many cases, more than one chemical cleaning run was needed, using multiple products to address each kind of unwanted debris and sludge. This resulted in additional time, money, lost production and often affecting dew point and odorant fade.

sludge and debris from Pig Sweep process

To address this, E&P has created the first nanoparticle mechanical cleaning process for oil and natural gas pipelines.

Our patented process, Pig Sweep™, uses a nanoparticle solution which is filled with wedged-shaped positively charged nanoparticles that are only 10-12 nanometers thick. This is half the thickness of the skin of a red blood cell. This allows Pig Sweep™ to penetrate and coat every possible surface of the contaminants in a pipeline. This solution of nanoparticles is in constant motion. The positively charged particles repel each other and seek out the negatively charged electrons in the pipe walls.
