In addition to paraffin buildup, tars or asphaltenes occur in many crudes as colloidally suspended solid particles. Precipitation takes place when the crude loses its ability to keep those particles dispersed. The solids form a layer of tacky, gummy sludge on the bottom of the storage tank that grows over time and eventually must be removed. Many of the same factors affecting paraffin deposition also affect asphaltene deposition.
Clean up and removal of paraffins and asphaltenes is typically long and difficult and results in large volumes of hazardous waste that must be disposed at a hazardous landfill via incineration at a very large cost to the client. There are many methods for dealing with paraffin and asphaltene buildup in the industry. However, none are as clean and cost effective as Petrozene™, which has proved effective in helping dissolve solid or semi-solid paraffin and asphaltene deposits that form or collect near the formation face, piping, transportation and storage. Petrozene™ acts as follows:
- Reduces wax deposits in vessels improving operations.
- Reduces wax induced flowline restrictions.
- Reduces wax deposits downhole, increasing production.
- Reduces the pour point of paraffinic crude oils to meet contract specifications or improve flow.
- In addition to wellbore cleaning capabilities, the solvent can be squeezed into a formation to help remove asphaltenes precipitated within the reservoir.
