PARC400® and Hot Oiling
Hot oil treatment, or "Hot-oiling", is a common method used to remove paraffin and asphaltene. Hot-oiling, however, has serious drawbacks that prevent it from being the primary method of paraffin and asphaltene removal in petroleum production. The use of PARC400® in conjunction with hot oil can decrease or eliminate most of those drawbacks.
To understand how PARC400® Chemical makes the hot oil treatment more effective and increase their safety we must first look into how hot-oiling actually works and each of the associated drawbacks.
When hot oil treatments are used, they are typically used for the removal of deposited paraffin and asphaltene in the tubing. Oil removed from a nearby storage tank is heated, then pumped down the annulus. While the hot oil is
While the pumping continues the paraffin and asphaltene is melted and removed along with produced oil. It is important to note that in most cases the hot oil used will be too cold by the time it comes back through the tubing to melt any paraffin or asphaltene deposited in the tubing. The heat loss through the casing and tubing is very high, hence, most of the work the hot oil does, it does on its way down.
Following are the main factors leading to problems associated with traditional hot oil treatments:
Because of the above, traditional hot oil treatments are considered to be the primary reason for formation damage as the paraffin and asphaltene introduced with the hot oil are now forced into the formation. The lower the formation porosity, the higher the probability of serious formation damage when hot-oiling.
The way PARC400® helps overcome these problems when used in conjunction with hot oil treatments is as follows:
