SureThermSM Service for Paraffin Removal - Halliburton

PIPELINE AND PROCESS SERVICES
As heat is released, the temperature of the pipeline fluids are
elevated and the paraffin gradually melts or dissolves into the
production flow. If the pipeline is shut down, the SureTherm SM
service treatment can be designed to deliver a targeted release
of heat at the location of the most severe paraffin deposition.
Appropriate addition of a solvent such as Paragon agent can be
considered to enhance the paraffin removal process.
The products of the reaction are salt, water, nitrogen gas and heat.
These are all environmentally acceptable.

Operational Aspects
Any SureTherm service operation begins with a careful
consideration of the engineering aspects of the treatment. In
addition, testing of the proposed SureTherm formulation must be
completed with the water that will be used for the treatment.
This confirms that the desired delay time can be achieved.
The SureTherm service is based on a catalyzed reaction between
two components to produce a large amount of heat. The catalyst
used in the SureTherm service is a proprietary, solid-phase material
that provides a delay in the onset of the chemical reaction. Based
on temperature, allowable treatment pressure, and the chemistry
of the water system, separate solutions containing appropriate
concentrations of the two basic components are prepared and
stored in separate tanks. When the treatment is to be pumped, an
appropriate amount of catalyst is added to one of the components
and the two separate fluids are simultaneously injected into the
pipeline (Figures 4).

Enhanced Environmental Performance
The reaction products are sodium chloride (common salt), water,
nitrogen gas and heat. Compared to traditional paraffin solvents
or dispersants, both the initial reactants and reactant products
associated with the SureTherm service pose considerably less threat
to personnel and the environment.
