9. Hot Oiling
The circulation of heated oil or similar fluids down a well bore, where the fluid dissolves and dislodges
paraffin and other hydrocarbon deposits. Related services involve the heating of oil storage tanks, which
eliminates water and other soluble waste that can reduce the operator’s revenue at the refinery.
Frac Heating
The heating of water being used in well frac jobs to a predetermined temperature, which prevents freezing
and ensures that fracing solutions mix properly.
Acidizing
Pumping specially formulated acids and/or chemicals into a well to dissolve materials blocking the flow of
the oil or natural gas. Acidizing is most often used for increasing permeability throughout the formation,
cleaning up formation damage near the wellbore and removing the buildup of materials restricting the flow
in the formation.
Pressure Testing
The pumping of fluids into new or existing wells or other components of the well system to detect leaks.

10. Fluid Management Services
Services include:
 transporting water to fill frac tanks or reservoirs at well locations,
 transporting contaminated water to disposal wells,
 moving drilling and completion fluids to and from well locations, and
 transporting flow-back fluids from the well site to disposal wells
ENSERVCO owns and operates a fleet of trucks, each of which has a hauling capacity ranging from 80 to
140 barrels.
Frac Tank Rental
ENSERVCO rents frac tanks to oilfield operators for storage of fluids at the well site. The tanks have a
capacity of up to 500 barrels and are used for storage of fresh water, salt water, flowback, temporary
production and mud. Frac tanks are used during all phases of the life of a producing well.
Construction and Roustabout Services
ENSERVCO derives revenue from its fleet of power units, which includes dozers, trenchers, motor graders,
backhoes and other heavy equipment used in road and well-site construction.
