Abstract: A coiled tubing heating head tool system includes a tool connected at a connector to a terminal end of coiled tubing, the tool having a tubular extending from the connector to a heating head having a heater, a fluid passage extending from a discharge port in the tubular through the connector into the coiled tubing, and a one-way valve in the fluid passage between the discharge port and the connector, and a power cable electrically coupled to the heater and extending through the tubular, the connector, and the coiled tubing, to an electrical power source.

Abstract: A system and process relating to well fracturing and stimulation operations are provided. The system and process allow for fracturing multiple zones in a wellbore. The system and process provide for introducing a fluid through a plurality of spaced-apart sleeve assemblies wherein each sleeve assembly can be in an operable state which allows the sleeve assembly to be open or closed and can be in a non-operable state which prevents the sleeve assembly from opening or closing.
