An application tool may be coupled to a coiled tubing for performing an operation in a wellbore includes a rigid outer body and at least one flow tube. The rigid outer body includes a first material. The flow tube defines a flow path through the outer rigid body for receiving a corrosive fluid from the coiled tubing after the coiled tubing is coupled to the application tool. The flow tube includes a second material that is corrosion resistant and different than the first material.

Coiled tubing tool flow tube architecture

A technique facilitates mechanical and electrical connection between components. The components may be coupled mechanically by a threaded engagement and electrically by first and second electrical couplers. The first and second electrical couplers may each have a plurality of electrical contacts oriented for linear engagement. The electrical contacts of the second electrical coupler are mounted on a first portion of the second electrical coupler which is rotatably received by a second portion to enable linear engagement of the electrical contacts while rotating the components relative to each other to form the mechanical connection.

Electrical connection apparatus and method

The present invention provides a hydraulically actuated valve adapted for use in downhole well applications that enables control of several hydraulic devices from a single control line. In one embodiment, the valve has a valve body defining an inlet and first and second outlets. A spring-biased piston is located within the valve body. A pressure responsive indexer engages the piston to move the piston between a first and second position. In its first position, the piston prevents fluid flow from the inlet to the first outlet. In its second position, the piston prevents fluid flow from the inlet to the second outlet.
