Injecting excessive or inadequate amounts of chemical can cause costly waste and greatly reduce the effectiveness of your chemical application strategy. Improper chemical rates can also cause both surface and downhole problems that can lead to costly cleanup, repairs and downtime.

To consistently inject the desired chemical at the desired rate and volume specified by your chemical applications specialist.

Installation of the DCIV-5000 injection valve will allow you to maintain a desired level of chemical in the capillary string. The crack pressure of the valve can be easily adjusted on site prior to installation. The valve then opens and closes at its set pressure releasing the desired amount of chemical into the well regardless of the bottom hole operating pressure.

Downhole chemicals, gasses and fluids are all capable of backing up into the tubing string. These can be highly corossive, caustic, high in chlorides and acidic, all of which can have adverse affects on your tubing string.

To prevent harmful well components from entering the capillary string.

The DCIV-5000 contains a double safety when it comes to the prevention of back flow. The injection valve acts as the first line of defense requiring several times the set pressure to move the dart off of it's seat when the force is applied in the reverse direction. The DCIV-5000 then contains a traditional style dart and seat style check valve that insures no well contaminates can enter the tubing string.

Free flow occurs when the bottom hole pressure drops below the hydrostatic column pressure, allowing chemicals to flow freely through a conventional check valve until the differential between the bottom hole pressure and the hydrostatic column pressure becomes great enough to stop the chemical flow. If the downhole pressure drop is great enough it can create a siphon effect and dump the entire batch of chemical at one time.

To avoid either free flow or the siphoning conditions from occurring regardless of the downhole operating pressure fluctuations, thereby, reducing a costly waste of chemicals.

The DCIV-5000 eliminates these problems by only allowing chemical to inject into the well when the set crack pressure of the valve is exceeded. The fluctuating downhole operating pressures have little to no effect on the valve's set pressure, allowing the valve to be set based only on the well depth (hydrostatic column weight).

Dirty chemical or small pieces of debris from the chemical pump can be a source of several of the above stated problems.

To remove any particulate large enough to create a possible problem with either the capillary string, the down hole check valve or the injection valve.

The HPF-3000 high pressure chemical filter is designed to be installed immediately after the chemical pump. At only 2.5 lbs., this filter is small enough to be set inline while maintaining an incredible 3000 psi. pressure rating.
