Wellhead ProductIon Choke

Located at the wellhead, where the well-fluid is first extracted from the field, the production choke valve is arguably the most severe service application in the oil and gas industry.

It is essential for providing controlled pressure for downstream processes and needs to handle some of the most difficult fluids and conditions in the entire oil and gas process chain.

With the 100DPC production choke valve, IMI CCI have standardised a product range to maximise valve service life and minimse total valve life cycle costs by addressing the specific severe service concerns which apply to this arduous application, including the following:

Multi-phase fluid which can make accurate sizing difficult

High pressure drop which leads to high kinetic energy levels, which causes erosion, vibration and noise

Potential for high solid content which leads to further erosion issues and potentially clogging

High concentrations of acids (H2S, CO2), chlorides and chemicals which can cause corrosion issues

Long field life with large variation of inlet pressures which subsequently require a wide range of CV’s to maintain flow rates.
