Gas Lift Issues - Mandrel issues

Gas Lift Issues - Mandrel issues

(OP)
Hello all,

One of our subsea production wells slowly decayed to the point where it stopped taking gas lift. Numerous procedures have been completed including equalising the gas and production annulus and pumping HP N2 to try and lift at higher pressure. We have a proven flow path on the gas side and production side which leads me to think that there is an issue with the injection mandrels however not 100% on what we could do now.

I wonder if anyone has had any similar experience and had any suggestions on what we could do.

Thanks,

AJ
