Water Injection Valves.

All,

I am currently looking at the design of a subsea water injector well here in the North Sea. The well itself will be sub hydrostatic in an overbalance state at all times with a column of seawater.

We are looking into the feasibility of replacing the SSSV with a deepset water injection valve run on a nipple. One of the advantages being that we can potentially reduce the water hammer effect for any unavoidable hard shut-ins of the well with the reflection point set deeper in the well.

I´d be grateful for the forums experience in running injection valves set below the production packer, benefits, history and any track record you can share.

Thanks in advance.
