Typical analyses of neutrino oscillation violate either conservation of energy or momentum, yet provide an excellent framework for discussion of observed data.
This note reviews how both energy and momentum are conserved in neutrino oscillations if one takes account of the entanglement of the neutrino with its partners in the production process.

The concept of the coherence length for neutrino oscillations is also discussed.
