  Binary star systems represent a significant proportion of the Galactic
stellar population, with X-ray binaries being an important subset of these for
high energy astrophysics. Although hundreds of X-ray binaries are detected in
the Milky Way and beyond, only 12 of these systems are listed in the 4FGL-DR2,
the latest Fermi-LAT point source catalogue. With such a small number
detectable by Fermi-LAT, much is still unknown about the mechanisms by which
these systems emit $\gamma$-rays. We present the method and current status of
our large-scale survey of the X-ray binary population using over 12 years of
Fermi-LAT data, and current catalogues and background models.
