In order to better study an X-ray binary, multi-wavelength counterparts to the X-ray source must be identified to allow determination of, e.g., distances, energy distribution, and evolutionary phase. For instance, infrared observations can reveal the presence of eclipses, modulations (due to, e.g., orbital periods), variability, etc., allowing us to better constrain the true nature (e.g.: High-Mass or Low-Mass?) of the binary system. In this work we'll discuss the status of an ongoing project in Brazil to identify Infrared counterparts of INTEGRAL X-ray sources. We'll discuss some preliminary results for a dozen (or so) sources and illustrate our search and data analysis with IGR J16320-4751. Future steps of this (and similar) research using the modern 4{\thinspace}m SOAR telescope are also highlighted. This work is partially supported by FAPESP/Brazil.
