We present a catalog of Gamma-Ray Burst X-ray afterglows observed with BeppoSAX, XMM-Newton and Chandra. We use this catalog to compare burst properties and to discriminate their environment. We also use this catalog to compare the X-ray light curves of the afterglows with known distance, and comment the results we obtain.
