In this work, we present X-ray analysis result of SNR G27.4+0.0 observed by XMM-Newton satellite. Three EPIC detectors are studied comparatively. The spatial and spectral analysis are performed, 0.3-10 keV (all band). In order to define possible distribution of interested abundances soft, medium and hard X-ray images are constructed. NEI (Non-equilibrium ionization) plasma model is used for spectral modelling. Electron temperature (kT), neutral hydrogen column density and ionization time are estimated in the physical range. Flux and luminosity values are calculated for hard (2-10 keV) band. Intrinsic absorption is calculated to be higher than the expected galactic value, due to thick opaque remnant. Based on the analysis results we try to understand the undergoing physical mechanisms in the SNR G27.4+0.0.
