The fine coded mask imaging system of the hard X-ray/soft gamma-ray (15 keV-10 MeV) IBIS telescope onboard INTEGRAL is particularly suited to the study of these hard X-ray sources, often associated to black holes. IBIS will be able to position most these sources with a great accuracy ( < 1') even from GPS data, thereby allowing prompt optical identification and ground observations to be carried out. Follow up pointed IBIS observations will instead provide detailed spectra in a wide energy band, and high resolution timing informations, to be used to search for gamma-ray lines (of Nova Musca type) and for spectral/timing signatures of radiation mechanism in black hole accreting binaries. In addition IBIS data taken during the GCDE survey will allow to search for faint and distant X-ray Novae of the galactic bulge, which are not easily detected by conventional all-sky monitors but which the GRANAT/SIGMA experience has shown to be an important population of transient sources.
We discuss here the overall strategy which could be implemented in the INTEGRAL mission for detailed study of X-ray Novae, in particular presenting realistic simulations of X-ray Novae observations with the IBIS telescope, but also considering contributions from the other INTEGRAL instruments.
