  The X-ray burster 4U1850-087, located in the Galactic globular cluster
NGC6712, is an ultracompact binary (orbital period~21 min),likely harbouring a
degenerate companion.The source has been observed at soft gamma-rays several
times with the INTEGRAL satellite,during the monitoring of the Galactic plane,
with an unprecedented exposure time.We analysed all available INTEGRAL
observations, with the main aim of studying the long-term behaviour of this
Galactic bulge X-ray burster.The spectral results are based on the systematic
analysis of all INTEGRAL observations covering the source position performed
between March 2003 and November 2005.The source X-ray emission is hard and is
observed, for the first time, up to 100keV.A broad-band spectrum obtained
combining the INTEGRAL spectrum together with a quasi-simultaneous XMM-Newton
observation performed in September 2003 is well modeled with a disk-blackbody
emission (with kTin=0.8keV) together with a power-law (photon index=2.1).The
2-100keV luminosity is 1.5E36 erg/s (assuming a distance of 6.8kpc).
