| A coring system and method enable a single-trip operation for setting a deflector assembly, deploying a coring assembly and obtaining a core sample from a borehole drilled in a wellbore. The coring assembly has a barrel with a bore for collecting the core sample and has a coring bit coupled to an end portion of the barrel. The deflector system is arranged to deflect the coring bit into a side wall of the wellbore to drill the borehole therein. The deflector system includes a deflector and a collar. The collar, coupled to the deflector, restricts upward movement of the coring assembly relative to the deflector assembly. The collar may also be used as a retrieval device to engage the coring assembly and permit removal of the coring assembly and the deflector assembly as well as the core sample after the core sample has been obtained. | ||||||
