The young left-back spent the first half of last season at Killie before being recalled by the Stamford Bridge giants.
Shiels, delighted to have Gordon back in the SPL, said: "Chelsea have agreed to let Ben come up and play for us again on loan.
"He left at this time last year and got a fantastic send-off from our fans away at St Mirren. He had a great first half of last season with us - now I hope he can do the same in the second part of this one.
"When he went back, Chelsea put him out on loan to Scunthorpe but there was a problem there after the manager changed.
"They played a different style of football from us. Ben likes it if you can build something up as it gives him the chance to get forward. He's an attacking full-back but if you play back to front like Scunthorpe did he can't get involved in the game."
