Following the 2022 Russian invasion of Ukraine in February 2022, Geybel was banned by LEN indefinitely from their competitions starting on 3 March and by FINA from their competitions effective at least from 21 April to 31 December 2022 as a means of keeping all Russians and Belarusians in-check by the international governing bodies (LEN - Europe; FINA - World). The times he and other Russians swam at other competitions during the year FINA did not count towards world records nor world rankings.

On 13 August 2015, as part of the year's FINA World Masters Championships held at the Palace of Water Sports in Kazan, Russia, Geybel set a new masters world record in the long course 50-metre breaststroke for the 30—34 age group with a time of 28.24 seconds.

Geybel split a 25.96 for the breaststroke leg of the 4×50-metre medley relay in the prelims heats, helping the prelims relay of him, Stanislav Donets (backstroke), Aleksandr Popkov (butterfly), and Evgeny Sedov (freestyle) set a new world record in the event at 1:32.78 and advance the relay to the final ranked first overall.

Swimming the breaststroke leg of the 4×50-metre medley relay, he helped the finals relay achieve a time of 1:33.86 and earn the silver medal in the race, splitting a time of 26.47 seconds.

In April of 2008, at the 2008 World Short Course Championships in Manchester, England, Geybel started competition in the 100-metre breaststroke where he placed thirteenth in the semifinals with a time of 59.48 seconds, just two spots behind Ryan Lochte of the United States, and did not advance to the final of the event. For his second event, Geybel ranked seventeenth in the prelims heats of the 50-metre breaststroke with a time of 27.57 seconds and did not advance to the semifinals.
