The Vancouver native is two years removed from a 50-point season, put together during his first season in Edmonton in 2016-17.
Edmonton will retain 12.5 percent of Lucic's remaining contract, dropping his cap hit with the Flames from $6 million to $5.25 million.
Neal was made expendable because of a high priced contract that will see him make $5.75 million per season over the next four years.
He brings solid leadership to the Oilers with a resume that includes scoring 11 points in 20 games in helping lead the Golden Knights to the 2018 National Hockey League finals where they lost to the Washington Capitals in five games.
Neal was originally chosen in the second round of the 2005 National Hockey League draft by the Dallas Stars. In 63 games, he managed just seven goals - the first time in his career he failed to score at least 20 in a campaign - and finished with 19 points, all the while averaging a career-low 14:57 in ice time.
Neal scored seven goals last season, the first time in his 11 National Hockey League seasons he failed to score at least 20. If the Oilers were to buy out Neal next June during the buy out window, he would come at a cap hit of $1,916,667 for the next six seasons.
