The part of Blackie is played in the episodes by veteran TV and film actor Denver Pyle, best known for his television roles as Uncle Jesse Duke of CBS-TV's The Dukes of Hazzard, and also as Briscoe Darling on The Andy Griffith Show in the 1960's.
J.R., was ever grateful to Blackie for helping him find oil in the town where Jock had his first strike; He made sure of Blackie, his nickname coming from the claim, as J.R., when talking to daughter Meg (Chris Weatherhead) "When Blackie sniffed out oil, everybody was covered with crude oil as soon as they started drillin'!", was well compensated by paying royalties to him out of his own pocket, as he then seeks his expertise on another strike at a drilling site. 
When he meets up with Meg, who now runs Blackie's company, Callahan Oil, he must go to a low-security prison to bail him out of jail to get his help, but first had to persuade the irasible Blackie, who must have got in some brawl or disturbance that got him in the pokie in the first place, to leave as the warden, Warden Beckman (Troy Evans) says that he "liked it there", and would always do something, such as throwing a brick through a window in order to extend his stay there.
