The Black Mass scheduled for 9/21 in OK has now added a Satanic exorcism as one of it's featured events. Now, according to their literature, they will be "exorcising" other religious influences from people. However, traditionally, a "reverse exorcism" usually involves "opening a portal" for Satanic beliefs, i.e. inserting a demon. Since they're invoking a Djinn/demon, I guess they need someone open to being a host. At least that's my take on it!
