Abstract
The present disclosure is directed to stabilized drill cuttings and a process to stabilize the drill cuttings recovered from drilling a well. The cuttings are mixed with an emulsifier and waxy binding agent and then passed through a centrifuge to separate the stabilized drill cuttings from liquid. The stabilized drill cuttings can then be disposed in a suitable landfill. The stabilized cuttings may also be processed to remove oil and/or bitumen from them, prior to disposal.
