Globally, with the increase of oil & gas exploration in conventional and unconventional resources, the output of oil-based drill cuttings (a by-product of drilling operations) has increased significantly. Drill cuttings originate from the drilling process as the bit advances through the bedrock, with drilling fluid carrying rock fragments back up to the rig (Figure 1).[1] Taking the UKCS (United Kingdom Continental Shelf) as an example, every year, more than 80,000 t of oil-based cuttings are produced in offshore.[2] At the same time, oil-based drill cuttings are regarded as hazardous waste by many countries. Not only are they difficult to handle, but improper treatments of them will pose a serious problem to the environment and human health.[3] Therefore, the treatment of oil-based drill cuttings has become a worldwide problem.[4]
