One of the management strategies in handling drill cuttings is the use of low temperature thermal desorption technology which goal is to produce oil-free solids for disposal by distilling off the oils from the cuttings and recovering the oil to be reused as drilling fluid. A retort analysis was carried out on the oily and cleaned cuttings to determine the percentage of oil and water content at the temperatures of 350°C and 500°C.The percentages of oil in the oily cuttings are 11.2, 19.4 and 9.6 at 350°C and 13, 14.6 and 23.0 at 500°C and the percentages of oil in the cleaned cuttings were 0.24, 0.21 and 0.23 at 350°C respectively. The concentrations of chlorides and heavy metals are 820 and 0.002mg/l respectively. The result obtained meets the regulatory requirement of oil on cuttings (OOC) of less than 1% by weight, eliminating future environmental liabilities. This study reveals the efficiency of TDU process in the recovery of oil from drill cuttings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
