Abstract:
The development of petrochemical refinery industries has resulted in increased production of petroleum sludge and its disposal, which poses a risk of introducing hazardous elements into the environment. Eliminating petroleum sludge from storage, processing, transportation, and pipeline systems were always a major problem for the oil and gas industry. Today there are an estimated 60 million tons of petroleum sludge produced annually. Statistics also show that one ton of oily sludge is produced for every 500 tons of crude oil processed. Therefore, the petroleum industry requires protected and en

Abstract:
Abstract Gasification and combustion performance of petroleum coke–water slurry (PCWS) can be enhanced by the addition of sludge. In this study, we have mixed three types of sludge with petroleum coke to form petroleum coke–sludge slurry (PCSS) and analyzed the effects of surface chemistry and structure of the sludge samples on the rheological properties of PCSS. Results show that the surface of petroleum coke particles is strongly hydrophobic, while the surface of sludge particles is hydrophilic. The sludge particles primarily consist of oxide and mineral salts, while petroleum coke particles

Abstract:
Abstract Sludge formed downhole in the production interval can be classified into crude oil-based or mud-based sludge. Sludge obstruction may result in partial or total loss of well productivity. Oil-based mud is commonly used in drilling of the pay zones in sandstone formations as a less/non damaging fluid. Oil-based mud typically contain emulsifier, viscosifer and other additives including polymer blend and calcium carbonate to serve different functions. Presence of emulsifier may increase emulsion tendency upon interaction with downhole environment. The resulting emulsion might be tight to

Abstract:
Abstract Sludge formation in oil wells results in near wellbore flow restriction or causes damage to electric submersiable pumps (ESP), thus, reducing their lifetime and causing operational upsets. Prevention and cleanout solutions of such deposits require understanding of sludge characterization and potential formation mechanism. The objective of this study is to present typical types of oilfield sludge and propose a systematic testing protocol to properly characterize organic/inorganic depositions. Examples of typical oilfield sludge deposits were obtained for the study that either organic,
