Abstract. Fluidized column experiments have been performed, where a 10 cm in diameter and 15 cm high cylindrical sand column was subjected to linear upwards flow of water. The tests were monitored by means of an X-ray CT-scanner. The experiments showed that a change in the flow rate gave rise to a propagating density wave starting …

Sand production is one of the problems that many operators have been dealing with. Sand production can occur based on high flow rates, stress regime, rock geomechanical properties, and completion design. The prediction of sand production is very important since it helps production engineers to come up with sand control strategies. Based on …

Abstract. Sand production is a common problem in the development of oil and gas fields. A large amount of sand production will lead to formation plugging, production reduction or even shutdown of oil and gas wells. Therefore, it is necessary to understand the mechanism of sand production and its hazards, and do a good job in …

Sand production behavior is also studied in laboratories. Oyama et al. (2010) found that the dominant driving force of sand production was water flow rather than gas flow generated by dissociation, and the amount of sand production was influenced by the velocity of the water flow. Jung et al. (2012) suggested that fine particle migration may be …
