摘要: Wax deposition is one of the most expensive flow assurance issues encountered in crude oil production and transportation. It can lead to drastic production loss and ultimately heavy economic losses to E&P companies. Thus, precise prediction for field case is necessary to avoid this issue. Generally, two basic models, Film Mass Transfer (FMT) and Equilibrium Model (EM) are utilized to determine wax mass deposition in the crude oil pipelines. In this study, theoretical wax mass flux is computed based on these methods and compared with a field data point of wax mass deposited in 1.7 km long buried gathering line at Bakrol field, Gujarat, India. For a field flow rate of 100 m3/day in 4 in. pipe (ID= 3.765 in.), the fluid is in laminar flow regime. This contradicts the presumption that only turbulent flow condition prevails in the field. In addition to this, the analysis revealed that actual field wax mass flux for Bakrol field …
