Description
Summary:With case studies, the practices, problems, and prospects of handling waxy crude oils in Nigeria are discussed. Using a rotational viscometer, the temperature dependence of Theological properties and thixotropy of these crudes were determined. Suggestions are given on how to improve handling practices. These suggestions include adequate screening and ranking of wax inhibitors, taking into account pour-point depression, viscosity, and yield value. Rheological studies would help in pipeline design and handling methods. A thorough knowledge of the nature of the crude oil at the time of discovery would help in the design of well completion and production facilities to optimize production.
