Abstract:
ABSTRACT The chemical composition and physical properties of a crude oil determine the behavior of the oil and the way its properties will change when the oil is spilled at sea. Reliable knowledge of the oil's behavior will enable the most effective countermeasure techniques to be used in a spill situation. A diverse range of crude oils is coming into production in the North Sea. The weathering behavior and chemical dispersibility of three very different crude oils—Troll (naphthenic), Balder (asphaltenic), and Nome (waxy)—have recently been thoroughly investigated through bench- and meso-scale

Abstract:
The various methods for handling waxy crude oils at temperatures below the pour point have been difficult to assess quantitatively owing to the lack of reliable measurement techniques for properties such as the non-Newtonian viscosity and yield stress. Research undertaken at The University of Melbourne has been aimed at the development of reproducible measurement techniques for laboratory scale rheometers and, in so doing, has provided an understanding of the rheology of waxy oils that is applicable to the design and operation of waxy oil pipelines and handling systems and in understanding the

Abstract:
The crude oils exploited in oilfields are mainly high-wax crude oils. Paraffins precipitate, crystallize, and form a three-dimensional network structure, when the temperature falls below the Wax Appearance Temperature (WAT), which decreases crude oil fluidity. This poses huge challenges to oil exploitation and transportation, as well as cost control. To date, the addition of chemical pour point depressants has been a convenient and economical method to improve low-temperature fluidity in crude oils. This article reviews the types of pour point depressants of crude oil and their performance mec

Abstract:
Waxy crude oils are highly non-Newtonian fluids known to cause pipelining difficulties because their rheological properties are strongly affected by paraffin crystallization. On the basis of experimental data, a physical model has been developed to describe the behavior of these crudes. The corresponding mathematical problem has been studied in planar geometry proving the existence and uniqueness of a classical solution. A condition on the pressure gradient has been found ensuring that the system do not come to a complete stop in finite time.

Abstract:
ABSTRACT Small- and mid-scale laboratory tests were undertaken to investigate the behavior and cleanup of spills of waxy crude oils at sea. The results indicate that the behavior of such oils is very different from that of conventional oils. This difference is likely due primarily to the precipitation of waxes, asphaltenes, and other unknown resinous compounds as the oil evaporates or as environmental temperatures drop. Thus, the oil spreads, evaporates, and naturally disperses very slowly, or in the extreme, even gels into a semisolid mass. Waxy oil spills can be expected to survive on the se

At the time, the limits in rheological instruments were such that they never actually measured the elastic-limit, a key fundamental property.

The current study concerns a recurrent problem in the oil industry when dealing with waxy crude oils in offshore fields. When a waxy crude stays static in the seabed for any reason, it cools down below the wax appearance temperature (WAT). Hence, crystals of wax appear in the fluid. These wax crystals form a crystalline structure. The strength of a crystalline structure rises with time. What also rises with time is the minimum pressure necessary to restart the flow. When designing subsea structures, engineers assume that flow restart will occur when the pressure is sufficient to overcome a thr
