... longer than around 30-40 pipe diameters, while in many oil production fields, slugs can be considerably longer. Consequently, there is a clear need to better understand how and why such long slugs appear in production systems, and in this paper we present results that shed some light on this matter. We...

..., while the mobilization to reach the peak resistance is dependent on the rock berm stiffness. Based on the results from this study, a simplified design chart is presented which provides the lower bound peak lateral resistance for a given pipe diameter under typical rock berm with cover to top of pipe...

... particle shape was included in the correlation. Dimensionless erosion number was calculated for different flow conditions, sand sizes and densities, and pipe diameters. It was shown that the dimensionless groups and their exponents provide insight into the importance of different parameters on erosion...

..., Texas, near Galveston Bay. The study was accomplished using 2.875 and 4.50 inch diameter pipes which were weighted with steel rods to obtain different specific gravities of pipe. A follow up investigation was conducted in the laboratory using pipe diameters of 1.50 and 3.00 inches. The model pipes were...

.... The possibility of a failure due to low cycle fatigue was evaluated. This study indicated that this type of failure should not occur. The ductility of the welds was evaluated and found to be adequate. Oval-ling of the pipe is limited to ± 1% by proper selection of pipe diameter and wall thickness. The radius...
