Long offsets and subsea tie-backs are becoming attractive scenarios for exploration and production of offshore hydrocarbon resources. Flow assurance associated with these field development scenarios is critical. As offshore oil and gas production pushes into deeper water, the risk of hydrate plugging of pipelines and flowlines continues to grow, as does the cost of remediating any such plugs. C...

oil and gas transmission pipelines are critical items of infrastructure in providing energy sources to regions and countries. steel pipes are commonly used which can be subject to both internal and external corrosion. this paper presents an advanced nondestructive inspection technique for detection of oil-gas pipeline corrosion defect. the pulsed eddy current (pec) method has been successfully ...

This study uses the Eulerian-Lagrangian multiphase particle-in-cell (MP-PIC) approach, adopted in computational particle fluid dynamics (CPFD) code, Barracuda VR®, to simulate a cold-flow dual-circulating fluidized bed. The hydrodynamics is simulated using novel segregated which experimental solids circulation rate specified as an input parameter. CPFD predictions of pressures and concentration...

Most studies neglect the presence of thermal cracking reactions in industrial FCC process. Nevertheless, the present work proposes a new model which modified the 10-lumps kinetic model given by Jacob el al. (1976), through to inclusion a new lump named dry gas represent the results of the thermal reactions. Similarly as in the 10-lumps kinetic model, the proposed 11-lumps kinetic model consider...

Method layout of a casting is an important aspect of tooling development. It involves decisions regarding part orientation in mould, parting line, cores, cavity layout, feeders, neck and gating system. An improper method layout leads either poor quality or low yield, which affects the productivity. Method design is mostly carried out manually, using 2D drawing of the cast part. Then tooling is ...

Next-generation sequencing technologies provide an unparallelled opportunity for the characterization and discovery of known and novel viruses. Because viruses are known to have the highest mutation rates when compared to eukaryotic and bacterial organisms, we assess the extent to which eleven well-known alignment algorithms (BLAST, BLAT, BWA, BWA-SW, BWA-MEM, BFAST, Bowtie2, Novoalign, GSNAP, ...

The Honey Lake fault is a major strike-slip fault in northeastern California that accommodates northwest-directed right-lateral shear in the northern Walker Lane. We reexamine the fault’s paleoseismic history and slip rate by evaluating a natural stream bank exposure of the fault and offset terrace riser. Structural and stratigraphic relations within the modern stream cut, radiocarbon ages, and...
