... Abstract. A new predictive model for hydrate formation kinetics that captures the porous structure evolution in time is coupled with a multiphase flow mechanistic model. It is assumed that the hydrate particles behave as sponges, related to hydrate formation under flow shear. The multiphase...

... with a one-dimensional multiphase flow simulator. The hydrate formation and particles size are handled with a Population Balance framework and a more classic framework. For simulations of hydrate-forming oil-dominated flows in an experimental flow loop, the hydrate cut, subcooling, slurry viscosity and water...

... 1 INTRODUCTION Particle transportation is a common flow assurance problem occurring in oil and gas pipelines. When production takes place in oil and gas wells, oil, gas, water and impurities are produced and transported through the pipeline. Common impurities produced in oil and gas wells...

... ABSTRACT The present work shows the methodology followed in order to implement and validate a sand transport model within a commercial multiphase simulator. Several published correlations for critical velocity, i.e. the velocity required to maintain suspended the sand particles, were...

..., such as Minimum Transport Velocity, and Solid Transport Velocity, etc. (Yan (2010)). Oroskar and Turian (1980) used the term "critical velocity" as the velocity that marks the transition from the settling of solid particles at the bottom of the pipe to the full suspension of the particles in the flowing fluid...

ECT is a first of its kind erosion control technology to reduce metal loss due to sand erosion by redistributing sand particles in a flow field. CFD was used for designing the test rig and the technology itself. This paper will highlight the process...

The results from the simulation are compared to experimental data for several conditions. A simplified erosion prediction model has been also developed to predict...

... ABSTRACT A continuous numerical flow model is introduced. The flow consists of a liquid and a sediment phase. The sediment is modeled as a continuum and consists of several particle fractions and sizes. The momentum equations are solved numerically with the fractional step method...

... ABSTRACT Sand management, as a part of flow assurance processes, is attracting more interest due to recent oil field development with sand production. One key interest is to incorporate the pipeline design with the ability to handle sand particles in different pipe geometries (horizontal...

... ABSTRACT A new method for producing a transportable hydrate slurry has been tested in small scale laboratory equipment. The idea is to use robust nucleation seed particles that can follow the flow and be available when hydrate conditions arise so that hydrate preferentially forms...

... ABSTRACT In this paper, we propose a one-dimensional multi-mixture model to simulate sand transport in stratified gas-liquid two-phase pipeline flow. The approach assumes that the flow consists of a sand bed and two mixture layers: liquid-continuous with dispersed particles and gas-continuous...

Thanks to a fractal approach, an effective size of hydrate aggregates can be deduced from the apparent viscosity, once all the other physical phenomena...

To be able to predict the hydrate particle size distribution and the hydrate coat behaviour, a population balance equation...

The difficulty is compounded if the particles are entrained in multiphase flow. Researchers have developed models to predict erosion resulting...

Both these effects are due to the skewed particle and velocity distributions predicted by the cross sectional model. flow assurance...
