Abstract

visio conference ; online conference; International audience; This study proposes a simulator of the growth kinetics of gas hydrates occurring in the porous-scale, its agglomeration in the interparticle- and particle-scales, coupled to gas-(water-in-oil) slug flow hydrodynamics and heat transfer in the macro-scale. Closure is obtained from slurry apparent viscosity models, droplet size models, and specific slug flow correlations for translational velocity, slug aeration and slug frequency. The results capture four types of systems, namely active surface-, dissolution-, heat transfer- and pressure drop-limited systems. This paper discusses when and why each type of system occurs.

Abstract

Carlos Lange Bassani a remporté le prix du meilleur poster lors de la journée scientifique du CODEGEPRA 2017; International audience; The high pressure and low temperature conditions commonly found in offshore oil & gas production scenarios favor the formation of gas hydrates, which may block the production pipeline causing several revenue losses. Gas hydrates are crystals formed by the imprisonment of gas molecules (e.g., lighthydrocarbons) in a cage of hydrogen-bonded water molecules. The multiphase flow inside the pipelines (composed by oil, gas, sand and water with salt) determines the interfacial surfaces between the phases (e.g., oil & gas, oil & water), which by their turn are essential to predict the order ofmagnitude of each competing phenomena on the hydrate growth kinetics. The present study couples gas absorption by the bulk, gas diffusion and water permeability through the hydrate shell with the phenomena of particle core pressurization and crystal integration processes either in the inner and outer particle surface for predicting gas hydrate growth in water-in-oil emulsions. The model results in three ODE’s for the inner and outer growth radius and for the bulk gas concentration. The initial size of the hydrate particles come from the radius of the water droplets, estimated via the turbulence vs. surface energy criterion of Hinze. Preliminary implementations show that the model captures the mass transfer limitation due to the hydrate shell growth, which is represented by the asymptotic trend of the amount of gas consumed over time. Future work shall be done in order to couple the present model with pressure and temperature predictions over the production pipeline (from multiphase flow calculations), to measure the necessary closure parameters of the model (e.g., constant of proportionality of the crystal integration process, gas diffusion and absorption coefficients, etc.) and to validate the model against experimental data.

Abstract

Poster session : Flow Assurance; International audience; Gas hydrates is a significant part in the portfolio of topics covered in the flow assurance of oil and gas production. Major advances have been made in understanding hydrates formation in multiphase system, which has enabled a gradual shift in practice to hydrate management from avoidance. In hydrate management, the challenges for hydrates also shift from formation to transportability, which is significantly a much more complex problem due to the hydrodynamic of flow and dispersion of the phases. As such, understanding the interplay of hydrates and multiphase flow is critically important, especially in quan tifying how hydrate formation is determined by the flow characteristics and how the flow regime is altered by the presence and distribution of hydrates. This contribution explores the limited knowledge in this area and expands on the experimental and modeling areas which must be studied to develop the knowledge and tools for effective hydrate management. Some of the key areas to be discussed include hydrate distribution in flowlines and among phases, hydrate deposition, hydrate non-equilibrium kinetics, hydrate accumulation, flow regime, and phases dispersion.
