In the context of oil production, the formation of gas hydrates can lead to the formation of deposits, the clogging of lines and the interruption of oil and/or gas production. Hydrate formation can therefore have a strong economic impact. To ensure production without the risk of production shutdown, different strategies are adopted. A common strategy involves the production outside the hydrate zone by injection of thermodynamic additives (THIs), for example. However, the displacement of hydrate stability conditions by THIs requires the injection of massive doses of additive with high environmental and economic costs. Another production strategy, in the hydrate zone, consists of injecting so-called low dose inhibitors (LDHI): kinetic inhibitors (KHIs) or anti-agglomerant additives (AAs). For deep offshore oil fields, only the injection of AAs is relevant. These additives do not block the formation of hydrates but prevent their agglomeration and disperse the crystals formed in the production fluids. The development of AAs and the validation of their applications on production fields require an in-depth investigation of their impacts on real production systems (dispersion of crystals in pipes, the size of crystals in the continuous phase, the transportability of slurries, etc…).êTo provide a better understanding of the impact of commercial AAs on the formation of hydrates, a multidisciplinary and multi-scale approach was adopted. The formation of natural gas hydrates was first carried out in the laboratory by reproducing oil production conditions with industrial systems under operational conditions with three different AAs. On the macroscopic scale, the slurries of crystals produced under stirring in the reactors highlight effects dependent on the AA used. They impact differently the kinetics of hydrate formation, the rate and speed of crystal growth as well as their state of dispersion. Without stirring, these AAs additives affect the morphology and control the growth of crystals and the phase in which they will grow. A hydrate transfer cell was then designed to sample of hydrate slurries formed in the reactors under conditions close to industrial reality (with stirring, high pressure, low temperature). The transferred hydrate slurries were then analyzed by X-ray microtomography using a method developed during this work. On the microscopic scale, the state of dispersion of the hydrate grains was assessed for all transferred samples and information was obtained on the size of the dispersed hydrate grains, their shape and their sedimentation in the organic phase. At the molecular scale, in-situ analyzes were carried out by Raman spectroscopy on methane hydrates formed in the presence of the three AA additives. These tests highlighted the distribution of hydrates in the organic phases (gas and condensate). Observations by optical microscopy reveal hydrate morphologies comparable to those obtained in the presence of AAs additives in the reactors

Crystallization of hydrates during oil production is a major source of hazards, mainly related to flow lines plugging after hydrate agglomeration. During the petroleum extraction, oil and water circulate in the flow line, forming an unstable emulsion. The water phase in combination with light hydrocarbon components can form hydrates. The crystallization of hydrates has been extensively studied, mainly at low water content systems. However, as the oil field matures, the water fraction increases and can become the dominant phase, a system less known in what concerns hydrate formation. Actually, several techniques can be combined to avoid or remediate hydrate formation. Recently, a new class of additives called Low Dosage Hydrate Inhibitor (LDHI) started to be studied, they are classified as Kinetic Hydrate Inhibitors (KHI-LDHI) and Anti-Agglomerants (AA-LDHI).This work is a parametric study about hydrate formation from emulsion systems ranging from low to high water content, where different flow rates and the anti-agglomerant presence were investigated. The experiments were performed at the Archimède flow loop, which is able to reproduce deep sea conditions. The goal of this study is enhancing the knowledge in hydrate formation and comprehending how the dispersant additive acts to avoid agglomeration. For this matter, it was developed a crystallization topological model for the systems without and with additive. A technique to determine the system continuous phase and a mechanism of the anti-agglomerant action from the chord length measurements were also proposed
