... an experimental campaign focused on hydrate kinetics and transport in gas-dominant systems. A high-pressure flow loop (40 m length, 2 cm diameter) – called "Hytra" – has been constructed, in which it is possible to study hydrate formation visually and to measure hydrate formation rates and excess pressure drops...

... formation, spending upwards of a week in the hydrate stability zone (at the subcooled/fluid test conditions). Subsequent tests which utilized the memory effect then revealed that the hydrate formation rate reduced in the presence of the surface treatment compared to a bare stainless-steel surface...

... production conditions, as well as testing the performance of chemical mitigation programs. Abstract Gas hydrate formation in natural gas systems and subsea infrastructure can block pipelines and instruments, restrict flow, and lead to safety and environmental hazards in production and/or transportation...

...) hydrate formation, with hydrate growth at the water-oil/water-gas interface under a certain degree of thermal driving force; (3) hydrate agglomeration and deposition; (4) particle jamming and hydrate plugging. Among these mechanisms, film growth, deposition (bedding) can be categorized into hydrate...

... sourced, readily available in commercial quantity and also eco-friendly because it is plant based unlike the N-VCap which is toxic and expensive. It is advised that the local surfactant X be developed as an alternative to the conventional inhibitor for gas hydrate inhibition. gas hydrate formation...

...Abstract Abstract The oil and gas production in deeper water scenarios (e.g. pre-salt) has been increasing due to the growth in industrial production. The exploration fields under more severe conditions is accompanied by concerns about solid precipitation/deposition and hydrate formation...

...Abstract Abstract Hydrates are crystalline water compounds that may form in deepsea pipelines and have the ability to quickly and efficiently plug flow. Given this issue, gas hydrate formation tests have been conducted and reported in a number of published articles. However, most published data...

... Abstract In subsea production operations, wellhead jumpers are one of the subsea facilities more liable to the formation of hydrate blockages during restart operations. To manage hydrate formation and optimize the amount of thermodynamic hydrate inhibitors (e.g. mono-ethylene glycol; MEG...

... Abstract Gas hydrate formation is considered one of the major problems facing the oil and gas industry as it poses a significant threat to the production, transportation and processing of natural gas. These solid structures can nucleate and agglomerate gradually so that a large cluster...

.... An evaluation of the pressure and temperature data suggested that the well had a tubing restriction. This was attributed to hydrate formation and blockage caused by limited methanol injection capacity. A number of attempts were made to induce the well with no success. A subsea intervention vessel...

... Abstract Flow assurance problem of gas hydrate formation in subsea transportation system of crude oil is addressed in this research work. The paper depicts the synthesis and evaluation of propylene glycol quantum dots as low-dosage hydrate inhibitor (LDHI) for preventing / delaying gas hydrate...

... Abstract Quantitative prediction of gas hydrate formation risk is critical for the successful implementation of risk-based approaches to hydrate management in subsea production. Here we use a high pressure, stirred, automated lag-time apparatus and a high pressure acoustic levitator...
