... Abstract An acid stimulation was performed in an ultra-deepwater pre-salt Brazil well to improve its productivity. The formation of hydrate plugs was a critical concern, as the stimulation requires water injection to neutralize the acid, and this well has a high GOR. Even with a risk of hydrate...

... with the study of the pressure-temperature diagram of the production fluid to define the type of solids that could precipitate within the flow lines (hydrates). The heat transfer analysis was determined applying two methods, one numerical and one analytical, the numerical by the computational fluid dynamics (CFD...

... Abstract Blockage of flowlines due to hydrate or paraffin plugging is an on-going issue for the offshore industry. The problem seems to be exacerbated with the higher pressures and colder ambient temperatures as developments progress into deeper and deeper waters. There are many blockage...

... Abstract Years of research and development, as well as field experience has moved the hydrate management philosophy towards less conservative operations. Previously, the standard was to avoid gas hydrates altogether. Now, on the other hand, the industry is more often looking into how to "live...

... Hydrate management, as opposed to avoidance, means allowing hydrates to form, but minimizing the risk of blockage formation, such that hydrates are transported with the production fluids. This strategy is starting to be a more viable approach in industry as a means to lower development...

... investigated using a unique combination of an IPM tool, a topsides process simulator and a PVT tool that can all trace several thermodynamic phases. The formation and dissociation of the gas, liquids and hydrate phases were predicted and tracked throughout the system, subject to the local pressures, enthalpies...

... Abstract A produced hydrocarbon stream from a wellhead encounters formation of solid gas hydrate deposits, which plug flowlines, and are one of the most challenging problems in deep subsea facilities. This paper describes a gas hydrate model for oil-dominated systems, which can be used...
