...Conclusions A new MEG sensing system, the AquaWatcher from OneSubsea, was evaluated by employing our newly-constructed HyJump flowloop. The following are key outcomes of this project: (i) The AquaWatcher noise baseline was found to be approximately 2 wt% MEG, (ii) In presence of hydrate...

... Abstract Dual function hydrate inhibitor (DFI) is envisaged to provide superior inhibition performances for controlling hydrate formation in comparison to conventional thermodynamic (THI) and kinetic hydrate (KHI) inhibitors. In this work, the performance of DFI was evaluated in high pressure...

Pipeline Hydrate Formation is the biggest operational challenge, which frequently disrupts the production of some of the high producing gas...

... and 50 L/min, respectively. The flow regime of the initial gas-liquid flows is determined to be turbulent bubbly flows. Transformation of vapor methane into solid methane hydrate is made by elevating the system pressure up to the super cooling condition through water injection. The detail emulsification...

... Abstract Water condensation and/or hydrate formation at the top of pipelines are serious design/operation consideration in pipelines with stratified flow. Water condensation could result in top of the line corrosion, in particular in sour gas systems. Hydrate formation is believed to be another...

... behaviour of CO 2 -rich systems. The hydrate-forming conditions are modelled by the solid solution theory of van der Waals and Platteeuw. The reliability of the thermodynamic model was evaluated using vapour – liquid equilibrium data. CO 2 is a partially polar compound present in many hydrocarbon...

... including shallow water flow and gas Hydrates are key to designing cement slurries that can meet deepwater specifications and provide required zonal isolation. This paper will discuss the real challenges faced during the cementation of critical surface casing for a major operator in India. The maximum...

... Abstract Hydrate management during transient operation of subsea flow lines has been identified as one of the greatest challenges for deep water O&G production. Experiments using natural gas and de-ionized water were conducted in a laboratory flow loop (1" diameter and 40 m length...

... Abstract Gas hydrates are group ice-like crystalline compounds, which form through a combination of water and suitably sized guest molecules under low temperature and high pressure conditions. The important properties of hydrate are very high gas to solid ratio, 1m 3 of hydrate may contain up...

... Abstract Generally, the most economical material for construction in oil and gas pipeline systems is carbon steel. Besides the safety and environmental issues, downtime caused by corrosion related failures and hydrate-induced blockages in pipelines can be costly to the operator. Asset integrity...

Conclusions The hypothesis that hydrate formation can achieve sufficient dehydration for carbon steel pipeline material to be used with glycol has been proven. (A Curtin University PhD student is currently researching the potential for a subsea...

... the infrastructure, the experts try to modify the form of natural gas into a more transportable manner. They invented that natural gas can be transformed into its hydrate form which is solid and easy to be transported. This form is called Synthetic Natural gas Hydrate (SNGH). SNGH is the hydrate form of natural gas...

... This paper presents a case study of a typical Indonesia deepwater gas/condensate field. The objective is to present some of the operational challenges and illustrate how a preferred strategy for managing these challenges is selected. The strategies for managing hydrates and the wax deposition...

... Abstract With the petroleum industry endeavouring to develop oil and gas fields in deepwater and to increase its activities in onshore arctic environments, greater emphasis should be placed on quantifying the hazards to drilling operations posed by gas hydrates. In spite of gas hydrate-bearing...

... Abstract In order to secure future energy needs, exploration for hydrocarbon reservoirs occurs increasingly in Arctic and Deep Water Environments. These two drilling environments establish temperature-pressure conditions that are favorable to gas hydrates. Gas hydrates are crystalline complexes...
