... on the subsea and topside facilities required to enable an operational philosophy change. This change of the operational philosophy appears feasible, using either timely depressurization or Low Dosage Hydrate Inhibitors (LDHI) as well as a film building corrosion inhibitor in the system.

... deposition within the wellbore and production equipment. The accumulation of deposited wax can decrease oil production rates, cause equipment breakdown, and clog the transport and storage facilities. Currently, different polymeric inhibitors have been utilised in the oil and gas field to mitigate and prevent...

... Abstract In a significant number of oil and gas fields, production chemicals like corrosion inhibitors are continuously injected subsea at the wells and can cause issues with produced water quality. Corrosion inhibitors are generally injected to prevent corrosion in carbon Steel flow lines...

... Abstract Formation of gas hydrates can lead to serious operational, economic and safety problems in the petroleum industry due to potential blockage of oil and gas transmission lines and processing facilities. Thermodynamic inhibitors are widely used to reduce the risks associated with gas...

..., many of which are a direct consequence of the HPHT nature of the field. To mitigate effects of corrosion, the corrosion-resistant alloys deployed in the well completions were extended through the flowlines to the manifold, where inhibitor chemicals could be injected more easily at the lower...

... Abstract Protecting completion and production equipment is of utmost concern during acidizing. The higher the temperature, the more difficult it is to protect metal against corrosion, and the required inhibitor loadings increase with temperature, resulting in greater likelihood of formation...

... Abstract Traditional hydrate inhibitors such as methanol and glycols have been in use for many years, but at today's oil pricesjhe demand for cheaper methods of inhibition will be required. The development of alternative, cost-effective and environmentally acceptable hydrate inhibitors...

... ABSTRACT Chemical squeeze treatment with scale inhibitor has been used extensively to combat downhole scale problems in the Murchison and Hutton fields in the North Sea. Considerable success has been achieved for several years. As the fields mature increasing amounts of water are being produced...
