... ( Tomson et al. 2005 ; Masoudi et al. 2006 ). Although KHIs and AAs can be used at lower dosages compared to THIs, they can be used to inhibit the hydrate formation but not to dissolve an already formed hydrate plug. To dissolve an already formed hydrate plug, several approaches can be used...

... layer will not adhere to the wall in a tropical flowline, therefore, a hydrate plug could not form. If this concept is applied to operations of an existing asset, hydrate inhibitor usage can be significantly reduced whilst improving operation efficiency and flexibility. For a new facility design hydrate...

... this simple and efficient device can also be used to dissociate a hydrate plug and eliminate the need for an additional remediation system. A series of reduced scale tests have been performed at the French Petroleum Institute (IFP) in a 2" insulated pressure cell where several hydrate plugs were dissociated...

...., fax 01-972-952-9435. Abstract Hydrate plugs were formed above the mud line in two dry tree oil wells in the Gulf of Mexico. The plugs were formed when trying to open the downhole safety valve with crude to return the wells to production after they were shut-in due to hurricane evacuation. Several...

... is harder to identify. This area will become more important as we develop fields with problematic fluids that need reliable delivery of chemicals. To what subsea component are we referring? We are referring to umbilical tubes. Umbilical tubes have accounted for several hydrate plugs in subsea systems...

... Abstract A subsea bare flowline was plugged with hydrates and waxes causing loss of production. The hydrate plug was successfully dissociated by using the two-sided depressurization method. The wax plug in the subsea flowline was then successfully removed by using a low-cost sustained...

... Abstract Hydrate blockage detection, remediation and removal are successfully applied in a hydrate plug incident in the GOM. A hydrate plug occurred in mid-October 2002 in the Williams Field Services (WFS) owned and operated, 36-mile long, 10- inch gas export pipeline from ChevronTexaco's...
