... In the oil and gas production industry, it is well known that formation of hydrate blockages can cause substantial economic impact in terms of deferred production and the costs of remediation. Considering these financial implications and to avoid any potential safety concerns during a hydrate...

.... Moreover, the required inhibitor storage and injection capacity may be far beyond the facility limits when the water production rate is high. In this work, aimed at addressing hydrate associated problems at reduced cost, a method is developed to prevent hydrate blockage with lower inhibitor consumption...

... subsea flowlines, which are flowing with three phase fluids gas, condensate and water. The cold temperatures of the subsea environment pose a flow assurance risk to production, especially for hydrate blockages. The only solution currently being considered to address the risk for hydrate blockages in gas...

... below 39oF will be presented as well as the results. The results include the evaluation of produced fluids with and without the addition of AA-LDHI. These results demonstrate that hydrate formation and the effectiveness of AA-LDHI to inhibit hydrate blockage can be detected at low temperatures using...

... Abstract The Matterhorn field, operated by TOTAL, is located in the Gulf of Mexico, on block 243 of the Mississippi Canyon. It produces oil and gas from seven wells in a water depth of approximately 2800 ft. This paper reviews a hydrate blockage incident which occurred on the Gas Export...

...) and 4 (P-62). Since December 2002 the south area of Module 1A, Phase 1, has been producing by the FPSO-Brasil. The oil presents a strong tendency to wax deposition and gas hydrate blockage. The long flowlines (11-16 km), the low temperatures and high pressures have demanded regular pigging to remove...

... temperature drop will create a real risk of hydrate blockage or wax build-up. As is customary within the oil and gas sector, a conservative approach has historically been taken regarding how close to hydrate formation temperature the system is operated at. When the consequences of hydrate blockage are so huge...

... water eliminated the possibility of scale formation in the flowline. No sign of sand production was observed prior to the blockage. A ROV survey of the line found no visible mechanical damage and a comparison to earlier surveys revealed no significant changes occurred. Hydrate blockage was very likely...

... circulation in flowlines, Provide capability for depressurization and displacement. Depressurization is the principal method of remediating hydrate blockages. The biggest caveat with the best practice listed above regards remediation, since seafloor topography, system geometry, and produced fluids may...

... was "leaked" into a 200-bar (2901-psi) "pipeline" and the resulting hydrate blockage was safely and quickly cleared by pressure reduction on one side of the blockage. The formed blockage contained gas pockets and the measured blockage permeability was low " indicating that reducing the pressure throughout...

... operational procedures carried out in Campos Basin to locate and dissociate gas hydrates plugs in subsea equipment and pipelines. Two cases are discussed.
