...CT Well Intervention for Hydrate Plug Milling Hydrate Plug Depth Analysis Before any well intervention job, it is critical to understand the well and any job-specific challenges or risks associated with the job. Identifying the risks beforehand allows the engineering and operational team...

... was carried out when the hydrates were located. MEG was also continuously pumped through the umbilical to the SenTREE* subsea test tree while the CT in hole. To successfully remove the hydrate plugs, the pump rate was increased to 0.8 to 0.9 bbl/min through the high-pressure rotating nozzle. A pressure spike...

..., and operators must remove the hydrate plugs from gas lift and flow lines. As those hydrate plugs are formed under high pressure (1400 to 2800 psi) and low temperature (2 to 4 ºC), exposing them to lower pressures even at the same temperatures will dissociate them. Hence, an operator offshore Brazil has...
