Paper presented at the Offshore Technology Conference, May 2–5, 2022
Paper Number: OTC-32023-MS
... Abstract This paper describes a flow assurance method known as "cold flow". The method is suitable for deepwater liquid dominated fields and reduces costs and carbon emissions compared to conventional flow assurance methods by letting hydrate and wax deposits travel as inert solids...

... the fractures ( Faulds and Hinz, 2015 ). Fault reactivations Australian REE deposits are a result of fluid flow through crustal-scale fault zones or structures. The fluids were mineral-rich, and they flowed through the interstices during times of relative tectonic quiescence (Spandler, et al., 2020). Ore...
