A system and method for delivering heat to a fluid in a fluid production pipeline. Particles are injected into a line adjacent the fluid production pipeline. The particles include a microencapsulated liquid exothermic phase change material configured to undergo a phase change by solidification and release heat at a selected temperature. The released heat is transferred to the fluid production pipeline.

Protecting a fluid stream from fouling using a phase change material

Embodiments described herein provide a system and methods for protecting a fluid stream from fouling using particles that include phase change materials. In an example, the particles are injected into the fluid stream and release energy at a selected temperature, which may warm the fluid stream.

Protecting a fluid stream from fouling

Processes for forming and sequestering COclathrates in a marine environment are disclosed.

Sequestration of COusing clathrates

A method and systems are provided for injecting a hydrate slurry into a reservoir. The method includes combining gas and water within a subsea simultaneous water and gas (SWAG) injection system. The method also includes forming a hydrate slurry from the gas and the water, and injecting the hydrate slurry into a reservoir.

Injecting a hydrate slurry into a reservoir

A process for managing hydrates and hydrocarbon-based solids in a hydrocarbon stream. The process includes: introducing the hydrocarbon stream into an inlet of a system comprising at least a first cold flow reactor and a second cold flow reactor, each cold flow reactor comprising a heat exchanger and at least one static mixer; directing at least a portion of the hydrocarbon stream to the first cold flow reactor; cooling the portion of the hydrocarbon stream directed to the first cold flow reactor to a temperature less than the hydrate formation temperature, the temperature effective to substantially complete hydrate formation upon exiting the system to form a hydrate and hydrocarbon-based solids managed hydrocarbon stream; directing a lesser portion of the hydrocarbon stream to the second cold flow reactor; and remediating the second cold flow reactor by removing hydrate or hydrocarbon-based solids formed on internal surfaces of the second cold flow reactor. A remediable system for managing hydrates and hydrocarbon-based solids in a hydrocarbon stream is also described.

Process for managing hydrate and wax deposition in hydrocarbon pipelines

An asphaltenes separation system comprising a flocculant feed system configured to add a flocculant to a production fluid to flocculate asphaltenes in the production fluid, and an asphaltenes separator configured to remove flocculated asphaltenes from the production fluid.

Separation of asphaltenes

Methods and systems are provided for producing hydrocarbons from production fluids that have water as an external phase. A method for transporting a hydrocarbon through a pipeline includes injecting water into a production stream at a production center. The production stream includes a hydrocarbon, and the water injection forms a transportation stream that includes a water external phase. The transportation stream is flowed through a transportation line to a surface facility, wherein the transportation line comprises a plurality of static mixers spaced at intervals along the transportation line.

System and method for transporting hydrocarbons

A method, including: performing dual-side depressurization on a hydrate blockage in a subsea flow line, wherein dual-side depressurization includes, reducing pressure on a topside of the hydrate blockage in the subsea flow line by removing liquid from within a subsea riser with a bubble pump that has a first end in fluid communication with the liquid within the subsea riser, reducing pressure on a backside of the hydrate blockage, and concurrently controlling the reduction in pressure on the topside of the hydrate blockage and the backside of the hydrate blockage.
