Provided, in one aspect, is a float for use with a fluid flow control device. The float, in at least one aspect, includes a fluid impermeable exterior, and a base material having one or more cavities positioned within the fluid impermeable exterior, the base material formed using an additive manufacturing process.

Removable trap stations for hydrocarbon flowlines can be implemented as an apparatus. The apparatus includes a multi-phase fluid receiver body and a tank defining an interior volume. The fluid receiver body is configured to couple to a flowline carrying a multi-phase fluid including solids and liquids. The fluid receiver body includes an inlet portion configured to receive a portion of the multi-phase fluid including a portion of the solids flowing through the flowline into the receiver body. The fluid receiver body includes an outlet portion fluidically coupled to the inlet portion. The portion of the multi-phase fluid is configured to flow from the inlet portion to the outlet portion. The tank is fluidically and detachably coupled to the outlet and is configured to receive and retain the portion of the multi-phase fluid received through the inlet portion.

An unmanned production platform comprises apparatus for producing and processing hydrocarbons from a subsea reservoir. A storage vessel is provided in combination with and proximate to the platform, typically just outside the safety zone. The storage vessel provides storage for hydrocarbons produced at the platform and further provides a utility for use at the platform, such as chemical storage, liquid desiccant regeneration and/or seawater treatment. Typically, the unmanned production platform comprises no utilities and all utilities require for production are provided by the storage vessel.

A downhole solids separator having: a plurality of solids separation modules, a production tube disposed therein, one or more limited entry ports in the production tube, placed in each of the modules, an intake port in the lower half of each module opening into a wellbore annulus, the intake port below the limited entry port of the module, a closed chamber for collecting solids, isolated from the well bore, the closed chamber below modules, a solids conveying conduit from at least one module, opening into the closed chamber, an opening restricted to less than the size of the production tube in the conduit near the bottom of the module, an opening in the production tube in the closed chamber, where the production tube opening and conduit opening are configured to effect a drop fluid velocity into production tube to a level insufficient to carry solids into the production tube.

A sink is configured to attach to a bottom surface of a flowline that is configured to flow a mixture of at least two immiscible fluids. One of the immiscible fluids is water. The water is more dense than the other of the at least two immiscible fluids. An outlet formed at a bottom portion of the sink. A valve system is connected to the opening. The valve system is configured to open the outlet in response to the water occupying at least a portion of the sink.

A system (e.g., an oil and/or gas production system) including a filter assembly for separating particulate materials from wellbore fluid. The filter assembly includes a flow cross and a flow bore deflector. The flow cross includes a flow block, a first passage formed in the flow block, and a second passage formed in the flow block. The first and second passages intersect. The flow bore deflector comprises a cap, an extension rod, and a deflector element. The deflector element extends at the intersection between the first and second passages to separate the particulate materials from the wellbore fluid.

A separator for separating constituents of well fluid produced by a well is provided. The separator includes a vessel for receiving well fluid such that a first fluid constituent overlies a second fluid constituent within the vessel, a collection pipe having an opening for collecting a first fluid constituent from the vessel, and a positioner connected to the collection pipe for rotating the collection pipe about an axis to adjust a height of the opening within well fluid in the vessel. A method and system are also provided.
