International Classification:

E21B 29/12

US Classification:

166366, 166345, 166381, 166339, 175 5

Abstract:

A system for supporting multiple-well-site, offshore, hydrocarbon-bearing fields, each well-site has one or more wells. In general, the system first comprises a floating vessel that is relocatable from a first subsea well-site to a second subsea well-site. The system also comprises two separate systems: (1) an operations control system for providing subsea well-site operations such as power and communications; and (2) an intervention system for conducting intervention services to an individual subsea well such as workover services and maintenance services. The operations system may provide control to wells and other subsea equipment at either the first well-site or the second well-site, regardless of the location of the floating vessel. The intervention system may provide workover and/or maintenance to subsea equipment or individual wells at the well-site at which it is located.

US Classification:

166338, 166339, 166344, 166345, 166275

Abstract:

Managing hydrates in a subsea includes a host production facility, a production cluster comprising one or more producers, a water injection cluster comprising one or more water injectors, a water injection line, and a single production line for directing production fluid from the one or more producers to the host production facility. The methods comprise placing a pig in the subsea production system, shutting in production from the producers, and injecting a displacement fluid into the subsea production system in order to displace the hydrate inhibitor and any remaining production fluids in the production flowline and to further move the pig through the production flowline. The method may also include further injecting displacement fluid into the subsea production system in order to displace the hydrate inhibitor and pig through the single production line and to the host production facility.

Abstract:

Method of managing hydrates in a subsea production system that includes a host production facility, one or more producers, one or more water injectors, a water injection line, and a single production line for directing production fluids from the producers to the host production facility. The method comprises placing a pig in the subsea production system, shutting in production from the producers, and injecting a displacement fluid into the subsea production system in order to displace production fluids in the production line. The method also includes applying electrically resistive heat along a selected portion of the single production line to maintain production fluids within the production line at a temperature above a hydrate formation temperature after production has been shut in.

International Classification:

B01D 53/04
B01D 53/26

Abstract:

Provided are apparatus and systems for performing a swing adsorption process. This swing adsorption process may involve passing streams through adsorbent bed units to remove contaminants, such as water, from the stream. As part of the process, the adsorbent bed unit may provide access to the adsorbent material within the adsorbent bed unit without having to remove one or more of valves, conduits and manifolds.

Abstract:

Systems and methods for dehydrating a natural gas stream are provided herein. The system includes a lean solvent feed system, including a line from a topsides facility, wherein the line is configured to divide a lean solvent stream to feed lean solvent to each of a number of co-current contacting systems in parallel. The co-current contacting systems are placed in series along a wet natural gas stream, wherein each of the co-current contacting systems is configured to contact the lean solvent stream with the wet natural gas stream to adsorb at least a portion of the water from the wet natural gas stream to form a dry natural gas stream. A rich solvent return system includes a line to combine rich solvent from each of the plurality of co-current contacting systems and return a rich solvent stream to the topsides facility.

Abstract:

A system and method for separation of liquids and gases within a multiphase fluid are provided herein. The method includes flowing a multiphase fluid into a circular distribution header of a multiphase separation system and separating the multiphase fluid into gases and liquids within the circular distribution header. The method also includes flowing the gases into a circular gas header that is above a plane of the circular distribution header and flowing the liquids into a circular liquid header that is below the plane of the circular distribution header. The method further includes flowing the gases out of the multiphase separation system via a gas outlet line and flowing the liquids out of the multiphase separation system via a liquid outlet line, wherein entrained liquids within the gas outlet line are flowed to the liquid outlet line via a downcomer.
