20120298245, Nov 29, 2012

Filed:

Jan 25, 2011

Appl. No.:

13/575428

Inventors:

Michael Hosokawa Dupre - Houston TX, US
Donald Christopher Nelson - Cypress TX, US

Assignee:

SHELL OIL COMPANY - Houston TX

International Classification:

F16L 3/00
B23P 17/00

US Classification:

138106, 137 1501

Abstract:

A method of making a connection in a subsea pipeline, comprising lowering a foundation over a section of the pipeline; cutting the out a section of the pipeline to form an end of a first pipeline and an end of a second pipeline; connecting a first hub to the end of the first pipeline; connecting a second hub to the end of the second pipeline; connecting a first port to the first hub; connecting a second port to the second hub; and connecting a jumper between the first port and the second port.

International Classification:

F16L 1/24
E21B 17/01

Abstract:

A method for controlling buckling in subsea pipelines involves identifying spaced-apart sections of a subsea pipeline suitable for controlled lateral buckling. Sets of buoyancy modules are installed at each spaced-apart section and are selected to support the spaced-apart sections of the subsea pipeline in a neutrally buoyant condition at the seafloor when the subsea pipeline is in service. Any buckling caused by thermal expansion of the subsea pipeline is distributed to two or more of the spaced-apart sections, causing the two or more spaced-apart sections to deflect laterally along the seafloor outwardly from an initial as-laid position.

International Classification:

G01V 99/00
G06T 17/05
G06T 7/50
G06Q 10/04

Abstract:

A method and a system for modeling a three-dimensional geological structure. A method may comprise selecting input data from well measurement systems, seismic surveys or other sources, inputting the input data into an information handling system, building a quotient space, projecting constraints to the quotient space, constructing depth functions on the quotient space, trimming against a fault network, and producing a three-dimensional model of horizons. A system may comprise a downhole tool. The downhole tool may comprise at least one receiver and at least one transmitter. The system may further comprise a conveyance and an information handling system. The information handling system may be configured to select an input data, build a quotient space, project constraints to the quotient space, construct depth functions on the quotient space, trim against a fault network, and produce a three-dimensional model of a geological structure.

International Classification:

F16L 3/18
E02D 5/22

Abstract:

A system and method for securely cradling a subsea pipeline is claimed that lands on one side of the pipeline, is embedded into the sea floor, reaches under the pipeline, positions the cradling structure, and then lifts the pipeline. The system typically comprises a gravity driven pile based device, comprising a pile tower, a roller carriage assembly, and a jacking assembly that engages the roller carriage assembly and pile tower rails.
