Extendable Semi-Clustered Subsea Development System
US Patent:
6059039, May 9, 2000
Filed:
Nov 12, 1997
Appl. No.:
8/968637
Inventors:
John M. Bednar - Kingwood TX
Mark A. Stair - Metairie LA
Mark A. Stair - Metairie LA
Assignee:
ExxonMobil Upstream Research Company - Houston TX
International Classification:
E21B 43017
US Classification:
166344
Abstract:
A subsea production system that facilitates the cost effective development of offshore hydrocarbon reserves. The system includes a template base, a wellhead assembly, a saddle manifold, flowlines, a subsea tree assembly, and a control center. The system facilitates phased development by allowing control over timing for the installation of system components and by providing extendibility to additional wells developed after installation of the system.
Flowline Extendable Pigging Valve Assembly
US Patent:
6182761, Feb 6, 2001
Filed:
Nov 12, 1997
Appl. No.:
8/969131
Inventors:
John M. Bednar - Kingwood TX
Assignee:
ExxonMobil Upstream Research Company - Houston TX
International Classification:
E21B 43013, E21B 43017
US Classification:
166339
Abstract:
An apparatus and a method for extending subsea hydrocarbon flowlines from an initial installation on a template/manifold system to later drilled subsea wells. The extension utilizes a pigging valve assembly which completes a flow path to allow for line cleaning or pigging and is modified by adding a curved flowline connector adaptor to extend the subsea flowlines. The apparatus and method minimizes the amount of equipment that must be pre-installed to provide such flexibility, thus facilitating the ability to defer incremental development decisions.
