  • Patent number: 9316097
    Abstract: A system and method are provided for recovering bitumen from a bitumen reserve. The method includes recovering bitumen from an alternative pay region in the bitumen reserve via gravity drainage using an inclined horizontally drilled well drilled from a drainage pit upwardly into the bitumen reserve. The drainage pit has been excavated into an area of an underlying formation that is, at least in part, adjacent to and underlying the bitumen reserve. The alternative pay region includes a region unsuitable for recovering bitumen by surface mining or by in situ recovery using wells that produce bitumen to ground level above the alternative pay region.

  • Publication number: 20150377385
    Abstract: A method of abandoning a pipeline during subsea pipelaying from a pipelay vessel includes suspending the pipe string from a tendon element of an abandonment string and engaging further tendon elements to an upper end of the abandonment string while lowering the pipe string to a handover depth. At the handover depth, tension is applied via a wire to the top of the pipe string at an acute angle to the launch axis. This deflects the pipe string from the launch axis into axial alignment with the wire to transfer the weight load of the pipe string to the wire, whereupon the abandonment string can be decoupled from the pipe string. Recovery of the pipeline from the seabed can be effected by a reverse process.

  • Patent number: 9135340
    Abstract: A system for providing relevant documents from a plurality of databases, including a search module for receiving at least one search expression, at least one managed database including a plurality of managed documents and a plurality of search records, each search record including at least one prior search expression associated with at least one of the plurality of managed documents, a plurality of unmanaged databases including a plurality of unmanaged documents, wherein the search module queries the managed database to determine at least one of the search records corresponding to the received search expression, and wherein the search module retrieves at least one of the managed documents associated with the determined search record. The search module may further query the plurality of unmanaged databases to determine one or more unmanaged documents corresponding to the at least one search expression and store the unmanaged document in the managed database.

  • Patent number: 8954443
    Abstract: The present invention is a method for performing a multi-protocol scan of a NAS system by a storage virtualization system to create a multi-protocol file index. Current NAS systems may utilize two protocols, CIFS and NFS. Storage virtualization systems migrate, redirect or synchronize data between a primary and a secondary NAS. Present storage virtualization systems are designed to work with NFS or CIFS systems, but not both. The present invention enables a storage virtualization system to simultaneously or near-simultaneously operate using NFS and CIFS protocols. The present invention also provides for a multi-protocol scan of a NAS device to ensure that all data files and data file attributes are recognized and preserved during storage virtualization.

  • Patent number: 8950977
    Abstract: An elongate sling section is disclosed. The elongate sling is cooperable with like sling sections to form a sling for use in abandonment or recovery of a pipeline. The sling section includes end-pieces at five opposite ends and complementary connector formations associated with each respective end-piece. Each connector formation is cooperable, in use when forming a sling, with a complementary connector formation of a neighbouring sling section in the sling. The sling section further includes a tensile load-bearing sling element extending between the end-pieces and a sleeve around the sling element.
