Patent CA-2810438-A1 (CA)
Inventor: HU SHENG
IPC: C10G65/04
Filed: 2011-06-03
Abstract: A method for producing a lubricating base oil with low cloud point and high viscosity index is provided. The method uses a highly waxy distillate oil having an initial boiling point of 300-460?, a wax content of 5% or more, a pour point of -20? or more and a cloud point of -5? or more as a raw material. The lubricating base oil having a low pour point, a low cloud point and a high viscosity index is produced by pre-hydrorefining, isomerized/asymmetrical cracking and supplementary refining in the presence of hydrogen, with premium naphtha and middle fraction oil being co-produced. The method is characterized mainly in the high yield of heavy base oil, low pour point and the cloud point, and high viscosity and viscosity index of the base oil.

Abstract: Systems and methodologies are described that facilitate supporting multiple access modes for a base station in a wireless communication environment. The base station can leverage hybrid, closed, or open access mode. A whitelist of a mobile device that successfully registers on the base station can be selectively updated to include a CSG ID of the base station (708). For example, the CSG ID of the base station can be added to the whitelist when the base station operates in closed access mode, while adding the CSG ID can be skipped when the base station operates in hybrid access mode. According to another example, the CSG ID can be selectively added based upon a received accept cause value. Additionally or alternatively, a CSG ID and an access mode indicator can be transmitted from a base station to a network node for implementing access control and/or paging optimization at the network node.

Abstract: A method for analysing incoming data, comprising the steps of processing the incoming data in segments to output a sequence of segment types by extracting one or more properties of an incoming data segment and forming an Unknown Property Vector for each segment of data in the incoming data, and processing the sequence of segment types to identify events in the incoming data. The sequence of segment types is determined, for each segment, by reference to a set of Reference Property Vectors that are relevant to the Unknown Property Vector. This may involve application of first and/or second and/or further functions to identify at least a first subset of Reference Property Vectors that are relevant to the Unknown Property Vector. Alternatively, a logistic regression algorithm, derived using clustering or classification methods for identifying candidate vectors, may be used.

Abstract: A well that has a plurality of sliding sleeves used to originally fracture multiple zones with balls of increasing size dropped on balls seats to sequentially open ports for fracturing in a direction toward the well surface is refractured. The method involves using a bottom hole assembly (BHA) that has a fluid motor driven mill that mills out ball seats and has with it a ported sub and a resettable packer. Once the lowermost ball seat is milled out a ball is dropped into the BHA to isolate the fluid motor and open a ported sub below a resettable packer. The dropped ball also enables a collet to latch an open sleeve to give a surface signal that the BHA is located properly for packer deployment so that the refracturing can begin through the coiled tubing string that can support the BHA or in a surrounding annular space.
