Abstract: A treatment fluid for performing one or more pre-cementing operations in a wellbore can include a base fluid, a viscosifier, and a crushed glass material. The viscosifier can be dispersed in the base fluid. The crushed glass material can be dispersed in the base fluid for performing one or more cementing operations with respect to the wellbore.

Abstract: In a computer network, a method for obtaining information regarding a device in a network, including obtaining said information using Telnet and using said information in the discovery of a network. The method uses a computer program on a computer readable medium loadable into a digital computer or embodied in a carrier wave. Said program comprising of the steps of, in respect of a device, creating a socket; connecting said socket to a Telnet port on said device; if connection was not successful, displaying the device as a generic device on a network map; if connection was successful, reading the login banner data; if the data did not read OK, display the device as a generic device on network map; if the data did read OK, parse the login banner data to obtain type; and use information to obtain device type ID and display relevant device on network map.

Abstract: A method for providing a data set relating to a network by merging a first data set relating to the network at a first time and a second data set relating to the network at a s second, later, time, said first data set comprising data acquired by interrogation of the network and other data, and said second data set comprising data acquired by interrogation of the network, said method comprising: comparing the data in the first data set with the second data set, and updating the first data set to include additional data present in the second data to set which is not present in the first data set.

Abstract: In a network supervising apparatus a program suitable for interrogating, in a network, a selected device of a large number of possible devices in respect of at least one functionality of the device (e.g. topology or sizing) comprising: a plurality of directories of elements, each element comprising a module of program code, each directory having a plurality of elements; selecting from at least one directory those elements which relate to the selected device and the desired functionality; and utilizing the selected elements to interrogate the selected device.
