Abstract: A method of arranging synchronization of databases, the method comprising the steps of establishing a transport layer connection for synchronization between a first and a second device which synchronize databases. During initialization of synchronization a first update identifier, which is stored at least in the first device and describes the latest synchronization event the devices have performed in the databases, and a second update identifier, which is defined by the first device and describes the present synchronization, are transmitted from the first device to the second device. The second update identifier is stored in the first and the second device. The contents of the first update identifiers stored in the devices are updated in the first and the second device if synchronization has been performed and after this said transport layer connection has been ended substantially properly.

Abstract: A method and apparatus for determining the location of stuck pipe are provided. In one embodiment, the method includes the step of attaching a free point logging tool to a working line such as a slickline or wireline. The free point logging tool has a freepoint sensor and, optionally, an acoustic sensor. The freepoint sensor acquires magnetic permeability data in a string of pipe, while the acoustic sensor acquires acoustic data in the pipe. Two sets of data for each sensor are acquired - - one in which the pipe under investigation is unstressed, and one in which the pipe is stressed. The first set and second sets of magnetic permeability data are compared to determine the stuck point location for the pipe. The first and second sets of acoustic data are compared to determine the nature in which the pipe is stuck.
