Abstract: Methods and apparatus identify downhole equipment and correlate input data with the equipment to improve planning and/or inventory operations. For some embodiments, oilfield equipment or tubular goods such as drill pipe include a shaped recess along an outer circumference for receiving a tag cartridge by shrink fitting. Once tagged, detector system configurations at pipe yards may facilitate logging the presence and location of each drill pipe and correlating specific data, such as inspection data, to each drill pipe. Further, this correlation populates a database utilized to achieve other business functions such as forecasting number of additional drill pipe needed to purchase, invoicing customers according to actual tracked wear/use of the drill pipe being returned, and providing well or job specific drill string population using known history pipe joints.

Abstract: According to the present invention, there is provided a computer system for providing a centralized trading service to one or more trading party sites, the system comprising: a) a service data centre comprising: i) a trading computer arranged to process and communicate trading data and to generate trading ticket data in respect of confirmed trades on the basis of trading data; ii) a data store accessible to the trading computer for temporarily storing trading ticket data records; and b) one or more trading party sites each comprising at least one user terminal running a hypermedia browser application, each trading party site being located remotely from the data centre, and being arranged to communicate with the trading computer over a packet-switched communications network; the system being arranged to present, to users of the terminals, hypermedia user interface components comprising trading data received from the trading computer.

Abstract: A shaft assembly includes first and second shafts that are easily separable. The first shaft has a longitudinal axis, and includes an output end having an axially opening cavity. The second shaft has an end received in the axially opening cavity. A passageway is formed through one of the first and second shafts and is in fluid communication with the cavity for pumping a fluid through the passageway into the cavity between the first and second shafts to axially urge the second shaft out of the cavity.
