... of the couplings was found to be normal. The journal bearing pads had minor scratches. The thrust bearing pads were not affected by the failure. Alignment readings were found to be normal. However, residual unbalance was found on the rotor. This residual unbalance was found to be the root cause of the tripping...

... Abstract Marine turbine bearings are very susceptible to failures through number of different mechanisms such as wear, fatigue and mechanical damages due to the conditions it operates in. The failure of this particular thrust bearing lead to the whole turbine being shut down as a result sizing...

... Abstract Positive identification of a water bearing interval is crucial to evaluating hydrocarbon bearing reservoirs in a well. Accurate estimation of formation water resistivity is also critical for proper computation of reservoir parameters used in hydrocarbon resource assessment...

... challenges include deep/hot holes, high mud weights, harsh mud chemistry, high temperatures and applications with less than desired solids control. These hostile down-hole environments contribute to bit damage and can often lead to the failure of moving components, specifically rollercone bit bearings...

The first element describes the key enabling technologies of DGC, a low loss electrical power delivery system and the application of gas bearings to a downhole rotating assembly. The second element of the paper describes the verification philosophy being...

...-bearing sands. This correlation is used to predict Vp/Vs over the whole logged interval. A large difference between predicted and measured Vp/Vs indicates the presence of gas. Since gas is very compressible, the effect is noticeable even at very low gas saturations, i.e., in gas reservoirs that have...
