Fault Activation During Hydraulic Fracturing
72nd EAGE Conference and Exhibition incorporating SPE EUROPEC 2010, 2009Microseismic monitoring was used to image hydraulic fracturing during a gas well stimulation. Some time after the end of the injection, there was an increase in the seismic deformation rate. Investigation of the frequency-magnitude characteristics during the pumping phase were consistent with other hydraulic fracture results, although the activity ...

Fault-tolerant model predictive control with active fault isolation
2013 Conference on Control and Fault-Tolerant Systems (SysTol), 2013A robust control method is presented for linear systems subject to input and state constraints, bounded disturbances and measurement noise, and discrete faults in sensors, actuators, and system dynamics. The approach uses set-based fault detection and isolation techniques to coordinate switching between controllers designed for each fault scenario.

Incipient faults are difficult to be detected due to the intrinsic fault tolerance of traditional controller, but it should be eliminated as soon as possible before it deteriorates with time into something more serious. As a consequence of an intrinsic inability to assess whether a fault occurs based on output residual, the existing detection methods ...

Abstract Geologically young displacements have been observed along 24 faults in an area of Alaska of approximately 624,000 km 2 . Active faults of southern Alaska include the Patton Bay and Hanning Bay reverse-slip faults, both reactivated in 1964. The Fairweather strike-slip fault experienced surface faulting in 1958 and possibly in 1899.

The flexibility and power achieved by using active networks come with their own risks - any fault in the active code or the security infrastructure now represents a fault in the network as a whole. Secure containment of active code is necessary in order to ameliorate this risk.

Abstract The power of a fault rupture beneath a dam was demonstrated when there was about 8 m of vertical movement beneath gate 17 of the Shih-Kang weir in Taiwan on 21 September 1999. The downstream damage was, in this case, minimal, but the incident has made designers very wary of attempting to build dams across potentially active ...

Fault severity in models of fault-correction activity
IEEE Transactions on Reliability, 1995This study applies canonical correlation analysis to investigate the relationships between source-code (SC) complexity and fault-correction (FC) activity. Product and process measures collected during the development of a commercial real-time product provide the data for this analysis. Sets of variables represent SC complexity and FC activity.

Active incipient fault detection with two simultaneous faults
IFAC Proceedings Volumes, 2009Abstract The problem of detecting small parameter variations in linear uncertain systems due to incipient faults, by injecting an input signal to enhance detection is considered. Unlike previous work where it is usually assumed that there is only one fault, in this paper we allow for two faults which is a natural assumption in the incipient case.
