Abstract: An interrogation system includes a light signal switch and a reflection signal switch. The light signal switch may be communicatively coupled to an optical light source. The light signal switch may route a light signal generated by the light source downhole in a wellbore through a single-mode optical fiber cable or a multi-mode optical fiber cable. The reflection signal switch may be communicatively coupled to the single-mode optical fiber cable and the multi-mode optical fiber cable. The reflection signal switch may route a reflection of the light signal from the signal-mode optical fiber cable or the multi-mode optical fiber cable to an optical detector.

Abstract: An illustrative monitoring system for a hydraulic fracturing operation includes: a data acquisition module collecting microseismic signals from a subterranean formation undergoing a hydraulic fracturing operation; a processing module implementing a monitoring method; and a visualization module that displays an estimate or prediction of fracture extent. The monitoring method implemented by the processing module includes: deriving microseismic event locations and times from the microseismic signals; fitting at least one fracture plane to the microseismic event locations; projecting each microseismic event location onto at least one fracture plane; determining a time-dependent distribution of the projected microseismic event locations; calculating one or more envelope parameters from the time-dependent distribution; and generating an estimate or prediction of fracture extent using the one or more envelope parameters. The envelope parameters may include an exponent of a time -power law, and said generating may include re-fitting the fracture plane if the exponent isn't approximately one-half.

Abstract: Microseismic behavior in a multi-stage stimulation process in respect of a geological formation is predicted by identifying a primary factor contributing to a type and pattern of observed microseismicity associated with a stimulation stage. The identification involves postulating a candidate factor contributing to the type and pattern of the observed microseismicity associated with the stimulation stage. The identification also includes determining whether the candidate factor contributes to the type and pattern of the observed microseismicity using a physical analysis technique, thereby testing the candidacy of the candidate factor.

Abstract: Uncertainty in microseismic monitoring sensor data can be reduced. A computing device can receive information about at least one sensor that is monitoring a subterranean formation, including a location, after a fracturing fluid is introduced into the formation. The computing device can also receive information about a microseismic event and determine a seismic ray bath between a location of the event and the at least one sensor, and an uncertainty value of the location based on information about the formation and the information about the event. The computing device can determine a total uncertainty value associated with the locations of a plurality of microseismic events, including the microseismic event. The computing device can determine a solution to an objective function based on the total uncertainty value and a number of sensors. The computing device can determine a new location of the at least one sensor based on the solution.

Abstract: Some aspects of what is described here relate to seismic profiling techniques. A seismic excitation is generated in a first directional section of a first wellbore in a subterranean region. Seismic responses associated with the seismic excitation are detected in directional sections of a plurality of other wellbores in the subterranean region. A fracture treatment of the subterranean region is analyzed based on the seismic responses. In some instances, a multi-dimensional seismic velocity model of the subterranean region is generated based on the seismic responses.

Abstract: 本发明公开了一种数字信号提频处理方法，其包括以下步骤：S101、输入一定时间里采集到的实信号道；S102、对所述实信号道进行希尔伯特变换以获取所述实信号道的瞬时振幅道；S103、基于所述瞬时振幅道对实信号道进行提频和极性变换处理，以获取提频信号道。由于消除了事件信号的极性，并且提高了频率，有效的弱事件信号与无效的干扰信号更容易区分，因此不需要大量强事件便能识別出微弱信号源，这在页岩气压裂微地震监测领域中彰显了环境保护和降低成本的优点。此外，本发明的零极性变换和提频处理的步骤简单、通用性强，一旦常数k1和k2给定，可以实现任何信号的信频和零极性处理。

Abstract: The methods described are for determining distribution, orientation and dimensions of networks of hydraulically-induced fractures within a subterranean formation containing fluids. Detectable signals are generated by particles introduced into the fractures. In an exemplary method proppant-like particles are positioned in the formation during fracturing and allowed to generate a signal during or after fracturing activity. The detectable signals generated by the proppant-like particles are used to map fracture space.
