Abstract: Embodiments of super-virtual borehole sonic interferometry include machines, systems, and methods that can increase the signal-to-noise ratio of sonic log waveforms. Embodiments include performing a common shot gather and recording traces with a sonic tool, repositioning the tool and performing another common-shot gather; cross-correlating each trace with neighboring corresponding traces for each common shot gather, which leads to creating the virtual trace response due to a redatumed virtual source; stacking the common virtual traces with common ray paths for different common shot gathers; convolving the virtual traces with an actual trace that travels from the source through the virtual source to a receiver on the tool; and stacking the traces having common ray paths. The resulting waveforms can have a signal-to-noise ratio significantly greater than the signal-to-noise ratio of the original waveforms, due to the two stacking operations following each redatuming step.

Abstract: Methods and an alarming system for long-term carbon dioxide sequestration in a geologic reservoir are described. The geologic reservoir may be a water filled sandstone reservoir or a carbonate reservoir. A reservoir model is constructed to show the effects of varying injection pressures, the number of injection wells, the arrangement of injection wells, the boundary conditions and sizes of the reservoir on caprock uplift, fracture formation and fracture reactivation. The alarming system generates an alarm when caprock uplift that surpasses a threshold is detected. The injection pressures and the number of injection wells operating may be varied in response to the alarm.

Abstract: A formation evaluating system including a sonic sensor device attached to a drill string adjacent to a bit includes a sonic source and a first sonic receiver aligned adjacent to the sonic source, and a second sonic receiver aligned with a horizontal offset X. Three kind of two-way trip times are measured: from the sonic source to a) the first receiver after a reflection at the borehole wall, b) the first receiver after propagation in a layer below the borehole wall, an invaded zone, and a reflection at an interface below the borehole wall, and c) the second receiver after oblique propagations in the invaded zone and a reflection at the interface. After determining a sonic speed in the drilling mud and a sonic speed in a matrix of the invaded zone, a porosity and a thickness of the invaded zone are estimated based on a time average equation.

Abstract translation: 超虚拟井眼声波干涉测量的实施例包括可以增加声波测井波形的信噪比的机器，系统和方法。 实施例包括用声波工具执行共同拍摄聚集和记录迹线，重新定位工具并执行另一个共同聚光; 将每个跟踪与每个共同拍摄集合的相邻对应轨迹互相关，这导致由于重绘的虚拟源而创建虚拟跟踪响应; 用普通的射线路径堆叠共同的虚拟轨迹，用于不同的共同射击集合; 将虚拟轨迹与从源通过虚拟源传播到工具上的接收器的实际轨迹进行卷积; 并堆叠具有共同射线路径的迹线。 由于在每个重做步骤之后的两次堆叠操作，所得到的波形可以具有明显大于原始波形的信噪比的信噪比。

Abstract: Aspects of the disclosure provide a system for seismic sample data acquisition and processing. The system includes an acquisition system configured to acquire seismic sample data using compressive sensing. The acquisition system includes a plurality of receivers each configured to randomly sample a seismic signal to generate seismic sample data, and a data collection system configured to control sampling operations of the plurality of receivers, and receive and store the generated seismic sample data.
