摘要： Methods, systems, and articles of manufacture consistent with the present invention provide for determining the orientation of natural fractures in the Earth resulting from hydraulic fracturing treatment. Data attribute information from a far-field point-source signal profile for a microseismic event is extracted in the time domain. An estimate of the orientation of the natural fracture is calculated in the time domain based on the extracted data attribute information.

摘要： In oil and gas production, a process known as hydraulic fracturing is often used. Hydraulic fracturing involves pumping a fluid under pressure down a well bore into a fluid reservoir. When the pressurized fluid enters the reservoir, it produces localized failures of rock within the earth known as fractures. These fractures generate elastic waves known as microseisms that travel outward from the source of the fractures in a spherical wavefront. These microseisms can be measured with sensors located near the well bore, and their source determined. The microseismic wavefront is composed of compressional and shear waves. The amplitudes of the compressional and shear waves can be detected and measured and the ratio of the shear wave amplitude to the compressional wave amplitude which is known as the S/P ratio, can be determined. The orientation of the natural fractures in the earth are determined by comparing the S/P ratio of the waves generated by hydraulic fracturing with predicted S/P ratios for theoretical failure mechanisms and orientations. The predicted S/P ratios are calculated for theoretical failure mechanisms and orientations on the basis of the measured wave source. Forward modeling techniques are used to match the actual and predicted S/P ratios to determine the failure mechanism and the orientation of the natural fracture which generated the microseisms during the hydraulic fracturing.
摘要翻译：在石油和天然气生产中，经常使用称为水力压裂的工艺。水力压裂涉及将压力下的流体沿着井眼泵入流体储存器。当加压流体进入储层时，它产生地球内部被称为裂缝的岩石局部失效。这些裂缝产生称为微震的弹性波，其从球形波前的裂缝源向外移动。这些微震可以用位于井眼附近的传感器来测量，并确定它们的来源。微震波前由压缩波和剪切波组成。可以检测和测量压缩和剪切波的幅度，并且可以确定剪切波幅度与称为S / P比的压缩波幅度的比值。通过将水力压裂产生的波的S / P比与预测的理论失效机理和取向的S / P比进行比较，确定了地球天然裂缝的取向。基于测量的波源计算理论故障机理和取向的预测S / P比。使用前向建模技术来匹配实际和预测的S / P比，以确定在水力压裂过程中产生微震的天然裂缝的失效机理和取向。

摘要： An apparatus and method for measuring deformation of a rock mass around the vicinity of a fracture, commonly induced by hydraulic fracturing is provided. To this end, a well is drilled offset from the proposed fracture region, if no existing well is present. Once the well is formed to a depth approximately equal or exceeding the depth of the proposed fracture, a plurality of inclinometers, for example tiltmeters, are inserted downhole in the well. The inclinometers are located both above and below the approximate depth of the proposed fracture. The plurality of inclinometers may be arranged on a wireline that may be retrieved from the downhole portion of the well and used again or, alternatively, the inclinometers may be cemented in place. In either event, the inclinometers are used to measure the deformation of the rock around the induced fracture.
