地震剖面上的反射幅度异常或“亮点”作为气态碳氢化合物指示的内在可能性引起了广泛的兴趣。为了帮助评估这些可能性，实验室对孔隙率约为30%的压实渥太华沙子进行了测量。这些测量是在五种不同的含水饱和度(0%和100%，以及大约9%、45%和85%)和净围压为10000磅/平方英寸的情况下进行的。气体是空气。使用峰值频率约为700 kHz的声脉冲进行测量。
The possibilities inherent in reflection amplitude anomalies or “bright spots” on seismic cross‐sections as indications of gaseous hydrocarbons have stimulated widespread interest. To help evaluate these possibilities, laboratory measurements were made on specimens of compacted Ottawa sand of approximately 30 percent porosity. The measurements were made at five different water saturations (0 percent and 100 percent, and approximately 9 percent, 45 percent, and 85 percent) and net confining pressures to 10,000 psi. The gas was air. Measurements were made with acoustic pulses with a peak frequency of about 700 khz.
