Development of DARS II for the measurement of pressure dependent quality factor and compressibility of small rock samples
Abstract/Contents
- Abstract
- Sample quality factor remains largely ignored due to difficulties in quantifying and repeating results. This thesis describes a Differential Acoustic Resonance Spectroscopy system, (DARS II), an acoustic method developed to study sample quality factor as a function of confining pressure at a kilohertz frequency scale. The work is subdivided into five parts: A review of the proof-of-concept system, DARS I; DARS II design and construction; DARS II empty-system characterization; Non-porous sample compressibility and attenuation estimates as a function of pressure; and Shale sample quality factor and attenuation estimates as a function of pressure. The primary contribution of this study is the design and construction of a system which estimates the resonant frequency, amplitude, and linewidth of porous and non-porous media with variable confining pressure at about 1000 Hz. The DARS II resonant frequency and linewidth measurements are used to estimate sample compressibility and quality factor with change in pressure measured at low frequencies. The method may be applied to regular or irregular shaped non-porous and porous samples
