摘要： Methods, systems, and devices for determining a parameter of interest of downhole fluid using an acoustic assembly comprising a single solid acoustic transmission medium having a face immersed in the downhole fluid. Methods include using characteristics of a plurality of acoustic pulse reflections from a solid-liquid interface at the face of the solid acoustic transmission medium to estimate the parameter of interest in near real-time. The characteristics may comprise a corresponding reflection amplitude and the corresponding unique angle of reflection for each acoustic pulse reflection. Methods may include generating a two dimensional data set from measured characteristics, generating a curve by performing data fitting on the two dimensional data set, and using the reciprocal slope of the curve to estimate the parameter of interest. Methods may include estimating time-dependent values for the parameter of interest substantially continuously while the acoustic assembly is on a single logging run in the borehole.

摘要： Sonic data, ultrasonic data, and density data of the annulus are obtained using a sonic tool, an ultrasonic tool, and a density tool, respectively, included in a tool string. A first deconvolution operation is performed to obtain an amplitude, a frequency, and a phase of the modified sonic wave. A first inverse modeling operation results in a first density value of the annular media. A second deconvolution operation is performed to obtain an amplitude, a frequency, and a phase of the modified ultrasonic wave. A second inverse modeling operation results in a second density value of the annular media. A third deconvolution operation is performed to obtain far counts, near counts, and an energy spectrum of gamma rays. A third inverse modeling operation results in a third density value of the annular media.

摘要： A method that includes obtaining log data of a downhole formation, and characterizing the downhole formation by determining stiffness coefficients including C33, C44, C66, C11, C12, and C13. C13 is a function of C33, C44, C66, and at least one of a kerogen volume and a clay volume derived from the log data. In another method or system, C13 is derived based at least in part on C11 calculated as C11=k1[C33+2(C66−C44)]+k2 or C33 calculated as C33=((C11−k2)/k1)−2(C66−C44), where k1 and k2 are predetermined constants. In another method or system, C13 is derived in part from at least one of a kerogen volume derived from the log data, a clay volume derived from the log data, C11 calculated as C11=k1[C33+2(C66−C44)]+k2, or C33 calculated as C33=((C11−k2)/k1)−2(C66−C44), where k1 and k2 are predetermined constants.

摘要： A method for processing microseismic data, comprises: receiving the microseismic data acquired by one or more multicomponent sensors; convolving the microseismic data with an operator that is applied to all of the components of the microseismic data; and applying a multicomponent filter operator to the convolved microseismic data. The microseismic data may result from human activity or be entirely natural. The filtering preserves the polarity of the received data whilst improving the signal-to-noise ratio of the filtered data.
