| 1321271 Acoustic inspection devices SCHLUMBERGER INLAND SERVICES Inc 9 July 1970 [9 July 1969] 33438/70 Heading H4D The integrity of the cement packing between a well casing and surrounding earth formations is investigated by transmitting acoustic energy so that a component propagates from the well bore into the casing and earth formations, receiving a reflected portion of the energy and separating it into acoustic frequency spectrum bands, and generating signals respectively representing the acoustic reflection coefficient in at least three selected spectrum bands. It is shown mathematically that, for a given well casing and borehole size, three frequency bands can be selected such that the reflection coefficients for two of the bands would be relatively low if there were good cementing, while at most one reflection coefficient would be relatively low for poor cementing. In the embodiment of Figs. 6 and 7 a conventional logging tool (Fig. 6) has several acoustic pulse transmitters and receivers T, R which can be selected in pairs by means of programmer 36, control signal generator 34, selector control 54 and selector unit 56. The tool is constructed substantially to prevent direct passage of acoustic energy between the transmitters and receivers. Receiver output signals are passed via channel 60 (which is blanked during the acoustic pulse transmission) and detector 42 (which is gated on when acoustic signals are expected to reach a receiver via the earth formations, cement and well easing) to acoustic travel time computer 44 and to cement evaluation computer 70, the computer outputs being logged at 52 and 71 as a function of tool depth in the well. In the cement evaluation computer (Fig. 7) the time-gated receiver signals are split into the three selected frequency bands (e.g. 10-15 kHz, 15-25 kHz and 25-40 kHz) by filters 81, 82, 83 whose amplified outputs are integrated (with respect to frequency) respectively at 87, 88, 89 to provide three signals of amplitude representing the reflection coefficients in those bands. Selectable gain amplifiers 84, 85, 86 compensate for the frequency response of the logging tool transducers. Circuit 90 (detailed in Fig. 9, not shown) selects the lowest two of the three reflection coefficient signals and averages them, this average being logged. The reflection coefficient signals are recorded individually at 91. The cement evaluation computer may be operated off-line, by recording on magnetic tape the logging tool acoustic waveforms or the outputs of integrators 87, 88, 89, and may be a digital filtering and processing system instead of the system shown (details given). The cement integrity log may be displayed on an oscilloscope or recorded by a digital printer. | ||||||

| A cement bond log from recorded ultrasonic waveforms, a method for evaluating bonding of cement in a wellbore between a casing and a wellbore wall, and a method for creating a cement bond log from recorded ultrasonic waveforms are disclosed, in which series of points corresponding to maxima and minima of the waveforms are identified. Absolute value amplitudes of the series of points are thereafter identified and a correlation thereof is analyzed to divide each series of points into four or more zones, corresponding to casing arrival data, inner and outer annular data, wellbore wall arrival data, respectively. Mean values of the absolute value amplitudes of the waveforms for points of each series falling within each of the four zones are calculated, which relate to cement bonding at the depths of the recorded ultrasonic waveforms. | ||||||

| 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. | ||||||

The method may then determine properties associated with the wellbore fluid over a period of time based on the data; determine temperature values associated with the wellbore fluid based on the data and the properties associated with the wellbore fluid; determine an expected shape of the annulus space based on the data, the properties associated with the wellbore fluid, and the temperature values; and determine bottom-hole fluid properties associated with the wellbore fluid based on the properties of the wellbore fluid and the temperature values. The method may then generate a wellbore fluid placement map based on the bottom-hole fluid properties, the shape of the annulus space, and the temperature values, such that the wellbore fluid placement map includes expected concentration levels of the wellbore fluid.

| Systems, methods, and computer-readable storage devices for determining a location of an acoustic source outside of a borehole. The method relates to indicating a radial distance to the borehole, an offset along the borehole, and an azimuthal position around the borehole, of the acoustic source. The method includes receiving acoustic signals from respective acoustic sensors spaced along a tool lowered within the borehole. Using the acoustic signals and a borehole model, stacked energies are calculated for different radial distances from the borehole. At least one of the stacked energies is translated to an indication of a radial distance of the acoustic source from the borehole. The stacked energy for a radial distance is computed by offsetting the acoustic data signals in time in accordance the borehole model, summing the offset acoustic data signals to produce a stacked signal, and evaluating energy of the stacked signal over a time window. | ||||||
