Abstract

The centroid frequency shift method is proposed to estimate seismic attenuation from full waveform acoustic logs. This approach along with the amplitude ratio method is applied to investigate the attenuation properties of the P head wave in fluid-filled boreholes. The generalized reflection and transmission coefficients method is used to perform forward modeling. The authors suggest an empirical formula to describe the frequency-dependent geometrical spreading of the P-wave in a borehole. They simulate a more realistic borehole by including a mudcake and an invaded zone which are modeled by a large number of radially symmetric thin layers. The numerical tests show that this invaded zone exhibits very strong influence on the attenuation measurement.

Seismogram synthesis for radially layered media using the generalized reflection/transmission coefficients method: Theory and applications to acoustic logging

Journal Article Chen, X; Quan, Y; Harris, J - Geophysics

A new method based on generalized reflection and transmission coefficients is proposed to calculate the synthetic seismograms in radially multilayered media. This method can be used to efficiently simulate full waveform acoustic logs and crosswell seismic profiles in situations where one needs to consider borehole effects. The new formulation is tested by comparing the authors` numerical results with previous available work and shows excellent agreement. Because of the use of the normalized Hankel functions and the normalization factors, this new algorithm for computing seismograms is stable numerically even for high-frequency problems. To show the applicability of this new approach tomore »« less

Estimations of formation velocity, permeability, and shear-wave anisotropy using acoustic logs

Journal Article Cheng, N; Cheng, C - Geophysics

Field data sets collected by an array monopole acoustic logging tool and a shear wave logging tool are processed and interpreted. The P- and S-wave velocities of the formation are determined by threshold detection with cross-correlation correction from the full waveform and the shear-wave log, respectively. The array monopole acoustic logging data are also processed using the extended Prony`s method to estimate the borehole Stoneley wave phase velocity and attenuation as a function of frequency. The well formation between depths of 2,950 and 3,150 ft (899 and 960 m) can be described as an isotropic elastic medium. The inverted V{submore »« less

Determination of in situ attenuation from full waveform acoustic logs

Journal Article Cheng, C; Toksoez, M; Willis, M - J. Geophys. Res.; (United States)

Method for the determination of in situ P and S wave attenuation from full waveform acoustic logs are developed. For P waves, the peak amplitude ratios of the refracted P waves from two different receivers can be used with geometrical spreading taken into account. For S waves, owing to the contamination by the guided waves, its attenuation cannot be determined directly. Instead, S wave attenuation is determined from the attenuation of the guided waves using the partition coefficients (normalized partial derivatives of the phase velocity with respect to the body wave velocities). Analytical forms of these partition coefficients are presentedmore »« less

Acoustic well logging method and apparatus

Patent Liu, O

A method is described for determining the permeability of a subsurface geological formation traversed by a borehole, comprising the steps of: (a) passing a logging tool through the borehole, the logging tool including a rare earth acoustic transducer; (b) generating low frequency acoustic energy at a point in the borehole using the rare earth acoustic transducer; (c) receiving acoustic signals at a plurality of receiver stations spaced one from the other and from the rare earth acoustic transducer; (d)producing full waveforms of the received signals including shear waves and Stoneley waves for the point in the borehole; (e) measuring valuesmore »« less
A METHODOLOGY TO INTEGRATE MAGNETIC RESONANCE AND ACOUSTIC MEASUREMENTS FOR RESERVOIR CHARACTERIZATION

Technical Report Parra, Jorge; Hackert, Chris; Wilson, Lorna

The work reported herein represents the third year of development efforts on a methodology to interpret magnetic resonance and acoustic measurements for reservoir characterization. In this last phase of the project we characterize a vuggy carbonate aquifer in the Hillsboro Basin, Palm Beach County, South Florida, using two data sets--the first generated by velocity tomography and the second generated by reflection tomography. First, we integrate optical macroscopic (OM), scanning electron microscope (SEM) and x-ray computed tomography (CT) images, as well as petrography, as a first step in characterizing the aquifer pore system. This pore scale integration provides information with whichmore »« less
