Browsing Earth Resources Laboratory by Title
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1984)Development of borehole geophysics has recently focused on reservoir characterization. Within this effort, extensive full waveform acoustic surveys have demonstrated a correlation between the occurance of open fractures ...
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1988)The Lagrangian for guided waves in a completely general borehole model is presented. Rayleigh's principle is used to derive the first order perturbations in wavenumber and frequency due to slight perturbations in the ...
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2000)We apply an approach based on smooth neural networks to a 3D seismic survey in the Shedgum area of the Ghawar Field to estimate the reservoir porosity distribution of the Arab-D Member. We conducted numerous systematic ...
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1984)Finite difference synthetic acoustic logs are suitable for studying wave propagation in vertically varying boreholes and in boreholes with continuously varying properties. Snapshots for the traditional smooth bore in a ...
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1989)For guided wave propagation in boreholes, perturbation theory is used to calculate (1) the partial derivative of the wavenumber or frequency with respect to an elastic modulus or density, (2) group velocity, and (3) the ...
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2007)Tomographic imaging problems are typically ill-posed and often require the use of regularization techniques to guarantee a stable solution. Minimization of a weighted norm of model length is one commonly used secondary ...

-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1983)Full waveform acoustic well logging has become instrumental to hydrocarbon exploration because of its ability to determine in situ velocity information for P and S waves as well as the attenuation (or absorption) of seismic ...
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010-01-01)We investigate the applicability of an array-conditioned deconvolution technique, developed for analyzing borehole seismic exploration data, to teleseismic receiver functions and data preprocessing steps for scattered ...
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1985)A numerical investigation of asymmetric modes of elastic wave propagation in a fluid-filled borehole is treated in this paper. The dispersion curves of guided waves (called flexural waves) and synthetic microseismograms ...
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)Most acoustic logging while drilling (LWD) tools generate a single pure borehole mode (e.g., dipole or quadrupole) to estimate the formation shear velocity. We propose an approach where multipole modes are generated ...
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2009)Most acoustic LWD tools generate a single pure borehole mode (e.g., dipole or quadrupole) to estimate the formation shear velocity. We propose an approach where many borehole modes are generated and all the modes are ...
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1999)Using the amplitude versus offset (AVO) and the frequency versus offset (FVO) information, the diagnostic ability of P-wave seismic data in fracture detection is investigated. The offset-dependent attributes (AVO and FVO) ...
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1997)Research activity in the Borehole Acoustics and Logging/Reservoir Delineation Consortia continue to focus on the development of geophysical methods to detect and characterize geological conditions which control fluid ...
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1992)An exact formulation for borehole coupling, which is valid for all frequencies and all azimuthally symmetric and nonsymrnetric components, is given in this paper. The borehole effects on downhole measurements are studied ...
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1998)Measuring the electrical field induced by a borehole Stoneley wave is a new method for characterizing a rock formation around a borehole. Our field measurements demonstrate that the Stoneley-wave-induced electrical field ...
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1997)In this paper we perform the inversion of borehole resistivity data using the software package developed by Western Atlas Logging Services, Houston, TX. Direct current resistivity methods, namely lateral sounding and ...
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1994)An algorithm based on the boundary element method is established for modeling seismic source radiation from open or cased boreholes in layered transversely isotropic (TI) media. The axis of symmetry of TI layers is assumed ...
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1991)This study investigates the propagation of borehole Stoneley waves across heterogeneous and permeable structures. By modeling the structure as a zone intersecting the borehole, a simple one-dimensional theory is formulated ...
-
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1992)The attenuation of borehole Stoneley waves across a permeable structure (e.g., fractures or fracture zone) is correlated with the permeability of the structure. Using a simplified Biot theory, the structure can be modelled ...
