Simultaneous Inversion of cross-dipole acoustic waveforms in anisotropic media for azimuthal angle and dispersion of fast and slow shear waves 

Briggs, Victoria; Rao, Rama V. N.; Burns, Daniel R. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2003)
A method to jointly invert for azimuthal angle and dispersion relations from cross-dipole data is presented. Dispersion curves from the joint inversion are compared to both Prony’s method and a simple back propagation ...

Measured radiation patterns of the scale model dipole tool 

Lu, Rongrong; Rao, Rama V. N.; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 2003)
The sound field of finite dipole acoustic transducers in a steel tool was investigated and their horizontal by measuring their vertical radiation patterns in water at two different frequencies. Measurements were also made ...

Fracture Density Estimation Using Spectral Analysis of Reservoir Reflections: A Numerical Modeling Approach 

Pearce, Fred; Burns, Daniel R.; Rao, Rama V. N.; Willis, Mark E.; Byun, Joongmoo (Massachusetts Institute of Technology. Earth Resources Laboratory, 2003)
We use a 3-D finite difference numerical model to generate synthetic seismograms from a simple fractured reservoir containing evenly spaced, discrete, vertical fractures. The fractures are represented using a single column ...

An integrated well data analysis for in-situ stress estimation 

Grandi, Samantha K.; Rao, Rama V. N.; Huang, Xiaojun; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 2003)
In this paper we obtain in-situ stress information based on two methods. The first one consists in matching borehole deformations to the modelling of linear poroelasticity equations around a hole in a plate that is subjected ...

Characterization of Scattered Waves from Fractures by Estimating the Transfer Function Between Reflected Events Above and Below Each Interval 

Willis, Mark E.; Burns, Daniel R.; Rao, Rama V. N.; Minsley, Burke J. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2003)
It is important to be able to detect and characterize naturally occurring fractures in reservoirs using surface seismic reflection data. 3D finite difference elastic modeling is used to create simulated surface seismic ...
