Filed:

Nov 2, 2005

Appl. No.:

12/091426

Inventors:

Paul C. Morin - Keller TX, US
Michael Greene - Canyon TX, US

Assignee:

Bell Helicopter Textron Inc. - Fort Woth TX

International Classification:

B25B 27/14

US Classification:

29271, 29278, 29256

Abstract:

A mandrel extraction tool includes an actuator assembly and a first mandrel interface arm operably associated with the actuator assembly and adapted to engage a first mandrel. The mandrel extraction tool further includes a second mandrel interface arm operably associated with the actuator assembly and adapted to engage a second mandrel, the second mandrel interface arm being slidingly coupled with the first mandrel interface arm, such that the first mandrel interface arm moves generally linearly with respect to second interface arm when the actuator assembly is actuated. A method for extracting a mandrel includes providing a mandrel extraction tool, engaging the mandrel extraction tool with a mandrel, and applying a force to the mandrel to linearly extract the mandrel from a first portion of a structure.

Michael G. Greene - Sugar Land TX, US

Assignee:

Chevron U.S.A. Inc. - San Ramon CA

International Classification:

G06F 19/00

US Classification:

702 14

Abstract:

A computer-implemented method for processing seismic data includes the determining, from the seismic data, a first amplitude attribute map at a first image depth corresponding to a shallow attenuating body, and a second amplitude attribute map at a second image or target depth. The first and second amplitude attribute maps are then normalized, and a ratio map is determined based on a ratio of the normalized first and second amplitude attribute maps. The ratio map is scaled to yield a scale factor map, which is then applied to the seismic data to compensate for effects of shallow overburden attenuation.

International Classification:

G01V 1/48
G01V 13/00

Abstract:

Methods and systems for calibrating depth in a well to seismic data in a subsurface volume of interest are disclosed. Exemplary implementations may: obtain well data corresponding to the well in the subsurface volume of interest; convert the well data to converted well data; obtain a seismic trace and a corresponding wavelet; generate a transform model; apply the transform model to the converted well data to transform the converted well data into transformed well data; apply the corresponding wavelet to the transformed well data to generate a modified signal; generate a correspondence between the modified signal and the seismic trace; repeat one or more steps to select a given modified signal; and calibrate the well data to the seismic trace.

Inventors:

Assignee:

Chevron U.S.A. Inc. - San Ramon CA

International Classification:

G01V 1/28

Abstract:

A method is described for of creating a high-resolution velocity model of a geological medium that includes generating a long-wavelength anisotropic velocity model using tomographic inversion of seismic data gathers and combining the long-wavelength velocity model with an attenuation model. The method further includes performing prestack depth migration on the seismic data gathers using the long-wavelength velocity and attenuation model to produce seismic image gathers, applying a dip-consistent filter to the seismic image gathers, and transforming the filtered seismic image gathers to the time domain. The method further includes generating a full-band impedance model by performing impedance inversion of the time-domain filtered seismic image gathers using the long-wavelength velocity and attenuation model. The full-band impedance or velocity model is calibrated in the frequency domain in a manner independent of the spatial coordinates. The full-band impedance or velocity model is used for detecting fluid pressure anomalies in the geological medium.

International Classification:

G01V 1/36

Abstract:

A computer-implemented method for processing seismic data includes the determining, from the seismic data, a first amplitude attribute map at a first image depth corresponding to a shallow attenuating body, and a second amplitude attribute map at a second image or target depth. The first and second amplitude attribute maps are then normalized, and a ratio map is determined based on a ratio of the normalized first and second amplitude attribute maps. The ratio map is scaled to yield a scale factor map, which is then applied to the seismic data to compensate for effects of shallow overburden attenuation. The corrected seismic data may be used for subsurface characterization.
