摘要:
Seismic data is collected by using an electrical submersible pump assembly in a well that is producing well fluid. By sweeping the rotational speed of the pump assembly through a selected range at selected intervals, seismic waves of varying frequency are emitted. These seismic waves are then picked up with a seismic sensor located at the surface or located in another well. If the seismic sensors are located in another well, the signal from the sensor may be transmitted to the surface by superimposing the data onto the power cable leading to the pump located in that other well. The seismic survey may be repeated at regular intervals, and the results will reveal the changes that have taken place over time in the reservoir.

1st order free-surface multiples recorded in VSP data or reverse VSP data are processed using a 3-C 3-D vector migration method to produce an image of the subsurface. This image produces a larger coverage than that obtained in 3-C 3-D processing of reflection data acquired in the VSP.

摘要:
A walkaway VSP survey is carried out with receivers located in a borehole under a salt overhang. Redatuming of the multicomponent data to virtual sources in the borehole followed by vector Kirchhoff migration using a simple velocity model provides an accurate image of the salt face.

摘要:
A walkaway VSP survey is carried out with receivers located in a borehole near the base salt. Reflection tomographic inversion of data from the walkaway VSP is used to derive a velocity model for the subsurface and may be used for imaging of sub-salt reflections.

A seismic and/or acoustic while drilling configuration includes a high speed telemetry arrangement; at least one seismic and/or acoustic energy sensor in communication with the high speed telemetry arrangement; at least one seismic and/or acoustic energy source capable of producing at least one seismic and/or acoustic energy signal receivable by the at least one seismic and/or acoustic energy sensor and methods.
摘要:
A method of making a thermal barrier construction element or shape, wherein a single metal construction element of a predetermined design or shape having a suitable opening therein for receiving an insulating member, is extruded in a normal manner, the insulating member is inserted in the receiving opening of the metal extrusion, the metal extrusion is crimped or stitched whereby the insulating member is mechanically locked in position in the metal extrusion, and a portion of the metal extrusion is subsequently removed therefrom to provide the thermal barrier construction element.
