摘要： In accordance with illustrative embodiments of the present invention, techniques are disclosed for compensating acoustic well logging measurements for variations in one or more conditions of a well bore. More particularly, these measurements are compensated for variations in well bore cross-section, and well bore fluid acoustic impedance and velocity. These compensation techniques have particular significance in connection with systems of the type which scan a well bore wall by rotating a transducer means which emits directional bursts of high frequency acoustic energy and receives energy reflected off the bore wall. The electrical signals produced by this received energy are suitably processed to provide information relative to the character of the media forming the well bore wall.

摘要： A SONIC SIGNAL GENERATOR AND RECEIVER ARE PLACED IN VERTICAL SPACED RELATIONSHIP IN A WELL BORE. THE RECEIVER ESTABLISHES AN ANALOG OUTPUT SIGNAL. THIS SIGNAL IS CONVERTED TO A CORRESPONDING DIGITAL SIGNAL BY DIVIDING THE ANALOG SIGNAL INTO SUCCESSIVE INCREMENTS AT A FIRST RATE. THE RESULTING INCREMENTS ARE PASSED TO INDIVIDUAL SIGNAL STORAGE DEVICES. THE INCREMENTS ARE SUBSEQUENTLY REMOVED FROM THE STORAGE DEVICES IN SEQUENCE AT A PRESELECTED SECOND RATE WHICH IS SLOWER THAN THE FIRST RATE, AND THE REMOVED INCREMENTS ARE CONVERTED INTO CORRESPONDING DIGITIZED SIGNALS.

摘要： Implementations described and claimed herein provide systems and methods for isolation detection. In one implementation, an axial acoustic signal is obtained. The axial acoustic signal is captured using an axial sensor deployed in a structure in a subterranean surface. The axial acoustic signal is separated into a first wave region and a second wave region by applying velocity filtering. An axial symmetry of a portion of the structure is determined based on at least one of the first wave region or the second wave region.

摘要： A method and system for generating an acoustic log. The method may comprise disposing an acoustic logging tool in a wellbore, broadcasting a shaped signal with the acoustic logging tool such that the shaped signal interacts with a boundary of a casing and a material, recording a result signal from the boundary with the acoustic logging tool, and decomposing the result signal into a resonance mode. The method may further comprise applying a bandpass filter to the resonance mode to form a filtered signal, selecting a baseline signal from the filtered signal, removing the baseline signal from the filtered signal, and generating a log from the filtered signal. The system may comprise an acoustic logging tool. The acoustic logging tool may comprise at least one transmitter and at least one receiver. The system may further comprise a conveyance and an information handling system communicatively connected to the acoustic logging tool.

摘要： A pressure wave is generated within a first well extending into a subterranean formation. A pressure response associated with the pressure wave is detected from a second well extending into the formation. Information is then determined, based on the pressure response in the second well, wherein the information is associated with at least one of the formation and a fracture connected to at least one of the first well and the second well.

The method may further include generating sponge core data of the geological region of interest using a neural network model and the dielectric log data. The neural network model may be trained using various dielectric logs from various well sources. The method may further include determining, using the sponge core data, an amount of hydrocarbons in the geological region of interest.

摘要： System and method for guiding a drill using a subsurface model generated by successive full waveform inversions (FWI) on surface data and seismic-while-drilling (SWD) data. A server receives surface data from at least one surface sensor that records elastic energy radiated from surface seismic source and SWD data from at least one surface or at least one subsurface crosswell sensor (i.e., deployed in a nearby well). The server also receives top-drive measurements. A drillbit source signature estimation is performed, on the SWD data, by the server by blind deconvolution or by using drill string modeling and top-drive measurements. The server then performs FWI on the surface data by using the background subsurface velocity obtained by kinematic analysis of surface seismic data, to obtain an updated approximation of the subsurface velocity. The new approximation along with the drillbit source signature is then used when performing FWI on the SWD data.
