| Number | Title | Issue Date |
| 7433265 | Converted wave energy removal from seismic data Coherent wave noise energy is removed from seismic data by modeling both the P-wave primary energy and the coherent wave noise energy. The P-wave primary energy is modeled first and then subtracted from the input data. The data with the P-wave primary energy removed... | 10/07/2008 |
| 7039525 | Method for seismic migration using explicit depth extrapolation operators with dynamically variable operator length Explicit depth extrapolation operators are constructed with variable operator lengths depending on maximum dip angle, accuracy condition, and wavenumber. Operator tables are then constructed using the explicit depth extrapolation operators. In a further embodiment, ... | 05/02/2006 |
| 5995446 | Method of conducting drilling operations using vertical seismic profiles A method is described for providing improved seismic data to a driller to indicate position and spatial extent of a drilling target which may be up to several hundreds of feet ahead of a drill bit. In one embodiment, the method includes the steps of: surv... | 11/30/1999 |
| 5583826 | Method of processing signals for geophysical prospecting, the method making use of an improved wave field extrapolation operator The present invention relates to a method of extrapolating a set of traces recorded by means of an array of sensors, in the context of a geophysical prospecting process, the method comprising the steps consisting in: i) approximating a minus Laplacian L | 12/10/1996 |
| 5576977 | Filter for eliminating the effects of fluorescent lights on microwave transceivers A filter for eliminating the effects of fluorescent lights on microwave transceivers uses a digital comb filter to eliminate signals at the AC power line frequency and its harmonics. A preferred embodiment has an A/D converter or sampler for sampling and ... | 11/19/1996 |
| 5067112 | Method for removing coherent noise from seismic data through f-x filtering In seismic exploration, seismic reflections from subsurface formations are recorded in the form of a time-distance array of seismic traces. This array is transformed into a frequency-distance domain. Frequencies at which coherent noise resides within the ... | 11/19/1991 |
| 4875166 | Bandwidth enhancing seismic acquisition system and method A low-cut filter is provided which has a frequency response with its low frequency end attenuation limited. The low-cut filter has the effect of increasing effective channel bandwidth while simultaneously allowing low frequency signals from deep within th... | 10/17/1989 |
| 4853902 | Predictive noise filtering of multi-component seismic data An improvement in a method of treating seismic data in which predictive noise, as measured along one of the axes is discriminated and subtracted from the total signal along another of the axes recorded by geophone recording the reflection from subterranea... | 08/01/1989 |
| 4757480 | Method and apparatus for filtering seismic data A method and apparatus for filtering seismic data are provided. More particularly, the method and apparatus of the present invention attenuate surface wave generated noise in seismic-trace signals. Seismic data comprising multicomponent seismic-trace sign... | 07/12/1988 |
| 4730281 | Data processing filtering method and apparatus A bucket brigade filter is disclosed having a feedback loop resulting in a tight comb structure filter response whereby a periodic noise and all its harmonics may be removed from a signal. Scalers featuring selectively variable scaler parameters permit pr... | 03/08/1988 |
| 4312050 | Multidimensional amplitude scaling of seismic data An apparatus and method for improving seismic resolution involving the application of scaling factors to seismic data which compensate for amplitude decay as a function of time, frequency and source-to-receiver distance (position). Each seismic trace asso... | 01/19/1982 |
