Patent Number Title Of Patent Date Issued
4745562 Signal processing disparity resolution May 17, 1988
A process for signal matching. The process is general and can be applied to matching signals of arbitrary dimension. To implement the process, a suitable discretized description of the two signals to be matched is defined. Such descriptions can be the local signal extrema or any other
4327412 Well logging data processing technique April 27, 1982
In accordance with an illustrative embodiment of the invention, a technique is set forth for determining a displacement between two or more well logs separately derived from investigating devices passed through a borehole. More particularly, displacements are determined for a number of l
4314339 Method of generating subsurface characteristics models February 2, 1982
A method of computer generating a subsurface characteristic model which is substantially consistent with readings taken in a well with the well logging device. A set of actual measurement values which represent readings taken over a given depth interval of the well is derived. An ini
4314338 Method of generating subsurface characteristic models February 2, 1982
A method of computer generating a subsurface characteristic model which is substantially consistent with readings taken in a well with a well logging device. A set of actual measurement values which represent readings taken over a given depth interval of a well is derived. An initial tri
4313164 Method of generating subsurface characteristic models January 26, 1982

4312040 Well log depth aligning January 19, 1982
In accordance with an illustrative embodiment of the invention, a technique is set forth for determining the depth match between two or more well logs derived from separate passes through a borehole. More particularly, first assumption depth displacement values are determined for a numbe
3973188 Method and apparatus for the determination of the thickness of a mudcake layer on a borehole wal August 3, 1976
An electrical well logging apparatus of the spherical focusing type is suspended in a borehole drilled into an earth formation and is utilized to provide information regarding the thickness of the mudcake formed on the borehole wall.
