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 |

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 |

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 |

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. |
