METHODS FOR DETERMINING WELL LOG ATTRIBUTES FOR FORMATION CHARACTERIZATION |
| 摘要 |
A method for characterizing subsurface formations penetrated by a wellbore includes accepting as input to a computer measurements of a physical parameter of the formations made over a selected axial interval of the wellbore. At least one attribute of the measurements is determined from a change in the measurements over the selected axial interval. At least one characteristic of the formations in the selected axial interval using the at least one attribute. |

1. A method for characterizing subsurface formations penetrated by a wellbore, comprising:
accepting as input to a computer measurements of a physical parameter of the formations made over a selected axial interval of the wellbore; in the computer calculating at least one attribute of the measurements (measured values) from a change in the measurements over the selected axial (depth) interval, wherein the attribute is directly related to a shape of a curve defined by the change in measurements over the selected axial interval; and in the computer determining a characteristic of the formations in the selected axial interval using the at least one attribute, wherein the characteristic is related to the defined shape. |
