| Title: |
MEASUREMENT-WHILE-DRILLING ASSEMBLY USING REAL-TIME TOOLFACE ORIENTED MEASUREMENTS |
| Abstract: |
This invention provides a measurement-while-drilling (MWD) downhole assembly (90) for use in drilling boreholes which utilizes directional formation evaluation devices on a rotating assembly in conjunction with toolface orientation sensors. The data from the toolface orientation sensors are ananlyzed by a processor and toolface angle measurements are determined at defined intervals. Formation evaluation sensors operate substantially independently of the toolface orientation sensors and measurements of the formation evaluation sensors are analyzed in combination with the determined toolface angle to obtain formation parameters. |
