Method for salt and cross-bed proximity detection using deep directional electromagnetic measurements while drilling |
摘要 |
A method for drilling a wellbore proximate a salt structure includes measuring formation resistivity azimuthally. A map of spatial distribution of resistivity is determined from the azimuthal resistivity measurements. A distance from the wellbore to an edge of the salt structure is determined from the three dimensional volume map.
