REAL TIME SURVEYING WHILE DRILLING

A method for drilling a subterranean wellbore includes rotating a drill string in the subterranean wellbore. The drill string includes a drill collar, a drill bit, and survey sensors (e.g., a triaxial accelerometer set and a triaxial magnetometer set) deployed therein. The triaxial accelerometer set...

Zusammenfassung:	A method for drilling a subterranean wellbore includes rotating a drill string in the subterranean wellbore. The drill string includes a drill collar, a drill bit, and survey sensors (e.g., a triaxial accelerometer set and a triaxial magnetometer set) deployed therein. The triaxial accelerometer set and the triaxial magnetometer set make corresponding accelerometer and magnetometer measurements while drilling (rotating). These measurements are synchronized to obtain synchronized accelerometer and magnetometer measurements and then further processed to compute at least an inclination and an azimuth of the subterranean wellbore while drilling. The method may further optionally include changing a direction of drilling the subterranean wellbore in response to the computed inclination and azimuth.
