Publication number: 20100096187Abstract: Embodiments of the present invention generally relate to methods and systems for logging through a drillstring. In one embodiment, a method of logging an exposed formation includes drilling a wellbore by rotating a cutting tool disposed on an end of a drillstring and injecting drilling fluid through the drillstring; deploying a BHA through the drillstring, the BHA including a logging tool; forming a bore through the cutting tool; inserting the logging tool through the bore; longitudinally connecting the BHA to the drillstring; and logging the exposed formation using the logging tool while tripping the drillstring into or from the wellbore.Type: ApplicationFiled: October 20, 2009Publication date: April 22, 2010Inventors: Bruce H. Storm, JR., James G. Aivalis, Bulent Finci, Peter Wells, Akio Kita, Eric Johnson, Jonathan Macrae
