Abstract
A method for conveying logging tools (LT) and obtaining well log data from a wellbore is disclosed. The method includes running a drill string (DS) including a landing sub (LS) disposed near the lower end into a wellbore. A logging tool string (LTS) is inserted into the upper end of the DS bore. A fluid is pumped into the upper end of the DS bore to assist movement of the LTS. As the fluid is pumped behind the LTS, the cable at the surface is spooled out and the fluid pressure is monitored. The landing assembly of the LTS is landed in the LS. A diagnostic test is activated and run to determine proper functioning of the LT. A release mechanism releases the running tool portion of the LTS. The cable is spooled in. The drill pipe string is pulled upward in the wellbore as the LT are recording data.
