description A latching assembly for wellbore logging tools includes a bottom hole assembly to be disposed on a distal end of a drill string. The bottom hole assembly includes a landing sub (310) having a bore with a latching mechanism that includes latch jaws (321) and bias springs (323). The latch jaws can receive a landing shoulder (215). The biasing spring has a closing arm (352) and an opening arm (354) to respectively close and open the latch jaws. The bottom hole assembly includes a tool string (200) that includes the landing shoulder for engaging with the latch jaw of the landing sub, the biasing spring, and a logging assembly that includes at least one logging tool for obtaining and storing data about at least one geologic formation penetrated by the wellbore.
