Abstract
A system for determining depth within a borehole. The system includes a downhole device having at least one inertial sensor, at least one processor, and a memory in communication with the at least one processor. The memory can include instructions thereon that, when executed, cause the processor to: receive data from the at least one inertial sensor and store the data from the at least one inertial sensor in the memory with respective correlated time values. The system can further include a drill rig having at least one depth measurement device. The at least one depth measurement device can include a drill string position sensor that is configured to produce a measurement indicative of a length of a portion of a drill string removed from a borehole or a wireline sensor that is configured to determine a length of deployed wireline cable.
