TLC System

A method of conveyance utilizing the

drill pipe to push logging services through

well bores which are horizontal or otherwise

difficult to log using conventional methods.

LWD Acquisition Workflow - Differences

between Wireline and LWD • Wireline

– Data are directly associated to depth indexes

• LWD

– Tools do not know the depth / only surface

systems know the bit depth

– Tools record data in time

– 2 types of acquisition: Real-Time and Recorded

Mode
