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.
DWCH-C (Down hole Wet Connect)
PWCH-AE (Pump down wet connect)
DWCH-SA(For slim hole)

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
