LOOCH-M-2014 LOGGING-WHILE-DRILLING SYSTEM
The Systems are available in different diameters: LUCH-102 (4'') / LUCH-121 (4 3/4'') / LUCH-172 (6 3/4'') / LUCH-203 (8'')
Function of the System
LOOCH-102/LUCH-121/LUCH-172/LUCH-203 Logging-While-Drilling Systems are designed to survey wells with a diameter of 112 to 250 mm directly while drilling (LWD) and provide measurements of:
apparent electrical resistivity at two frequencies (6 probes for phase shift and 6 probes for attenuation)
specific resistivity of rocks by the Lateral Logging method with measurement of the developed view (image) upon 16 sectors
natural gamma-ray activity of rocks with measurement of the developed view (image) upon 16 sectors
hydrogen porosity by compensated Neutron-Neutron Logging
density of rocks by Gamma-Gamma Density Logging with measurement of the developed view (image) upon 16 sectors
The received information is recorded in a flash memory with data reference to the current time, and transmitted to the surface using a hydraulic pulser.
LWD Systems are equipped with the following set of sensors:

Description and operation of the System
The principle of operation of the System is based on the measurement and recording into the memory of geophysical parameters directly during drilling. When flushing is turned on, the flow sensor switches the System into operation. When flushing is turned off, a statistical measurement is performed. In the process of operation, all modules transmit information to the Memory and Measurement Module, where all the received information is continuously recorded with reference to time in flash memory. Part of the information is promptly transmitted to the Pulser Control Module, which in turn transmits it via a hydraulic channel to the surface. The set of data transmitted to the surface can be changed using the coded switching on/off the pumps.
The surface equipment extracts pressure modulation pulses and generates telemetric information transmitted by the pulser. The telemetry information received in real time is displayed on the tablet in the form of tables or well logs. The depth referencing system creates a "Depth—Time" file. At the end of drilling, data is readout from the Memory and Measurement Module, and the top-level program binds all measured parameters versus depth. After processing the data, the RealDepth5 software issues a standard LAS file for transmission to the geophysical service.
