MWD service

Now, the LLC Logservice company, is actively engaged in introduction of MES systems on the market of oilfield services of Russia and the abroad.
To perform work on the transaction directional and horizontal wells, used equipment development, LLC "KARSAR" - "Navisky".

Telesystem Hung MWD provides reliable delivery to the surface in real-time downhole information, including the Zenith angle of the well, its azimuth and deflector position. This information, combined with drilling dynamics and exposure dose of natural gamma radiation, ensures accurate well positioning.

Description of the complex

Platform Naviskin based on the design of a probe that uses a standard non-magnetic drill pipe in conjunction with telemetry in hydraulic communication with the piston of the transmitter on the positive momentum. The pulsator module is equipped with an internal memory capable of continuously accumulating information from the sensors.



Pulsator:

Powered by two battery packs with automatic switching between them.
The operating time of the complex from one battery pack is 200 hours.

Battery module:

The external body of the probe with a diameter of 48 mm, equipped with replaceable centering units made of elastomer, allows working in standard non-magnetic drill pipes. Due to its small size, the Hitch probe can be used at all stages of drilling, changing, depending on the diameter of the tool, only the translator (UBHO). In addition, for correct operation at different flow rates of washing liquid pulsator and shoes (muleshoe) are equipped with carbide diaphragms of different diameters.

Resotel module induction logging
Measurement of real-time information about the resistance of rocks by the method of compensated midwater induction logging.  Registration of vibration, as well as in-line and in-line pressure Powered by the built-in battery pack. 
• Operating frequencies 2MHz and 400kHz 
• * Resistance range 0.1..1000 Ohm 
• Vertical resolution of 20cm 
• Operating temperature 150 deg. After 
• Hydrostatic pressure 100mpa

The design of the probe - extracted and equipped with a fishing head.


Ground equipment

The MTD hitch is designed for use with the ground-based Corsair Navigator equipment kit, in addition it is compatible with ground-based tensor equipment and software.

 

The Optimus Navigator software provides a full range of probe settings as well as the registration/visualization process during drilling.

    

Application of the complex

System Naviskin passed the entire set of experimental-industrial works on the fields of Russia and the near abroad. The total operating time is more than 1000 hours.  The equipment has established itself as a reliable complex in the construction of wells of varying complexity and profiles.
In the arrangement with the television system used NUBT imported Schoeller-Bleckmann Darron Russia.
Available nub versions Flex and Slick, 105 mm, 120 mm, 172 mm, 203 mm.
