PILOT MWD
The Pilot Directional Module is a full-feature directional measurement device. It provides highly accurate Inclination (0°-180°),
Azimuth (0°-360°) and Tool Face measurements at all wellbore inclinations. It may be combined with a Gamma Ray sensor to provide formation logging information.
How does it work?
The measurements for borehole direction and angle are made using tri-axial Flux Gate Magnetometers and Q-Flex type Accelerometer packages respectively. These sensors provide very high accuracy measurements. A built-in temperature sensor enables appropriate corrections to be made to these measurements. Tool Face readings can be obtained from either the magnetometer or the accelerometer packages, according to borehole angle and/or operator choice. Local magnetic and gravity field values are recorded for survey quality control purposes. Pilot and WellTracer use the same battery power supply. This powers the sensor in the Pilot or WellTracer Directional Module (DM) and drives the Pulser. A single battery is often used in the WellTracer, whilst the Pilot system is frequently operated with two, in particular when longer operations are in order or when run in combination with gamma. For efficiency, power supply is switched to the second battery module after the first pack has been depleted. Battery cartridges are field-replaceable and are rated to 150°C.
What are the key features and benefits?
• High accuracy – offering operators maximum confidence
• Robust and reliable – capable of coping with extreme environments
• Speed – a streamlined and highly effective coding system allows fast transmission of data
• Ease of use – battery power makes it simple to use and enhances reliability
