- Core orienting
Software Options
MI3 tools come standard with software for Palm™, Windows™, and DOS™. Data collection and tool operation can be performed with a Palm™ Pilot, ruggedized field computer, or laptop computer.
Slimline Design
The deviation tool is available in a standard 25.4mm version (650m pressure rating), or a 33.4mm version with integral pressure barrel (3500m pressure rating). A pressure barrel is available for the 25.4mm tool.
Instant Results
Our borehole inclinometer uses data from a miniature three-axis fluxgate magnetometer and a three-axis accelerometer to determine the instrument orientation in space. The inclinometer operates in any orientation. Data are recorded electronically and results are available in real time (for cable operation) or shortly after the instrument is retrieved (singleshot and multishot operation). There are no films to develop and read, and there is no error-prone manual data entry to perform.
Magnetic Diagnostics
The MI3 series inclinometers have other advantages over film and gyro systems besides rapid data acquisition: the probes report on local magnetic dip and magnitude - such information can aid the operator in discarding data disturbed by local magnetization and can aid the geologist in analyzing the geology. The data also indicate whether the probe was stationary during the reading.
The inclinometer produces 26 different output parameters, including dip, azimuth, field strength, magnetic dip, magnetic toolface (high side), gravity toolface, and temperature.
Specifications
Every MI3 tool can be operated in a single-shot, multi-shot, or wireline mode. In multi-shot mode, coupled with a battery pack, as many as 7200 data stations can be recorded without any electrical connection to the instrument (batteries are readily-available AA cells). In wireline mode, a single conductor cable (as long as 10km) connects the MI3 to a computer that displays survey results in real-time. In any mode, you can choose where and how often you want to stop and take readings.
