The HIGH
SIDE SEEKER® Like its big brother,
the MI3 survey tool, the HIGH SIDE SEEKER® is an electronic multishot tool
- it operates in the same way as the MI3 with the exception that it has no
azimuth sensor.
The HIGH SIDE
SEEKER® contains a three-component accelerometer package, so that it can
provide dip and gravitational high side (toolface or roll orientation) in all
orientations. High side is measured relative to a location mark on the
instrument barrel.
The HIGH SIDE
SEEKER® has a variety of applications. For example:
- electronic dip meter.
- high side determination for core orienting work.
- complementing data from other downhole geophysical tools.
- high side determination for legacy survey tools.
The HIGH SIDE SEEKER® can be configured in a number of ways to
suit different applications. It is capable of communicating with computers or
PDA's over a serial and/or IrDA interface. It can be fitted with a backlit LCD
display to show results on-the-fly, in which case user input is through a
combination rotary and pushbutton switch. Custom interfaces are also
available.
The image below shows the HIGH SIDE SEEKER® displaying an
inclination of 88.3 degrees from vertical (oilfield convention) and a toolface
of 111.5 degrees.
 In addition to operating as a multishot instrument, the HIGH SIDE
SEEKER® is also capable of taking an external trigger input. For example, a
pressure sensor or impact sensor can be used to trigger a reading which is
stored together with a time stamp.
Configuration: Depending on the application, the HIGH SIDE
SEEKER® is run with shock absorbers, pressure housings, and/or thermal
shields.
