Magnetic Single Shots

The Magnetic Single Shot survey (MSS) is an accurate field-proven instrument measuring inclination and magnetic azimuth, which consists of an electronic timer, camera and combined compass / inclinometer. The instrument is run in the same way as the TOTCO.

When the timer fires, a film disc is exposed to the angle unit, thus recording the survey.

For vertical wells and possibly shallow directional wells, the tandem stack magnetic single shot (run with two instruments) should be used if MWD tools are not run.

The Magnetic Single Shot survey should be . . .
