A gyroscopic survey is a method of determining the deviation of a wellbore path from the vertical plane using a gyroscope tool. It helps to ensure accurate wellbore placement. A magnetic survey utilizes magnetometers to measure the Earth's magnetic field to determine the wellbore's orientation in relation to the magnetic north, aiding in directional drilling operations.
The aims of a compass survey are to determine the magnetic bearing of a line and to set out accurate directions on the field. Its objectives include establishing a reference direction, determining the magnetic declination, and providing a basis for orienting maps and conducting navigation activities.
The magnetic bearing of a line in theodolite surveying is the horizontal angle measured clockwise from the magnetic north direction to the line. This bearing is used to orient the theodolite and accurately measure angles during surveying work. It is important to account for magnetic declination when converting magnetic bearings to true bearings.
The word is spelled "survey."
a survey
The plural of survey is surveys.
A magnetic compass uses the poles of our planet to stay in alignment. A Gyroscopic compass is set to a particular direction and tends to try to stay that way. After time, even the best Gyro will start to precess (move). This means the you will need to compare your Gyro to the magnetic every 15 minutes or so. Some modern gyroscopic compasses are capable of auto resetting to do this update automatically
Gyroscopic survey tools such as those manufactured by SPT are viewed as productivity and profitability tools, helping borehole operators attain targets within time and cost constraints. It is no secret mining companies are now extensively exploiting every site in an effort to make every mine profitable. SPT surveying instruments have proved invaluable in such cases due to their well known reliability, repeatability of results, speed and consistency. Previous generation magnetic sensor based instruments simply cannot work in such conditions while the true north seeking gyroscopic survey tool works regardless of geological formations or the presence of magnetic disturbances in the form of nearby boreholes.

The US Navy while performing a careful survey of magnetic compass anomalies in the early 1950s to improve navigation. The data and the survey was originally classified.
The plane in which the reactive gyroscipic couple acts is called the gyroscopic plane
principle of gyroscopic couple ? how gyroscopic coule work in a aroplanes & ship ?
If the precessionnal motion is caused by applying gravitational torque,it is called gyroscopic motion.

A spinning top has a gyroscopic effect that is resistant to changing its axis (falling over). The faster the top, the stronger the gyroscopic effect. As the top begins to slow due to friction, the gyroscopic effect weakens and the top begins to fall.
North seeking gyro is the best gyroscopic surveying instrument for the mining and Oil & Gas industries. As it is a North-Seeking Gyro, all measurements are in reference to geographic North. Unlike other downhole survey or magnetic tools, it is not affected by magnetic interference. When it comes to directional surveying where precision and accuracy are of paramount importance, especially in areas with strong magnetic influences, true North-seeking gyro while drilling is the only solution. It can run inside casing without worrying about the magnetic influences causing deviations and errors.SPT true North-seeking gyro while drilling uses quartz technology, more rugged and highly precise in operation.
