When a well plan dictates the drilling of a straight borehole, surveys are periodically taken to ensure that it will hit its target and does not trespass underneath different property lines. The survey tool usually run inside the drill string attached to a wire on a wireline unit or is launched in front of the drill bit.
To determine the exact location of the bore hole path is crucial to ensure the drill plan reflect the situation in the field. The survey can thus be considered as the most important task in a drilling program. A survey tool can monitor the hole as it goes, keep track of Dog Leg Severity (DLS) as well as position of the hole at any give depth. Thus giving vital information to make qualified decisions.
