Borehole Deviation Surveys
Borehole deviation surveys are used to accurately determine the trajectory of a borehole, including the borehole axis, inclination, and direction. Depending on project requirements, these measurements are taken at specific intervals, typically every 5 to 10 meters.
Purpose and Benefits
– Precise Borehole Guidance: Ensures that the borehole follows the planned path, especially critical for directional drilling.
– Monitoring Inclination and Direction: Provides vital information to detect and correct deviations early.
– Enhancing Geological Interpretation: The survey results contribute to more accurate interpretation of geological data and improve the precision of geological models.
Application
The results of borehole deviation surveys are particularly valuable for geological data evaluation and for guiding and controlling the drilling process. This is especially useful for directional drilling to ensure that the target area is accurately reached.
