Certainty in wellbore position for precise well placement & anticollision

Directional surveys are perhaps the most valuable measurement taken for drilling operations. Without accurate and properly maintained surveys, the risk of colliding with another well increases significantly. Schlumberger provides advanced surveying services that enhance the output of traditional MWD tools to improve safety and efficiency in drilling. WellDefined drilling survey services reduce drilling and geological risk by increasing drilling efficiency and providing the level of well placement accuracy required to prevent geological sidetracks.

WellDefined services are designed to specifically help operators achieve their well placement objectives in all environments.
