suunamõõtmistest

Suunamõõtmised, known in English as directional measurements or directional surveying, are a crucial technique in the oil and gas industry, as well as in other subsurface exploration and resource extraction sectors. This process involves determining the precise path and orientation of a wellbore as it is drilled into the Earth. The data gathered from suunamõõtmised is essential for accurately mapping underground reservoirs, ensuring that exploration or production wells reach their intended targets, and avoiding collisions with existing wells.

The core of suunamõõtmised relies on specialized instruments called survey tools. These tools are lowered into the wellbore at regular intervals during the drilling process. Modern survey tools typically employ a combination of accelerometers and magnetometers to measure the inclination (the angle of the wellbore relative to the horizontal plane) and azimuth (the direction of the wellbore relative to magnetic or true north) at various depths. Some advanced systems also incorporate gyroscopes, which are not affected by magnetic interference, for even greater accuracy, especially in areas with significant magnetic anomalies.

The data collected from these measurements is then processed to construct a three-dimensional model of the wellbore's trajectory. This information is vital for geological interpretation, reservoir management, and for optimizing the placement of multiple wells within a field. Without accurate suunamõõtmised, the efficiency and safety of subsurface operations would be significantly compromised, leading to potential economic losses and operational risks.
