Core Sampling Techniques in Deepwater Exploration
Deepwater oil exploration demands special core sampling techniques. Core rig rise to the challenge.
- Pressure – Preserving Cores: Special tools keep cores under underground pressure. This stops volatile gases from escaping.
- Wireline Coring: Rigs lower tools on a wire instead of pulling the entire drill string. This cuts time in deep waters.
- Seabed Stabilizers: Rigs use anchors or suction pads. These keep them steady in rough ocean currents.
Deepwater reserves hold huge potential. But getting good core samples here is tough. These techniques, paired with robust rigs, make it possible. They help unlock the secrets of the ocean floor.
