Study Notes
Overview of Directional Drilling
- Directional drilling involves navigating a wellbore along a specific path to reach a targeted location.
- It allows for complex drilling angles to be achieved, maximizing resource extraction and minimizing surface impact.
Application of Directional Drilling
- Essential for offshore field development, enabling access to underwater oil and gas reserves.
- Utilized in drilling through thin reservoir layers, optimizing resource recovery.
- Facilitates multiple well placements from a single drilling location.
- Enhances environmental protection by reducing surface disturbance.
- Supports horizontal drilling, increasing contact with the reservoir for higher production rates.
- Used in urban areas to drill beneath structures while minimizing disruption.
- Effective in drilling complex geology where vertical drilling is not feasible.
Deflecting Tools
- These tools are crucial for altering the path of the drill bit to achieve directional drilling.
- Various types of deflecting tools can be used depending on the drilling requirements.
- They assist in building angles, maintaining directional hold, and adjusting trajectories as needed.
- Proper selection and use of deflecting tools directly impact drilling efficiency and success.
