Study Notes
Downhole Tools in Drilling
- Downhole tools are crucial for efficient drilling operations, supporting various functions within the borehole.
- Common tools include a drilling motor, which enhances the rate of penetration into the ground.
- A rotary steerable system allows for precise directional control during drilling, improving accuracy in reaching targets.
- Specialized subs and collars serve multiple purposes, including:
- Measurements to evaluate geological conditions and drilling performance.
- Borehole enlargement to increase the diameter of the borehole for specific applications.
- Circulation to maintain fluid flow during drilling, which cools the drill bit and removes cuttings.
- A drilling jar is utilized to alleviate issues when the Bottom Hole Assembly (BHA) becomes stuck, allowing for recovery and continued operation.
Logging While Drilling (LWD) Systems
- Utilized for formation evaluation during drilling operations.
- Provides real-time data on geological formations.
Coring Bottom Hole Assemblies (BHAs)
- Comprised mainly of a core barrel and supporting equipment.
- Designed to extract core samples from underground formations.
Agitator™ Systems
- Employed to enhance weight transfer during drilling.
- Improves drilling efficiency and stability.
Directional Wells
- May incorporate a downhole motor or rotary steerable system for maneuvering.
- Equipped with Measurement While Drilling (MWD) tools to assess inclination and azimuth.
- MWD tools facilitate data transmission to the surface for ongoing analysis.
