Product Description
Drill String
-Purpose: Adds weight to the drill bit, keeping it in contact with the formation while providing stability to the drill string.
-Specifications:
1) Size: Outer diameters of 3-1/8" to 11", with standard lengths of 31 feet.
2) Material: Alloy steel with high yield strength.
3) Weight: Typically heavier than drill pipe (specific gravity around 7.8).
4) Thread Connections: API Regular or other premium threads.
-Features:
1) Spiral grooves for differential sticking prevention.
2) Non-magnetic drill collars (for sensitive directional tools).
Drill Pipe
-Purpose: Transmits torque and drilling fluid to the bottom hole while maintaining flexibility to accommodate wellbore curves.
-Specifications:
1) Size: Common outer diameters range from 2-3/8" to 6-5/8".
2) Material: High-strength steel grades like E75, X95, G105, and S135.
3) Wall Thickness: 0.280"-0.500".
4) Connections: Tool joints with API Regular, NC (Numeric Connection), or IF (Internal Flush) threads.
5) Standards: API 5DP or equivalent.

3) Wall Thickness: 0.280"-0.500".
4) Connections: Tool joints with API Regular, NC (Numeric Connection), or IF (Internal Flush) threads.
5) Standards: API 5DP or equivalent.
Drill Collar
-Purpose: Adds weight to the drill bit, keeping it in contact with the formation while providing stability to the drill string.
-Specifications:
1) Size: Outer diameters of 3-1/8" to 11", with standard lengths of 31 feet.
2) Material: Alloy steel with high yield strength.
3) Weight: Typically heavier than drill pipe (specific gravity around 7.8).
4) Thread Connections: API Regular or other premium threads.
-Features:
1) Spiral grooves for differential sticking prevention.
2) Non-magnetic drill collars (for sensitive directional tools).
Kelly
-Purpose: Provides torque from the rotary table to the drill string, essential for vertical drilling.
- Specifications:
1) Types: Square or hexagonal.
2) Size:
-Square Kelly: 3-1/2" to 6" across flats.
-Hexagonal Kelly: 3-1/2" to 6-5/8" across flats.
3) Material: High-grade alloy steel, heat-treated for durability.
4) Length: Typically 40 to 46 feet.
-Features:
1) Internal bores for fluid circulation.
2) Anti-corrosion coatings.
- Specifications:
1) Types: Square or hexagonal.
2) Size:
-Square Kelly: 3-1/2" to 6" across flats.
-Hexagonal Kelly: 3-1/2" to 6-5/8" across flats.
3) Material: High-grade alloy steel, heat-treated for durability.
4) Length: Typically 40 to 46 feet.
-Features:
1) Internal bores for fluid circulation.
2) Anti-corrosion coatings.
Heavy-Weight Drill Pipe (HWDP)
-Purpose: Acts as a transition between drill collars and regular drill pipe, reducing fatigue failure in the drill string.
-Specifications:
1) Size: Outer diameters of 2-7/8" to 6-5/8".
2) Wall Thickness: 1"-2".
3) Material: Premium alloy steel.
4) Length: Commonly 31 feet.
5) Thread Connections: NC or IF types.
-Features:
1) Internal and external upsets for increased strength.
2) Grooved or slick-body designs.
-Specifications:
1) Size: Outer diameters of 2-7/8" to 6-5/8".
2) Wall Thickness: 1"-2".
3) Material: Premium alloy steel.
4) Length: Commonly 31 feet.
5) Thread Connections: NC or IF types.
-Features:
1) Internal and external upsets for increased strength.
2) Grooved or slick-body designs.
