| Detailed Description of the three types Steel Tooth Bits |
| 1. Elasatomer Sealed Roller Bearing Bit |
| Cutting Structure |
The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel Tricone bit. |
| Gauge Structure |
Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life. |
| Sealed Bearing Structure |
1.Abrasion resistance and seizure resistance of the bearing are improved.
2.Premium O-ring, Optimal seal compression and curved seal structure can enhance the seal performance. |
| Main Type Available |
Size: 5 7/8",6",6 1/2",7 1/2",7 7/8",8 1/2",9 1/2",9 5/8",9 7/8",12 1/4",13 5/8",14 3/4",15",15 1/2",17 1/2",22",24",26", etc.
IADC Code:1-- Series, 2-- Series,3-- Series |

| 2. Air Cooling Roller Bearing Steel Tooth Bit |
| Cutting Structure |
The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel Tricone bit. |
| Gauge Structure |
Gauge protection with gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability. |
| Sealed Bearing Structure |
Air cooling roller bearing package. Balls lock the conewhich reduces the probability of cone-dropping to minimum. |
| Main Type Available |
Size: 5 7/8",6",6 1/2",7 1/2",7 7/8",8 1/2",9 1/2",9 5/8",9 7/8",12 1/4",14 3/4",17 1/2", etc.

| 3. Non-Sealed Roller Bearing Steel Tooth Tricone bit |
| Cutting Structure |
The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces. |
| Bearing Structure |
Non-sealed roller bearing. Drilling fluid can enter the bearing directly for cooling; Balls lock the cone which reduces the probability of cone Cdropping to minimum. |
| Main Type Available |
Size: 2 3/8",3",3 5/8:",3 7/8",4",4 1/2",4 5/8",4 3/4",6",6 1/2",7 1/2",7 7/8",8 1/2",9 1/2",9 5/8",9 7/8",10 5/8",12 1/4", 17 1/2",etc.

| 4. Optimal Tricone bit well placement improves heavy oil production |
| Cutting Structure |
Girasol lies in the Middle Magdalena Valley basin. One of the largest heavy oil fields in Columbia, it is operated by Tricone bit, a joint venture of Sinopec and ONGC, in an equally shared association with Ecopetrol, Colombia’s national oil company. |
| Bearing Structure |
Tricone bit field is composed of a shallow sequence of sediments of fluvial origin, in which sandstone channels contain heavy oil with gravity ranging from 11 to 13° API. The main targets are five stacked, unconsolidated sand reservoirs, ranging in thickness from 10 to 30 ft (3 to 9 m). |
| Main Type Available |
Nearby heavy oil fields with similar characteristics are being produced using cyclic steam stimulation (CSS or “huff and puff”) thermal recovery techniques applied in vertical or deviated pdc Tricone bit wells. CSS uses the same wells for both steam injection and production. First, steam is injected for a period of time — typically several weeks — to heat the reservoir and reduce oil viscosity. Flow is then reversed to produce heavy oil through the same well. This role-switching continues cyclically over the economic life of the production system. |
