Well drilling fluids / sales & engineering

Drilling of various wells

 

More than 50 years have been passed since the first use of drilling fluids for a petroleum well in Japan .
At the time, drilling fluids were used only for removal of cuttings. However, at present various drilling fluids properties are required due to deep wells (>5,000m, >200 oC) and high angle or horizontal wells .
We, Telnite, are always trying hard to meet these difficult requirements , and are developing new chemicals for drilling fluids using our special technologies, as well as the optimized engineering services .
Drilling fluids are also used in the drilling of water wells, hot spring wells and various observation wells that are shallower in comparison with petroleum wells .
For these wells , we also provide economical and high performance drilling fluid systems and optimized engineering to meet customers' requirements.

Drilling fluid systems with high performance

 

We have the following drilling fluid systems with high performance for various wells .

 

Ultra high temperature drilling fluid system (Hipergel/G-500S mud system)
This system can be used for drilling deeper than 6,000m with a temperature of 210 oC or more .

 

Deep water drilling fluid system (NaCl-KCl/Polymer/PPG mud system)
This system can be used for offshore drilling with a water depth of 1,000m or more .

 

Simple drilling fluid system (EZ-Drill mud system)
This system can be used for drilling of water wells , hot spring wells and various observation wells because of the following reasons ;

Applications/functions
Stabilize water-sensitive formations .
Reduce bit-balling .
Increase rheological properties of drilling fluids .
Provide mud lubricity .
Flocculate drilled solids .

 

Advantages
