    The monitoring of mechanical and hydraulic parameters while drilling provides information on the characteristics of the drilled layers. When drilling mud, it is standard practice to monitor the levels of the mud tanks (total losses, inflows) and the presence of gas. There are also devices for monitoring the chemical composition of the mud.

    In some cases, such as drilling steeply dipping formations or unpredictable deviation in conventional drilling operations, directional-drilling techniques may be employed to ensure that the hole is drilled vertically. While many techniques can accomplish this, the general concept is simple: point the bit in the direction that one wants to drill.

  • The Importance of Drilling Parameters - FordiaDiese Seite übersetzen

    CONCLUSION: Some core bits allow drillers to adjust drilling parameters more liberally. We've just launched the RockStar 9 core bit at this week's PDAC and it's a bit that provides a lot of versatility. By adjusting drilling parameters, the RockStar 9 allows drillers to increase penetration rate without sacing bit life.
