🔸 Sliding Mode Versus Rotating Mode 🔸 In sliding mode, the bend and bit are first oriented in the desired direction, then the downhole mud motor alone powers the bit, with no rotation of the drillstring above the bit. By contrast, in rotating mode, the drilling rig's rotary table or its top drive rotates the entire drillstring to transmit power to the bit. Comparing between sliding (steering) and rotating, sliding can create dog leg more than rotating because mud motor incorporating with bend housing is designed to directionally drill to the specified direction; however, when rotating, BHA is stiffer and has tendency to hold the direction. Rotating ROP is always faster than sliding ROP by these following reasons: 🔹Friction force exerts on stable drill string when steering is always more than rotating. 🔹 When steering, WOB is limited. Motor can be stalled or worn out if WOB excesses. 🔹 Direction of well must be controlled carefully that means well can not be drilled faster. #directionaldrilling #drillingengineering

This is possible with our hydrostatic rolling tools! These not only optimize external surfaces, but also drill holes. The tools, which are specially designed for drilling, adapt perfectly to the surface with their opposing rolling balls.

Trying to Enhance the performance of any Vibration tool in your drillstring? Are there continual issues with valving sections either breaking or failing while operating to achieve the most out of your tools? Element has the answer with our Vibration Enhancemnt Shock Tool (VEST) featuring the Pulse Enhancement Sub (PES). Combining high pump open force areas in the Shock Tool design along with the Pulse Enhancement sub that is open to both the annulus and pump open areas, the VEST greatly enhances the hitting force of the Vibration Tools allowing the operator to reduce the tight valving that can lead to premature failures and damages to drill string comments. contact us for more information! #vibrationtools #Shocktools #downholetools #ElementOilfieldTechnologies
