🔸 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

Drilling is a cutting process where a drill bit is spun to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multi-point. The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute. How to drill a Hole? Step 1: Measure and Mark. Measure the location of the hole. Step 2: Center Punch. A center punch makes a small dent in the surface of the material that prevents the drill from wandering when it first contacts the surface. Step 3: Set Up. Step 4: Drill and pour some water (mix with chemicals) to save the drill bit from burnt Step 5: Clean Up the Hole.. Step 6: Clean Up the workpiece....

Using flow drilling and tapping, we create threaded bushes in thin-walled tubes, eliminating the need for inserts or welded bosses. This process forms a bush with 300% greater depth than the tube thickness, allowing for strong, reliable threads. https://lnkd.in/eY-wPETZ #FlowDrilling #ThreadedBushes #TubeInnovation
