Directional drilling is defined as the practice of controlling the direction and deviation of a wellbore to a predetermined underground target or location. The most significant directional drilling challenge identified by operators drilling unconventional wells has been the inability to consistently follow a prescribed well path and to hit and stay within the targets identified during the well planning process. Inaccurate directional drilling routinely leads to hundreds of thousands of dollars of lost production value per well.

 

Challenges of directional wells:

  • Increased tortuosity of the final wellbore resulting in increased drilling times
  • Increased stress on downhole equipment leading to tool failures
  • Increased torque and drag
  • Loss of directional toolface control

 

Horizontal and multi-lateral wells are used to enhance reservoir contact and ultimately improve well performance. But understanding the particular challenges of directional drilling is essential to getting the most from these wells.

Challenges of horizontal wells:

  • Hole cleaning
  • Excessive drag and torque limitations
  • Weight on Bit
  • Directional control
