摘要：
Wellbore isolation devices may be produced with wear bands and slips having modified surfaces to change the frictional properties between these components and the surrounding wellbore surface. A wellbore isolation device may include: a mandrel； slips disposed circumferentially about the mandrel and in a first position along the mandrel. The slips comprise particles coupled thereto forming a modified surface. The particles comprise at least some sharp protrusions. At least one packer element is disposed along the mandrel and in a second position along the mandrel.
