Abstract:
An apparatus insertable into a wellbore for engaging a hollow tool body with a downhole wellbore surface, comprising:a slip engaged with the body and intersected by a longitudinal axis through the tool body, wherein said slip is axially and radially moveable relative to said longitudinal axis;a gripping surface on said slip for engaging the wellbore surface to prevent relative movement therebetween after said slip is moved radially from the longitudinal axis;an interior surface on said slip for defining a hollow space about the longitudinal axis when said gripping surface engages the wellbore surface; andmeans for moving said slip from said position proximate to said longitudinal axis until said gripping surface engages the wellbore surface, wherein said hollow space defined by said slip interior surface provides an unobstructed path through the tool body when said slip gripping surface engages the wellbore surface.
