Abstract: A method and system for improving borehole image forward modeling of formation properties is disclosed. An imaginary circle (106) having a plurality of bins (202) is centered at a location of interest at an axial position along the target wellbore (102). The imaginary circle is perpendicular to an axis (110) of the target wellbore and represents a region of the formation to be analyzed. A pseudo log relating to the parameter of interest at the axial position along the target wellbore is then determined. The pseudo log comprises at least a value for the parameter of interest at a desired point corresponding to one of the plurality of bins. The determined pseudo log is then visualized.

Abstract: A chuck is provided with a body, a plurality of jaws and an adjustment ring. The adjustment ring is threadably engaged with the jaws. When the adjustment ring is rotated in one direction, the jaws tighten by moving closer to each other. When the adjustment ring is rotated in the opposite direction, the jaws loosen by moving away from each other. An impact member is also provided for engagement with the adjustment ring. When the drive shaft of the power tool is rotated, the adjustment ring impacts against the impact member. As a result, the adjustment ring and the body of the chuck rotate relative to each other causing the jaws of the chuck to loosen or tighten depending on the direction the drive shaft is rotating.
