Claim 17:
18. A centralizer assembly for use in a wellbore, the centralizer comprising:
an elongated, primary tubular member extending along a centralizer axis, the primary tubular member having a first end and a second end and a tubular wall extending between the first and second ends, the tubular wall having an inner surface and an outer surface;
a first elongated centralizer strip assembly extending linearly along at least a portion of the primary tubular member so as to be parallel to the centralizer axis, the first elongated centralizer strip assembly having an outer portion adjacent the outer surface of the tubular wall and an inner portion adjacent the inner surface of the tubular wall where the inner portion and outer portion oppose one another on opposite sides of the tubular wall, the outer portion of the first elongated centralizer strip assembly having a first outer radial length and the inner portion of the first elongated centralizer strip assembly having a first inner radial length;
a second elongated centralizer strip assembly spaced apart from the first elongated centralizer strip assembly about a perimeter of the elongated, primary tubular member, the second elongated centralizer strip assembly extending linearly along at least a portion of the primary tubular member so as to be parallel to the centralizer axis, the second elongated centralizer strip assembly having an outer portion adjacent the outer surface of the tubular wall and an inner portion adjacent the inner surface of the tubular wall where the inner portion and outer portion oppose one another on opposite sides of the tubular wall, the outer portion of the second elongated centralizer strip assembly having a second outer radial length and the inner portion of the second elongated centralizer strip assembly having a second inner radial length; and
a third elongated centralizer strip assembly spaced apart from the first elongated centralizer strip assembly and the second elongated strip assembly about the perimeter of the elongated, primary tubular member, the third elongated centralizer strip assembly extending linearly along at least a portion of the primary tubular member so as to be parallel to the centralizer axis, the third elongated centralizer strip assembly having an outer portion adjacent the outer surface of the tubular wall and an inner portion adjacent the inner surface of the tubular wall where the inner portion and outer portion oppose one another on opposite sides of the tubular wall, the outer portion of the third elongated centralizer strip assembly having a third outer radial length and the inner portion of the third elongated centralizer strip assembly having a third inner radial length;
wherein the first outer radial length is greater than the second outer radial length and the third outer radial length, wherein the second outer radial length is greater than the third outer radial length; and
wherein the first, second and third inner radial lengths are the same.
