Abstract: An apparatus for positioning a well instrument in the proper position in a bore hole for performing a desired well operation. Each end of a coiled spring is attached to the body of the well instrument. The coiled spring projects outward at right angles to the body of the well instrument and contacts the wall of the bore hole insuring that the well instrument is in the proper position for performing the desired well operation. When used with a sidewall sampler the coiled spring absorbs recoil energy when the sampling guns are fired. When the well instrument is being moved through restrictions in the bore hole, the coiled spring will deflect along the side of the well instrument allowing the well instrument to easily pass through the restriction.

Abstract: An apparatus is provided for positioning a well instrument in a well in the proper position for a well operation. An annular movable element is positioned encircling the well instrument housing. A movable arm is connected to the well instrument housing by a pivot that allows the movable arm to turn relative to said instrument housing. One end of the movable arm is linked to the annular movable element so that said end of the movable arm moves with the annular movable element. A spring encircles the well instrument housing and is connected between the well instrument housing and the annular movable element. A release element allows the force of the spring to move the annular movable element causing the movable arm to pivot and thereby extend the other end of the movable arm until it contacts the wall of the well and places the well instrument in the proper position for the desired well operation.
