Abstract: Invention permits possible recompletion and rejuvenation of older wells to produce from new zones where the original zone of production has become too depleted for further production. Discloses a method and apparatus for testing an earth formation through a well bore side wall which is covered by steel casing and cement. Includes the steps of establishing a fluid tight seal between the face of the casing and the interior of tester apparatus; providing a source of change in the fluid pressure within the apparatus causing a pressure change only when such a fluid tight seal does exist; releasing a firing mechanism responsive to such fluid pressure change to fire a casing perforating mechanism; perforating a hole through the casing with the perforating mechanism at a position within the fluid tight seal to establish sealed fluid communication between the earth formation and the interior of the apparatus; and testing the earth formation through said hole.

Abstract: Discloses apparatus and method for testing, then treating, then testing the same sealed off region of earth formation within a well bore. Employs a sealing pad arrangement carried by the well tool to seal the test region to permit flow of formation fluid from the region. A fluid sample taking arrangement in the tool is adapted to receive a fluid sample through the sealing pad from the test region and a pressure detector is connected to sense and indicate the build up of pressure from the fluid sample. A treating mechanism in the tool injects a treating fluid into said sealed test region of earth formation. A second fluid sample is taken through the sealing pad while the build up of pressure from the second fluid sample is indicated.

Abstract: A well conduit caliper tool which simultaneously measures the remaining wall thickness of a well conduit in situ and the minimum inside diameter of such conduit. A caliper feeler arm element which extends out the furthermost distance from the caliper tool activates a sensing element that produces the indication of remaining conduit wall thickness. Another caliper feeler arm element which extends out the least distance from the caliper tool activates another sensing element that produces the indication of the minimum inside diameter. At the earth's surface these indications are recorded on a continuous strip chart or log as the variation of such respective diameters through the interval of conduit measured by the caliper tool. Mechanical linkage wear compensation and linear mechanical movement through the linkage between the feeler arm elements and the sensing elements are provided.In conjunction with the caliper tool is a diameter calibration apparatus and method including a calibration tube adapted to fit about the caliper tool at the earth's surface. The calibration tool provides designated simulated remaining wall thickness and simulated minimum internal diameters as standards from which the caliper tool is calibrated at the earth's surface.

Abstract: Improved end closures for shaped charge unit chambers in borehole perforating tools have flanged peripheral portions to be clamped in the threaded joint when sidewalls of adjacent chambers are threadedly joined. Also disclosed are sealing means for conductor wires passing through the end closures, which sealing means involves means for compressing and deforming the conductor insulation so that the conductors with their insulation sealingly occupy a predetermined space between surfaces of cooperating compressing and deforming means.

Abstract: For use with a core sample tool removing a sample from a formation of interest, a sonde supported sample receiving chamber is disclosed. It includes a main valve for sample insertion into a cavity in a resilient sleeve. The sleeve is in a chamber connected by suitable valved passages to enable ambient pressure at the cavity to equal downhole pressure; by valve operation this pressure can be maintained after chamber removal and transfer.

Abstract: A tool for testing earth formations in bore-holes provides a failsafe function for retracting the sealing pad of the formation isolation device, in the form of elements operable in response to failure of down-hole power supply for the tool to effect release of hydraulic setting pressure on the seal pad. The tool further provides a formation mini-sample chamber of variable volume with elements permitting aboveground monitoring and control of same independently of any other tool function. The mini-sample chamber control device also controls the operation of a formation fluid sample flow line valve. The tool is divided into upper and lower pivotable sections to alleviate the problem of becoming differentially stuck. A unique pivot structure incorporating sample chamber seal valve assembly, is provided. A unique sand screen device is provided to permit the tool to function when working with unconsolidated formations.

Abstract: A borehole televiewer system is disclosed which includes a sonde adapted to be suspended in a borehole containing borehole fluids. A variable speed brushless DC motor within the sonde is utilized to drive a rotatable mount at selected speeds in order to maintain a rotational speed in proportion to the linear speed of the sonde through the borehole. A "quick-disconnect" transducer head, including diametrically opposed acoustic transducers, is mounted to the rotatable mount in direct contact with the borehole fluids and is utilized to repetitively transmit energy pulses at the wall of the borehole throughout each rotation. Receiver circuitry is then utilized to determine the amplitude and transit time for each reflected pulse in order to determine parameters of interest for the borehole wall. In a preferred mode of the present invention, the reflected pulses are then utilized to generate a video representation of the borehole wall in addition to providing a graphic plot. A magnetic tape storage device may also be utilized to provide long-term storage of the resultant investigation.
