  • Patent number: 7703538
    Abstract: Access to a downhole tool through a tubular wall is created with a penetration tool into a surrounding annular chamber. The chamber is disposed around a tool joint between the end connection leaving an annular chamber that is of considerable length and allowing penetration anywhere along such length. The need to precisely position the penetration tool, as in past designs of annular chambers disposed within a pin and box connection is eliminated. Landing shoulders for the penetrating tool are also not required as the long length of the annular chamber allows surface personnel to sufficiently and accurately place the penetration tool somewhere along the length of the annular chamber.
    Type: Grant

  • Patent number: 4062568
    Abstract: The method of the present invention comprises placing a test result printout on a work sheet having a grid thereon comprising a vertical and horizontal matrix of columns and rows. The rows are sized and spaced to register with the individual indicia in the column of indicia on the test printout. After the indicia on the test printout are aligned and registered with the horizontal rows on the work sheet, the indicia are transcribed from the printout to the work sheet. A data slip is then laid over the work sheet. The data slip has a horizontal row of boxes sized and spaced to register with a group of columns on the work sheet. The data slip is positioned so that the row of boxes is adjacent one of the horizontal rows on the work sheet and is registered with the columns within said group. The indicia in the columns are then transcribed from the columns to the boxes.
