| A downhole system and method is disclosed for sealing a previously perforated section of casing and refracturing the subterranean formation in a region of the subterranean formation remote from those regions previously fractured. The system includes a truss structure radially expandable between a contracted configuration and an expanded configuration and a sealing structure disposed radially external to the truss structure. The truss structure and the sealing structure are set in their expanded configurations so that the sealing structure is put into engagement with the perforated section of casing so as to restrict the flow of fluids from the perforated section of production tubing into the subterranean formation. | ||||||

| A method of clearing well casing (3) or tubing from a target region of an oil/gas well (1) borehole is provided. The clearance of the oil/gas well bore hole being achieved by employing chemical agents (9) that consume, weaken or melt the well casing/tubing. In some aspects of the method the well casing is cleared to expose the rock formation within which the well borehole is formed so that the rock formation can be accessed from within the well casing/tubing. In other aspects of the method the removal of inner tubing structures is used to facilitate the unimpaired deployment of repair tools down the well borehole. | ||||||

| 224 | Settable well tool method | US14999637 | 2016-06-09 | US20160298413A1 | 2016-10-13 | Warren Lynn Frazier |
| A settable down hole tool is of increased drillability and/or of increased expansibility. The improvement in drillability can be caused by fracturing cast iron slips into a large number of small pieces that can be circulated out of a well without further reduction in size. The improvement in expansibility can be partially caused by providing an expander cone of increased hardness thereby allowing an increased angle on the expander cone and slips. The improvement in expansibility can be partially caused by increasing the thickness of the slips. | ||||||
