| 20140262214 | Bonded Segmented Slips - A slip assembly for a downhole tool, such as a bridge plug, has a slip body composed of independent segments. The segments are affixed together along their longitudinal sides by a bond, which can be composed of thermoplastic or thermoset resins, an elastomer, epoxy adhesives, bonding agent manufactured using ceramic, metallic agent, or a combination of these. The surface area over which the bonding agent is applied can be controlled for a particular implementation. Thus, more or less of the longitudinal sides of the segments can be bonded to other segments. This provides greater control of the required force to break the bond itself, which can be tailored as desired. | 09-18-2014 |

| 20130000472 | MULTI-LAYERED PERFORATING GUN USING EXPANDABLE TUBULARS - A perforating gun body including a first layer having a first yield strength and a second layer having a second yield strength, the second layer positioned radially inwardly from the first layer with a radial gap initially provided between the first and second layers, the second layer expanded radially to engage the first and second layers, the first and second yield strengths being dissimilar. | 01-03-2013 |
| 20130092378 | SELECTIVELY FIRED HIGH PRESSURE HIGH TEMPERATURE BACK-OFF TOOL - A method for unseating a threaded connection of wellbore tubing within the wellbore. The method utilizes a back-off tool which consists of a tubular metal housing, a shaped charge and HNS detonating cord within the housing, and an explosive material attached to the housing. The back-off tool is detonated near the threaded connection, creating a shockwave that strikes the threaded connection with sufficient force to unseat the connection. | 04-18-2013 |

| 20150368994 | Inserts Having Geometrically Separate Materials for Slips on Downhole Tool - A downhole tool, such as a fracture plug used during a fracture operation, installs in a downhole tubular, such as casing. The tool has a mandrel with a sealing element disposed thereon between uphole and downhole ends. Slip assemblies on the mandrel can be moved to engage the downhole tubular. When the tool is used as a bridge plug, the uphole assembly supports the sealing element compressed, and the downhole assembly supports fluid pressure downhole of the tool. The slip assemblies have inserts composed of at least two materials that are different from one another and are geometrically separate from one another. In addition or as an alternative, the slip assemblies can be composed of at least two different materials that are geometrically separate from one another. | 12-24-2015 |

| 20160061000 | Flow Resistant Packing Element System for Composite Plug - A downhole tool, such as a composite bridge plug, has a packing element disposed on a mandrel of the tool adjacent an activating element, such as a cone and slip arrangement. The packing element includes a packer and at least one backup ring. The packer is composed of packing material and is compressible on the downhole tool at least in part due to the activating element. The at least one backup ring limits extrusion of the packer. The at least one backup ring is molded into the packing material at one end of the packer adjacent the activating element. Preferably, each end of the packer has at least two backup rings molded therein, and slots in the adjacent backup rings are preferably offset at the ends. | 03-03-2016 |
