| 20080314591 | SINGLE TRIP WELL ABANDONMENT WITH DUAL PERMANENT PACKERS AND PERFORATING GUN - A method of abandoning a well includes the steps of: assembling a tool string including a perforating gun interconnected between first and second packer assemblies; conveying the tool string into a wellbore in a single trip into the wellbore; setting the first packer assembly; setting the second packer assembly; firing the perforating gun; and flowing cement into an annulus longitudinally between the first and second packer assemblies. A system for abandoning a well includes a tool string configured for conveyance into a wellbore in a single trip into the wellbore, the tool string including a perforating gun interconnected between first and second packer assemblies, each of the first and second packer assemblies including a permanent packer. | 12-25-2008 |
| 20100071895 | System and Method of Controlling Surge During Wellbore Completion - A downhole oilfield completion method is provided. The method comprises determining a surge profile for a wellbore and assembling a downhole completion tool having an interior surge volume and comprising a surge attenuation system operable to reduce a surge of the downhole completion tool based at least in part on the surge profile. The method also comprises running the downhole completion tool into the wellbore and surging the wellbore by admitting wellbore fluid into the interior surge volume, the surge reduced at least in part by the surge attenuation system. | 03-25-2010 |
| 20100133004 | System and Method for Verifying Perforating Gun Status Prior to Perforating a Wellbore - A system for verifying perforating gun status prior to perforating a wellbore. The system includes a perforating gun ( | 06-03-2010 |

| 20110108263 | Managing Pressurized Fluid in a Downhole Tool - A wellbore apparatus includes a connector sub assembly having a body, the body having a first end adapted to couple to a first perforating sub component and a second, axially opposed end adapted to couple to a second perforating sub component. The connector sub body defines a cavity proximate the second end of the connector sub body; and a flow path in fluid communication with the cavity and a location exterior to the wellbore apparatus. The apparatus includes a valve residing in the flow path and actuatable to block or allow fluid flow from the cavity, through the flow path, to the location exterior to the wellbore apparatus. | 05-12-2011 |
| 20110120695 | PERFORATING GUN GRAVITATIONAL ORIENTATION SYSTEM - A perforating gun gravitational orientation system includes a perforating gun and a swivel device connected to the perforating gun to permit rotation of the perforating gun within casing, and the perforating gun spaced apart from the casing by the swivel device. Another perforating gun gravitational orientation system includes the swivel device having an axis of rotation which is spaced apart from a center of gravity of the perforating gun. Yet another perforating gun gravitational orientation system includes the swivel device having an axis of rotation which is spaced apart from a center axis of the perforating gun. | 05-26-2011 |
