| 20100294507 | PLUNGER LIFT - In a hydrocarbon producing wellbore, liquids (oil, condensate, water of mixtures thereof) from the formation may accumulate and build up a hydrostatic pressure gradient, which can kill gas production. Various embodiments of the present invention include a plunger lift system that can remove said formation liquids from a wellbore. A piston, including a sleeve with a hollow passage may travel downhole, accumulate formation liquids and utilizing the gas pressure deliver said formation liquids to the top of the wellbore for removal. The piston face may be one single wall that closes the hollow passage or the piston face may be comprised of a plug and an seat that unite to form a complete piston face downhole. Aspects of the plunger lift system, for example the sleeve and or the plug may be at least partially formed from materials that are buoyant in the formation liquids. | 11-25-2010 |
| 20100236781 | METHOD AND APPARATUS FOR PERFORATING MULTIPLE WELLBORE INTERVALS - A bottom hole assembly for one trip perforating and treating a wellbore, the bottom hole assembly including: a tool body including an outer surface and an upper end; a fluid passage extending into the tool body from the upper end; a valve to provide (i) in one orientation fluid access from the fluid passage to an outlet port opening to the outer surface and (ii) in another orientation fluid access from the fluid passage to a perforating gun actuation fluid supply channel while sealing fluid access from the fluid passage to the outer surface; an annular sealing member encircling the outer surface below the outlet port; and a perforating gun carried below the resettable, annular sealing member and hydraulically actuable to detonate by fluid communication through the perforating gun actuation fluid supply channel. | 09-23-2010 |
| 20100051278 | PERFORATING GUN ASSEMBLY - A perforating gun assembly including: an upper end; a perforating gun connected to the upper end; a hydraulically actuated tool connected to the perforating gun on an end opposite the upper end; and a fluid conduit extending through the upper end and to the hydraulically actuated tool, the fluid conduit allowing fluid communication past the perforating gun to the hydraulically actuated tool such that fluid can be communicated through the upper end to actuate the hydraulically actuated tool. | 03-04-2010 |
