20100084145 | Multiple Activation-Device Launcher For A Cementing Head - The invention relates to a multiple activation-device launching system for a cementing head, comprising a launcher body comprising at least one launching chamber and a device chamber, the launching chamber sized to receive one or more activation devices therein, the launching chamber in fluid communication with a power source for launching the activation device into the device chamber. Then the invention relates to various methods involving such system. | 04-08-2010 |
20100175891 | DART LAUNCHER FOR WELL CEMENTING OPERATIONS - Modular apparatus for remotely activating a wiper plug launching tool or other down-hole equipment by launching a dart or other projectile along tubing to the subsea equipment. A dart is loaded into a basket prior to launch and subsequently loaded into a modular tool piece. The pre-loaded tool pieces are configurable prior to use dependent on operational requirement and furthermore may be independently removable from the remaining equipment facilitating maintenance and serving of individual tool pieces. | 07-15-2010 |
20100282478 | Activation-Device Launcher For A Cementing Head - The present invention relates in general to equipment for servicing subterranean wells and in particular to a cementing head that is intended to drop a combination of darts, balls, bombs and canisters in order to activate downhole equipment, launch cementing plugs, deliver chemical products, or the like. | 11-11-2010 |
20110146986 | EQUIPMENT FOR REMOTE LAUNCHING OF CEMENTING PLUGS - An apparatus for remotely launching cementing plugs is configured such that the length of a dart is not necessarily the same as the corresponding plug to be launched. Such a design presents operational and ergonomic advantages, particularly in an offshore environment. Methods for launching cementing plugs and cementing a subterranean well are also presented. | 06-23-2011 |
20110247834 | MULTIPLE ACTIVATION-DEVICE LAUNCHER FOR A CEMENTING HEAD - The invention relates to a multiple activation-device launching system for a cementing head, comprising a launcher body comprising at least one launching chamber and a device chamber, the launching chamber sized to receive one or more activation devices therein, the launching chamber in fluid communication with a power source for launching the activation device into the device chamber. Then the invention relates to various methods involving such system. | 10-13-2011 |
20120000675 | MULTIPLE ACTIVATION-DEVICE LAUNCHER FOR A CEMENTING HEAD - The invention relates to a multiple activation-device launching system for a cementing head, comprising a launcher body comprising at least one launching chamber and a device chamber, the launching chamber sized to receive one or more activation devices therein, the launching chamber in fluid communication with a power source for launching the activation device into the device chamber. Then the invention relates to various methods involving such system. | 01-05-2012 |
20120097394 | MODULAR DART LAUNCHING VALVE - The present invention relates in general to equipment for servicing subterranean wells and in particular to a cementing head that is intended to drop a combination of darts, balls, bombs and canisters in order to activate downhole equipment, launch cementing plugs, deliver chemical products, or the like. A cementing head comprises a modular valve apparatus, comprising at least two detatchable parts. This arrangement allows the operator to remove and disassemble the valve apparatus at the wellsite. Thus, repairs and maintenance may be performed at the wellsite and the valve apparatus may be reassembled and reinstalled, obviating the need to transport the equipment to a central facility. | 04-26-2012 |
20120160482 | Damper Cartridge For Launching Plugs In Cementing Operations - An apparatus for use in launching cement plugs in a well cementing operation, comprising: a cylinder ( | 06-28-2012 |
20130037258 | Activation-Device Launcher For A Cementing Head - An activation-device launching system, mounted on a cementing head, allows the deployment of a combination of darts, balls, bombs, canisters in order to activate downhole equipment, launch cementing plugs, deliver chemical products, or the like. A valve controls the flow of process fluid, and holds an activation device in place until it is time for launching. The valve also has a hollow axle through which balls may be launched into the process-fluid stream at any time. | 02-14-2013 |
20130140025 | Equipment for Remote Launching of Cementing Plugs - An apparatus for remotely launching cementing plugs is configured such that the length of a dart is not necessarily the same as the corresponding plug to be launched. Such a design presents operational and ergonomic advantages, particularly in an offshore environment. Methods for launching cementing plugs and cementing a subterranean well are also presented. | 06-06-2013 |
