| 20090200084 | Injection System and Method - An injection system and method is described. In several exemplary embodiments, the injection system and method may be a part of, and/or used with, a system and method for excavating a subterranean formation. | 08-13-2009 |
| 20090090557 | Injection System And Method - An excavation system for forming a wellbore through a subterranean formation, the system employing pressurized drilling fluid with impactors mixed therein. The pressurized fluid with impactors is directed to a drill string having a drill bit with nozzles on its lower end. The fluid impactor mixture is discharged from the nozzles and against the formation, wherein the impactors contact, compress, and fracture the formation to excavate through the formation. The system includes an impactor injection system that injects impactors into a stream of pressurized drilling fluid to form the mixture. The injection system operates at substantially the same pressure as the pressurized drilling fluid. | 04-09-2009 |
| 20090038856 | Injection System And Method - An injection system and method is described. In several exemplary embodiments, the injection system and method may be a part of, and/or used with, a system and method for excavating a subterranean formation. | 02-12-2009 |
| 20080230275 | Impact Excavation System And Method With Injection System - A system and method according to which at least one vessel injects a suspension of liquid and a plurality of impactors into a formation to remove at least a portion of the formation. | 09-25-2008 |
| 20080210472 | Impact Excavation System And Method With Particle Separation - A system and method for excavating a subterranean formation, according to which a suspension of liquid and a plurality of impactors are introduced into at least one cavity formed in a body member and are discharging from the cavity so that the impactors remove a portion of the formation. The impactors are separated from at least a portion of the fluid, and are passed to a conduit so that the impactors accumulate in the conduit before being removed from the conduit. | 09-04-2008 |
