| 20090114393 | DIVERTER VALVE - Apparatus for multi-zone wellbores that can by-pass upper hydrocarbon bearing zones and deliver fluid to lower hydrocarbon bearing zones. The apparatus can include at least one housing, and at least one port can be formed through the housing. An inner sleeve can be positioned within the housing. At least one cavity can be radially disposed on an outer diameter of the inner sleeve, and each cavity can be located within an annulus formed between the inner sleeve and the housing. A ball can be disposed within each cavity, and the ball can be adapted to selectively engage the port. | 05-07-2009 |
| 20100163235 | EFFICIENT SINGLE TRIP GRAVEL PACK SERVICE TOOL - A service tool and methods for performing subterranean hydrocarbon services in a wellbore. The service tool can include a body that having an aperture formed therethrough. A valve system can be connected to the body. The valve system can selectively form a flow path between a first portion of the aperture and a second portion of the aperture; a flow path between a first flow port formed through a first portion of the body, the aperture, and the outer diameter of the body; and/or a flow path between a channel formed in a portion of the body, a second flow port formed through a second portion of the body, and the second portion of the aperture. | 07-01-2010 |
| 20110146984 | CONSTANT PRESSURE OPEN HOLE WATER PACKING SYSTEM - A system for conveying fluid into a wellbore, including a tubular member, a packer, a hydrodynamic flow device, and a seal device. The tubular member is disposed in the wellbore through a first zone, a second zone, and a hydrocarbon producing zone of the wellbore. The packer is disposed adjacent to the tubular member, and is configured to at least partially isolate the hydrocarbon producing zone from at least one of the first and second zones. The hydrodynamic flow device is disposed around the tubular member and comprises a pump fluidly connected to a discharge in fluid communication with the first zone and an inlet in fluid communication with the second zone. The seal device is disposed around the hydrodynamic flow device to isolate a first annulus of the first zone from a second annulus of the second zone. | 06-23-2011 |
| 20120118564 | Erosion Tracer And Monitoring System And Methodology - A technique provides a system and methodology for detecting and monitoring erosion in various environments, including downhole environments. A tracer element is located in a component such that sufficient erosion of the component due to fluid flow exposes the tracer element. A monitoring system is disposed for cooperation with the tracer element such that exposure of the tracer element is detected by the monitoring system. The monitoring system outputs appropriate data indicative of the erosion to enable adjustments to the fluid flow. | 05-17-2012 |
| 20120298223 | PREMIUM MESH SCREEN - Systems and methods for preventing particles from flowing into a base pipe are provided. A base pipe can have a plurality of perforations formed radially therethrough. A filtering strip can be wrapped helically around an outer surface of the base pipe to cover at least a portion of the perforations. The filtering strip can include a drainage layer, a filter layer, and a shroud layer. The drainage layer can include a plurality of ribs in contact with the outer surface of the base pipe. The filter layer can be coupled to the drainage layer and include at least one mesh screen. The shroud layer can be coupled to the filter layer and include a perforated metal sheet. | 11-29-2012 |
