| 20100122810 | WELL SCREENS AND METHOD OF MAKING WELL SCREENS - Screens and methods of making screens for use in a well for producing fluids from an underground reservoir are provided. In one example, the screen includes first and second sections of mesh tube that radially encircle a base pipe and that filter a flow of reservoir fluids into the base pipe. The first section has an end portion and the second section has an end portion. The end portions are connected together by a lap joint. | 05-20-2010 |

| 20090218101 | APPARATUS AND METHOD FOR INFLOW CONTROL - An inflow control assembly. The inflow control assembly can include an inner tubular member comprising a hole formed therethrough. A cover assembly can encircle the hole. The cover assembly can include a first outer member disposed about at least a portion of the inner tubular member. The first outer member can be secured to the inner tubular member. A second outer member can be disposed about at least a portion of the inner tubular member, and the second outer member can be secured to the inner tubular member. A screen portion can be disposed between the outer members and between the inner tubular member and the outer members. An annulus can be formed between the outer members and the inner tubular member, and the annulus can provide a flow path between the hole and the screen portion. | 09-03-2009 |
| 20100059223 | SHROUDED TUBULAR - Disclosed herein is a shrouded tubular device that includes but is not limited to a tubular member, such as a screen joint; a shroud surrounding at least a portion of the tubular, the shroud is at least a two-piece shroud; and a shim in the annulus between the tubular member and the shroud. By way of example only, the shroud may be located directly radially inward from the joint of two of the shroud pieces. Also disclosed herein is a method for making a shrouded tubular device. | 03-11-2010 |
| 20100059232 | SYSTEM AND METHOD FOR RETAINING AN ELEMENT - The instant patent application discloses, among other things, a sand management system comprising an upper sand management portion and a lower sand management portion and an extendable leak-off tube. When the leak-off tube is in a fully retracted position, the leak-off tube is securely releasably engaged with upper sand management portion and when the leak-off tube is in a fully extended position, it is securely releasably engaged with the lower sand management portion. | 03-11-2010 |

| 20080289815 | DOWNHOLE SCREEN ASSEMBLY - A screen assembly that is used with a well includes a base pipe, a screen and ribs. The base pipe has a non-perforated section and has a longitudinal axis. The screen at least partially circumscribes the non-perforated section of the base pipe, and the ribs extend longitudinally in an annular space between the screen and the non-perforated section. A flexible member (e.g., a wire) is wrapped around the ribs. Various other mechanisms may be used instead of the ribs and flexible member in the annular space. In this regard, such annular standoffs such as a corrugated material, a member that has longitudinal channels, and a member formed from a first set of wires that is interwoven with a second set of wires may be used. Alternatively, longitudinal channels may be formed in the outer surface of the base pipe. | 11-27-2008 |
| 20090078403 | WELL SCREEN - A screen assembly connected about a perforated base pipe includes a filter layer constructed of layers of woven metal cloth sintered together; a drainage layer positioned between the base pipe and the filter layer, the drainage layer sintered to the filter layer; and a support layer constructed of woven metal rods and metal cable disposed about the filter layer, the support layer sintered to the filter layer. | 03-26-2009 |

| 20080314588 | SYSTEM AND METHOD FOR CONTROLLING EROSION OF COMPONENTS DURING WELL TREATMENT - A technique is provided for use in treating one or more well zones by directing a treatment fluid downwardly through a delivery tube and then outwardly through one or more nozzles into a desired well zone. The treatment fluid is delivered downhole to the desired well zone and at least a portion of that fluid is directed laterally outward from the well treatment completion through the one or more nozzles. Each nozzle comprises a material that protects both the nozzle and proximate portions of the delivery tube from detrimental erosion due to the passage of treatment fluid. | 12-25-2008 |
