| 20080283252 | SYSTEM AND METHOD FOR MULTI-ZONE WELL TREATMENT - A technique is provided for treating a plurality of well zones with a service tool during a single trip downhole. The service tool is run downhole to a selected well zone that is isolated for treatment. Following treatment of the well zone, the service tool is moved to a subsequent well zone isolated for treatment. When the lengths of the well zones to be treated are dissimilar, the active length of the service tool can be adjusted to correspond with the well zone length to optimize the well treatment operation. | 11-20-2008 |
| 20080314589 | SYSTEM AND METHOD FOR CREATING A GRAVEL PACK - A technique is provided for forming a gravel pack at a well zone. A completion assembly is positioned in a wellbore and cooperates with a service tool engaging the completion assembly. The completion assembly comprises a completion assembly central bore. A return is located radially outward of the central bore at a specific well zone or zones and comprises a flow path for returning a carrier fluid. The location of the return allows flow of the returning carrier fluid to remain outside of the completion assembly central bore at a specific well zone or zones. | 12-25-2008 |
| 20090078421 | SYSTEM AND METHOD FOR PERFORMING WELL TREATMENTS - A technique is provided for performing a well treatment operation. A completion assembly is constructed with a tubular member designed to maintain pressure integrity above a given well treatment zone. The completion assembly and a service tool can be moved downhole for well treatment operations in one or more well zones. A converter tool is utilized to selectively form openings through a wall of the tubular member to enable flow following completion of the well treatment in a lower zone. | 03-26-2009 |
| 20090095471 | MULTI-ZONE GRAVEL PACK SYSTEM WITH PIPE COUPLING AND INTEGRATED VALVE - Apparatus having a first outer tubular member and a first inner tubular member. The first outer tubular member and the first inner tubular member can define a first space therebetween. The first inner tubular member can have a first internal bore. The apparatus can further include a second outer tubular member and a second inner tubular member. The second outer tubular member and the second inner tubular member can define a second space therebetween. The second inner tubular member can have a second internal bore. A first coupling flowpath can be positioned between the first and second spaces. A second coupling flowpath can be positioned between the first and second internal bores. A selectively closeable flowpath can be positioned between the first coupling flowpath and the second coupling flowpath. | 04-16-2009 |
| 20090188674 | SYSTEM AND METHOD FOR PREVENTING BUCKLING DURING A GRAVEL PACKING OPERATION - A technique is provided for preventing buckling of a service tool assembly during a sand control operation in a wellbore. A completion assembly and a service tool assembly are positioned in a wellbore. An anti-buckling mechanism is positioned to limit the buckling load effects that can otherwise be experienced by the service tool assembly during the sand control operation. | 07-30-2009 |

| 20080317100 | Method and Device for Blind Dehopping - A method and device are disclosed for real-time characterization of frequency-hopping networks, in which the signal to be characterized is converted into a digital signal and the frequency characteristics of the signal are determined. A frequency hop is sought for synchronization with the start of the transmission. The frequency is tracked and the central frequency Fc of the required transmission channel is sought. A delay is applied to the digitized samples during the tracking phase. The samples corresponding to the signal step are determined on the basis of the delayed samples and the identified central frequency. | 12-25-2008 |
