| 20100071908 | DOWNHOLE BACKUP SYSTEM AND METHOD - A downhole backup system including, a tubular positionable within a downhole structure such that an annular space exists between the tubular and the downhole structure, and a plurality of wedges that are radially movably positioned within the annular space, each of two opposing ends of the plurality of wedges are configured to completely cover the annular space at all possible radial positions of the plurality of wedges. | 03-25-2010 |
| 20110036561 | Retractable Downhole Backup Assembly for Circumferential Seal Support - Wedge shaped elements form a ring structure that can increase in diameter for a grip using relative axial motion of adjacent segments. The adjacent seal is further separated from access to the edges of the adjacent segments that move relatively by ring segments attached to the wide dimension of the segments that face the seal. The ring segments move out with the wedge elements to which they are attached so that in the set position of the seal there is an enhanced barrier against the surrounding tubular with the ring segments. The ring segments further block access of the seal under compressive loading to the interface locations between the wedge shaped elements so that their relative axial movement does not trap a portion of the seal and initiate cracks in the seal that can lead to leakage past the seal. | 02-17-2011 |
| 20120037355 | Retractable Petal Collet Backup for a Subterranean Seal - A high expansion plug has multiple sealing elements and an extrusion barrier system that uses overlapping petals in a stack of rings. When setting the plug, the petals are elastically moved toward a surrounding tubular wall in an elastic deformation between a housing that surrounds the mandrel and a tapered ring on the mandrel. That sandwich controls the amount of deformation and allows a potential energy force to be stored in the petals that allows them to return toward their initial position when the set of the plug is released and the seals are allowed to relax and extend axially as they shrink radially. The plug can then be removed without milling. Expansions in the order of 25% of the initial seal dimension are contemplated. | 02-16-2012 |
| 20120043073 | Twin Latch Wireline Retrieval Tool - The retrieving tool engages an equalizing sleeve on a jar down movement while the packer or bridge plug release sleeve is held fixed with a locking dog. The initial jarring down allows the tool to engage the equalizing sleeve and pull it up subsequent to the initial engagement by jarring down. Pulling or jarring up then opens the equalizing ports while still holding the release sleeve locked using a trapped collet. A subsequent jarring down allows engagement of a second sleeve so that a subsequent pulling or jarring up moves the second sleeve away from the collet that had otherwise held the set position of the packer or bridge plug. A pull or jar force up brings up the now released packer or bridge plug. | 02-23-2012 |

| 20080243763 | SYSTEM, METHOD AND PROGRAM TO PROVIDE DATA TO ANOTHER PROGRAM - System, method and program product for providing data to a program for processing. An electronic spreadsheet is formed. One or more cells in the spreadsheet are mapped to the program. Based on the mapping, one or more data entries in the one or more cells, respectively are automatically forwarded to the program for processing. The data entries can be forwarded in data objects. Alternately, a list of data objects available for export are published. The data objects include respective data entries from respective cells in an electronic spreadsheet. In response to the program requesting one or more of the data objects, the one or more data objects are forwarded to the program for processing. | 10-02-2008 |
| 20080301807 | System and Method for Controlling On-Demand Security - An on-demand security service ensures isolation of the service provider's customers where the customers share resources at the system, subsystem, and storage level. The security service is provided in a pre-production phase and in a post production phase. The pre-production phase takes place prior to boarding the customer. In the pre-production phase the resources to be protected are defined in a security guide, and using the security guide, physical segregation at the facility, network, and technical and delivery support levels is planned and then implemented. In the post production phase, on going activities are proactive and reactive. Proactive activities include maintaining physical segregation by reviewing and updating the security guide, and testing physical segregation by performing security audits and penetration tests. Observations and finding of the audits and penetration tests are resolved. Reactive activities include identifying isolation failures, coordinating appropriate actions, and resolving the isolation failure. The service may be embodied in a system and in a computer implemented process comprising a security guide file (SGF), a security guide application (SGA), a security implementation application (SIA), a security validation application (SVA), and an event coordination application (ECA). | 12-04-2008 |
| 20090171741 | BSM Problem Analysis Programmable Apparatus - A system (apparatus), computer implemented method, and program product for analyzing a problem in a distributed processing business system used to provide a service comprises identifying the problem; preparing for an audit; performing the audit; reviewing the audit; developing an action plan; developing an execution plan; deploying a solution in accordance with the execution plan; monitoring the deployed solution; and recording lessons learned. Alternatively, the system (apparatus), computer implemented method, and program product may be applied to evaluate the capacity of a distributed processing business system to provide a prospective service. In this alternative embodiment, the system (apparatus), computer implemented method, and program product comprises identifying the problem; preparing for an audit; performing the audit; reviewing the audit; preparing a rating table; populating the rating table with results from the audit; calculating a service rating based upon the results entered in the rating table; and presenting the service rating to management. | 07-02-2009 |

| 20090010714 | LNG RECEIVING TERMINAL THAT PRIMARILY USES COMPENSATED SALT CAVERN STORAGE AND METHOD OF USE - In the past, “compensated” salt caverns have operated with a compensating liquid, such as brine to displace a stored liquid, such as crude oil, when the stored liquid is needed on the surface. Virtually all of the stored liquid in a compensated salt cavern can be expelled from the salt cavern when it is filled with the compensating liquid. In the past, “uncompensated” salt caverns have been used to store gases, such as natural gas. Uncompensated caverns operate without any compensating liquid; instead they rely on pressure. Some of the stored gas (cushion gas) must always be left in an uncompensated salt cavern. This invention breaks with convention and uses a compensating liquid in a salt cavern to store gases which is a technique believed to be previously unknown. “Cushion gas” is not required because the compensating liquid displaces virtually all of the gas in the salt cavern. | 01-08-2009 |
| 20090309408 | Method and system for solution mining - A relatively warm mineral deposit is solution mined by injecting fluid through a well drilled into the deposit and dissolving the mineral to form a production brine. Warm production brine is cooled at the surface using a heat exchanger as a crystallizer to precipitate the mineral in the exchanger and form a slurry. Crystals of the mineral in the slurry are recovered in a separation plant leaving a relatively cool, dilute or depleted brine, which is conveyed through the heat exchanger for cooling the production brine and then injected into the mineral deposit to dissolve more mineral thereby providing a continuous process. A pipe-in-pipe heat exchanger is preferably used and in a manner so that the heat exchanger also serves as a primary means for conveying the production fluid and/or slurry from the well to the separation plant. This method extracts and recovers the desired mineral(s), recovers much of the heat in the production brine, accelerates the solution mining process since the injection fluid has been warmed, reduces salting in the production string, is relatively inexpensive to install and maintain, and does not require a source of energy for cooling the production brine such as electricity for a refrigeration system. | 12-17-2009 |
