20100032151 | Convertible downhole devices - A convertible downhole device comprises at least one sacrificial material to provide two or more configurations so that two or more different operations or functions are performable by the downhole device, one in which the sacrificial material is fully intact and another in which the sacrificial material is at least partially removed or disappeared. The sacrificial material may be removable through any suitable method or device, such as by contacting with a fluid, by temperature, by pressure, or by combustion, ignition, or activation of a fusible or energetic material, or crushing or breaking up of a frangible material. Upon removal of the sacrificial material, the downhole device has at least one additional configuration so that at least a second operation can be performed by the downhole device. | 02-11-2010 |

Upon removal of the sacrificial material, the downhole device has at least one additional configuration so that at least a second operation can be performed by the downhole device. | 10-07-2010 |
20110030975 | TUBULAR SYSTEM WITH SELECTIVELY ENGAGABLE SLEEVES AND METHOD - A tubular system with selectively engagable sleeves includes, a tubular, a plurality of sleeves disposed at the tubular, and a plurality of engagable members being movable through the tubular with each of the plurality of engagable members being configurable to selectively engage with at least one of the plurality of sleeves and such engagement at least temporarily preventing passage of an engaged engagable member by an engaged sleeve. | 02-10-2011 |
20110067882 | System and Method for Monitoring and Controlling Wellbore Parameters - In one aspect, a method is provided for producing fluid from a well formed in a formation including the step of generating a visual display depicting a depth-based layout of a plurality of production devices, a first setting of each production device and values for at least one production parameter, wherein the visual display enables an operator to graphically input a desired value for the at least one production parameter at a selected depth of the well. The method also includes determining a second setting for at least one production device utilizing a model and the desired value, wherein the second setting is expected to provide the desired value for the at least one production parameter the second setting is implemented. | 03-24-2011 |
20110073321 | TUBULAR ACTUATOR AND METHOD - A tubular actuator includes, a tubular, a support member disposed at the tubular, and a restrictor configured to pass a runnable member when unsupported by the support member and to prevent passage of the runnable member when supported by the support member. The restrictor is movable relative to the support member from an unsupported position to a supported position in response to pressure applied against the runnable member engaged with the restrictor according to a pressure versus time profile. | 03-31-2011 |
20110226481 | Apparatus and Method for Controlling Fluid Flow Between Formations and Wellbores - In one aspect, a passive flow control device for controlling flow of a fluid is provided, which device in one configuration include a longitudinal member configured to receive fluid radially along a selected length of the longitudinal member, the longitudinal member including flow restrictions configured to cause a pressure drop across the radial direction of the longitudinal member. In another aspect, a method of completing a wellbore is provided, which method in one embodiment may include providing a flow control device that includes a tubular with a first set of fluid flow passages and at least one member with a second set of fluid passages placed outside the tubular, wherein the first and second set of passages are offset along a longitudinal direction and the member is configured to receive a fluid along the radial direction; placing the flow control device at a selected location a wellbore; and allowing a fluid flow between the formation and the flow control device. | 09-22-2011 |
20110265941 | On Site Manufactured Self Expanding Tubulars and Method - Tubular is manufactured at a well site to a predetermined size using flat stock that is rolled into a c-shape from a plurality of feed locations. The c-shapes have open segments that are offset from each other to form the tubular shape. A binder material such as a reactive nano-foil is applied on assembly as the tubular shape is formed. The manufactured shape is reduced to a smaller dimension for run in. The cross-sectional reduced profile shape can be a smaller diameter or a crescent or an undulating shape that is triggered to revert to the original manufactured shape and size when placed downhole. The manufacturing method is capable of making continuous pipe for the length of the zone without connections. The bonding of the segments is preferably done at the time of fabrication at the well site but can also occur at least in part downhole. | 11-03-2011 |
