摘要： Catalyst particles and methods for making same are disclosed herein. The catalyst particles can include a ceramic support containing silica and alumina. The ceramic support can have a macropore concentration of about 15% to about 45%, a mesopore concentration of about 20% to 50%, and a micropore concentration of about 8% to about 30% based on the total pore volume of the ceramic support. The ceramic support can also have a surface area of about 0.5 m2/g to about 50 m2/g.

摘要： Switchable crossover tools can include a tool body and a rotatable chamber. The tool body includes a main tool path separable into uphole and downhole tool paths and an auxiliary chamber containing uphole and downhole annular ports. The rotatable chamber is located and rotatable within the auxiliary chamber and forming first and second auxiliary flow paths through the auxiliary chamber. The rotatable chamber is positionable between a conventional circulation mode and a reverse circulation mode. In the conventional circulation mode, the uphole and downhole tool paths are in fluid communication and the uphole and downhole annular ports are in fluid communication through the auxiliary chamber. In the reverse circulation mode, the uphole tool path is in fluid communication with the downhole annular port via the first auxiliary flow path, and the downhole tool path is in fluid communication with the uphole annular port via the second auxiliary flow path.

摘要： A well tool assembly can include a well screen configured to filter fluid flow between an interior and an exterior of a tubular string, and an outflow control section that permits the fluid flow in an outward direction and prevents the fluid flow in an inward direction, the outflow control section including at least two outflow control valves arranged in series. A method can include installing a well tool assembly including a well screen, flowing a fluid from an exterior to an interior of a tubular string through the well screen and an inflow control valve of the well tool assembly, and flowing another fluid from the interior to the exterior of the tubular string through the well screen and at least one outflow control valve of the well tool assembly.

摘要： A sand control screen for heavy oil thermal recovery, including: a core base pipe having a plurality of base-pipe holes distributed on a pipe body thereof; a filtering sleeve sleeved on the core base pipe and arranged with respect to the base pipe holes; and a non-welded support disk mounted on the core base pipe and fastening the filter sleeve to the core base pipe by means of a wedge insertion locking and sealing structure. The invention solves the problems in the prior art in which sand control screen has a poor reliability in a high-temperature condition of a thermal production well, resulting in potential safety risks of down hole sand control operation of the screens. In addition, the sand control screen of the present invention has a long service life, thus improving cost effectiveness of oil wells.

摘要： Remotely actuated screenout relief valves, systems and methods are disclosed herein. The methods include providing a proppant slurry stream that includes proppant to a casing conduit that is defined by a casing string that extends within a subterranean formation. The methods further include detecting an operational parameter that is indicative of a screenout event within the casing conduit. Responsive to the detecting, the methods include providing a flush fluid stream to the casing conduit, opening the remotely actuated screenout relief valve, and displacing the proppant from the casing conduit into the subterranean formation with the flush fluid stream via the remotely actuated screenout relief valve. The methods may further include closing the remotely actuated screenout relief valve. The systems include hydrocarbon wells that include the remotely actuated screenout relief valve and/or hydrocarbon wells that include controllers that are configured to perform at least a portion of the methods.

摘要： An apparatus and method according to which a zone of a wellbore that traverses a subterranean formation is completed. The apparatus includes a flow joint including a first internal flow passage, and a plurality of openings formed radially therethrough, a plurality of plugs disposed within the plurality of openings to form a fluid and pressure tight seal with the flow joint, thus impeding fluid flow through the plurality of openings, and a screen disposed exteriorly about the flow joint and axially along the plurality of openings, and thus also along the plurality of plugs, wherein, when the plurality of plugs are exposed to a downhole fluid, the plurality of plugs are adapted to degrade so that fluid flow is permitted through the plurality of openings. The plurality of plugs may include protective layers adapted to be damaged or removed to expose the plurality of plugs to the downhole fluid.

摘要： Methods and compositions using surface chemistry and internal porosity of proppant particulates to consolidate the proppant particulates are described herein. The methods can include a method of gravel packing a wellbore. The method can include mixing an activator, a thickener, a crosslinker and a plurality of resin-coated proppant particulates to provide a gravel pack fluid and introducing the gravel pack fluid into a gravel pack region of the wellbore. The method can also include consolidating at least a portion of the plurality of resin-coated proppant particulates to provide a consolidated gravel pack, wherein the consolidated gravel pack has a UCS of at least about 60 psi when formed under a pressure of about 0.01 psi to about 50 psi and a temperature of about 160° F. to about 250° F.
