摘要： Methods for reducing wear in pumping components during fracturing operations. A coated proppant is used that causes less wear on the pumping components as the proppant is pumped into the wellbore. The proppant coating consists of a substrate having a coating thereupon which eliminates sharp edges on the substrate and functions as a lubricant to materially reduce mechanical erosion of the pumping components. The proppant substrate may consist of any of a number of materials, including sand, ceramic, resin coated sand, or resin coated ceramic particle. The coating preferably comprises one or more layers of one or more of the following materials (or the coating having low friction coefficients is part of a mixture of the coating): antimony trioxide, bismuth, boric acid, calcium barium fluoride, copper, graphite, indium, fluoropolymers (FTFE), lead oxide, lead sulfide, molybdenum disulfide, niobium diselenide, polytetraf luoroethylene, silver, tin, or tungsten disulfideor zinc oxide. The coating material may be applied to the substrate in a number of ways known in the art.

摘要： A screen assembly for downhole uses features screen sections that have a valve associated with the screen base pipe. Flow through the screen has to go into an annular space to reach one or more ports on the base pipe over which is located a sliding sleeve. The sliding sleeve is preferably located at an axially spaced location from the screen and its underlying base pipe to allow the presence of the sliding sleeve to be located in a recess avoiding a drift diameter reduction in the screen assembly.

摘要： A fracturing and gravel packing tool has features that prevent well swabbing when the tool is picked up with respect to a set isolation packer. An upper or jet valve allows switching between the squeeze and circulation positions without risk of closing the wash pipe valve. The wash pipe valve can only be closed with multiple movements in opposed direction that occur after a predetermined force is held for a finite time to allow movement that arms the wash pipe valve. The jet valve can prevent fluid loss to the formation when being set down whether the crossover tool is supported on the packer or on the smart collet.

摘要： A device and system for controlling fluid flow into a wellbore tubular may include a flow path in a production control device and at least one in-flow control element along the flow path. A media in the in-flow control element adjusts a cross-sectional flow area of the flow path by interacting with water. The media may be an inorganic solid, a water swellable polymer, or ion exchange resin beads. A method for controlling a fluid flow into a wellbore tubular may include conveying the fluid via a flow path from the formation into a flow bore of the wellbore; and adjusting a cross-sectional flow area of at least a portion of the flow path using a media that interacts with water. The method may include calibrating the media to permit a predetermined amount of flow across the media after interacts with water.

摘要： In one aspect of the invention a valve that operates in association with a downhole screen is threaded into the wall of a base pipe after being inserted through a saddle. When the valve body is threaded in, the engagement into the wall threads in the base pipe acts as a sealing force on a ring seal between the saddle and the base pipe and between the valve body and the saddle. The valve itself can be outfitted with a cover with openings that can be integral or removable and disposed at the end of the valve that is innermost to the base pipe. Preferably a series of elongated slots are used that can catch slurry if the well is to be killed while allowing subsequent production to drive the accumulated solids from well killing back into the base pipe. Another feature places the valve in a base pipe opening under a cylindrical screen section to reduce assembly time and cost of constructing an adjacent housing to one side of the cylindrical screen section to accommodate the valve.
摘要翻译：在本发明的一个方面中，与井下筛相关联地操作的阀在插入鞍座之后被拧入基管的壁中。当阀体穿入时，与基管中的壁螺纹的接合充当对鞍座和基管之间以及阀体和鞍座之间的密封环的密封力。阀门本身可以配备一个带有开口的盖子，这些开口可以是一体的或可拆卸的，并且设置在阀门的最底端到基管的末端。优选使用一系列细长的狭槽，如果井要被杀死，则可捕获泥浆，同时允许随后的生产将积聚的固体从井中驱赶回到基管中。另一个特点是将阀门放置在圆柱形筛管部分下方的基管开口中，以减少将相邻的外壳构造到圆柱形筛管部分的一侧以容纳阀门的组装时间和成本。
