摘要： Systems and methods for fracturing multiple zones in a wellbore are provided. A first port in a first valve assembly can be opened with a shifting tool. A fluid flows through the first port to fracture a first zone, and the first port can be closed with the shifting tool after the first zone has been fractured. A second port can be opened in a second valve assembly with the shifting tool after the first port has been closed, wherein the second valve assembly is positioned below the first valve assembly. The fluid can flow through the second port to fracture a second zone, and the second port can be closed with the shifting tool after the second zone has been fractured.

摘要： Steerable drilling systems for facilitating drilling according to a prescribed, three-dimensional trajectory are described. Steering may be achieved using passive actuators which require little or no power. For example, damping elements which couple a drill bit to a drill collar can be used to tilt the drill bit with respect to the drill collar. Alternatively, rotary cutting elements disposed on the drill bit may be used to control the force between the drill bit and the formation at different axial locations. The passive elements used to control the tilt or rotation of the rotary cutting elements are actuated in a certain pattern, e.g., geostationary, in order to achieve a desired deviation of the well bore while drilling ahead. One way to achieve this is through the use of field-sensitive materials, e.g. magnetorheological (MR) fluids, that change viscosity in response to an applied magnetic field.
摘要翻译：描述了根据规定的三维轨迹促进钻孔的可操纵钻孔系统。可以使用需要很少或没有动力的被动致动器来实现转向。例如，将钻头耦合到钻铤的阻尼元件可用于相对于钻铤倾斜钻头。或者，设置在钻头上的旋转切割元件可以用于在不同的轴向位置处控制钻头和地层之间的力。用于控制旋转切割元件的倾斜或旋转的被动元件以某种图案（例如，对地静止的）被致动，以便在向前钻孔时实现井眼的期望偏差。实现这一点的一种方法是通过使用场敏感材料，例如磁流变（MR）流体，其响应于施加的磁场而改变粘度。

摘要： A sol of metallic alkoxide is pumped into a desired location in a wellbore and allowed to gel, creating solids in-situ. The sol is either unstabilized, requiring rapid placement before gelling, or the sol is stabilized, permitting off-site mixing. Sols can be stabilized with either surfactant or with interfacial polymers. Large concentrations of surfactant can be placed in the sol to create templates around which gelation occurs, creating porous solids.

摘要： An abrasion resistant coating and method are provided wherein the abrasion resistant coating contains both ductile and brittle components having a bimodal size distribution. The abrasion resistant coating is initially applied to a substrate in contact with an abrasive environment. The abrasive resistant coating having a bimodal size distribution results in the minimized exposure of the ductile components of the wear surface to the abrasive environment such that the life of the abrasive resistant coating is extended.

摘要： Swellable compositions and methods of using and controlling them are disclosed. In certain examples, the swellable composition may comprise an active phase responsive to swell upon exposure to a swelling fluid. In some examples, the active phase of the swellable composition is effective to deswell in response to an applied stimulus in the presence of the swelling fluid. In other examples, the swellable composition may further comprise a passive phase responsive to swell to a lesser degree than the active phase upon exposure to the swelling fluid. Devices and systems using the swellable compositions are also described.
