    摘要: A polymer nanocomposite comprises a polymer; and a nanoparticle derivatized to include functional groups including carboxy, epoxy, ether, ketone, amine, hydroxy, alkoxy, alkyl, aryl, aralkyl, alkaryl, lactone, functionalized polymeric or oligomeric groups, or a combination comprising at least one of the forgoing functional groups. The variability in tensile strength and percent elongation for the polymer nanocomposite is less than the variability of these properties obtained where an underivatized nanoparticle is included in place of the derivatized nanoparticle.

    摘要: A fracturing method for preferably open hole uses fluid velocity impinging on the wellbore wall to initiate fractures. Telescoping members that extend using nozzles inside them but come out to a distance from the wellbore wall can be used. Fixed nozzles that do not extend are also another option. The nozzles can be eroded or corroded as the fracturing takes place or they can be made of sufficiently durable materials or have coatings to withstand the erosive effects of high velocity slurries pumped to impinge the wellbore wall to initiate fractures.

    摘要: A tubular centralizer is secured to the tubular for run in. The profile for run in is small so that damage to the centralizer is minimized during run in. When the string is in position the centralizer is actuated to change shape or volume to engage the surrounding borehole to centralize the tubular for subsequent operations such as cementing or in the case of screens for gravel packing. The centralizer can be a shape memory material that is initially compressed at above its transition temperature to hold the smaller shape. At the desired location after run in it is brought above the transition temperature and changes back to the original shape or volume to centralize the tubular string. The structure can be spaced ring segments or a cohesive ring structure with an undulating profile or radiating blades to create flow spaces in the annulus where it is deployed for flow of a sealing material or gravel, for example.

    摘要: A flow control device may include a body having at least two flow paths configured to convey the fluid. The flow paths may be hydraulically isolated from one another in the body and at least one of the flow paths may be selectively occludable. In certain arrangements, a filtration element may be positioned upstream of one or more of the plurality of in-flow control devices. The flow paths may utilize features such as chamber and openings in order to impose a specified pressure drop on the fluid flowing thereacross.
