    摘要： A method of preparing and using a subterranean formation stabilization agent. The stabilization agent includes a guanidyl copolymer and may be admixed with a fracturing fluid and optionally brine. The stabilization agent is effective in preventing and/or reducing, for example, clay swelling and fines migration from a subterranean formation contacted with the stabilization agent.

    摘要： A dual bladed surgical saw and method of use. Two blade assemblies are attached to a saw body. Each blade assembly includes an oscillator driving a blade, and teeth on each blade. The blades are disposed at a pre-determined blade angle relative to each other, thus allowing two cuts to be made simultaneously and independently at the blade angle relative to each other. The blade assemblies may be rotatable relative to each other, which allows the pre-set blade angle to be varied appropriate to the procedure contemplated. One embodiment uses a slotted protractor bearing protractor indicia, and a threaded fastener to set the blade angle. Another embodiment uses shims between blade assembly arms to quickly and accurately set the blade angle. Method steps include pre-setting the blade angle, and making two cuts simultaneously at an angle relative to each other equal to the blade angle.

    摘要翻译： 双刀片外科手术刀及其使用方法。 两个叶片组件连接到锯体上。 每个叶片组件包括驱动叶片的振荡器和每个叶片上的齿。 叶片相对于彼此以预定的叶片角度设置，从而允许两个切口以相对于彼此的叶片角度同时且独立地进行。 叶片组件可以相对于彼此旋转，这允许预设叶片角度适合于所设想的程序。 一个实施例使用带槽的量角器轴承量角器标记和螺纹紧固件来设定叶片角度。 另一实施例使用叶片组合臂之间的垫片快速且准确地设定叶片角度。 方法步骤包括预设叶片角度，并且以相对于叶片角度相对于彼此成一定角度同时进行两个切割。
