    Abstract: Oil based drilling fluids (muds) that include clays can be broken into at least three layers of their respective components (oil, water, and clay) by adding a few weight percent of a high HLB surfactant prediluted in water. Centrifugation can accelerate this separation process. The resulting oil, water, and clay layers can thereafter be more cost effectively recycled or disposed of following the process. In another embodiment an additional surface active agent is added to facilitate breaking the drilling mud into three or more phases without the centrifuge.

    Abstract translation: 包括粘土在内的油基钻井液（泥浆）可以通过加入少量重量百分比的预先稀释在水中的高HLB表面活性剂，将其分成至少三层各自的组分（油，水和粘土）。 离心可加速分离过程。 此后，所得到的油，水和粘土层可以在该方法之后更经济地回收或处理。 在另一个实施方案中，添加附加的表面活性剂以便于在没有离心机的情况下将钻井泥浆破碎成三个或更多个阶段。

    Abstract: A lubricant comprising (a) an oil of lubricating viscosity; (b) a polyether of number average molecular weight 1000 to 10,000; said polyether comprising alkylene oxide monomer units, where the alkylene group contains 3 to 6 carbon atoms, and ethylene oxide monomer units; and (c) one or more anti-foam agents, where the lubricant has a sulfated ash content of less than about 0.7 percent, is useful for lubricating a stationary gas engine where the engine drives a compressor and where both the engine and the compressor are lubricated with the same lubricant.
