    • Recovery of hydrocarbons, such as petroleum products, from a liquid or solid substrate is facilitated by the use of microwave energy to energize and separate molecular bonds between the hydrocarbons and the substrate. A radio frequency (RF) applicator delivers microwave energy to a treatment volume containing an emulsion of a hydrocarbon and a substrate. Delivering the microwave energy to the emulsion facilitates separation of the hydrocarbon and substrate molecules into layers. Hydrocarbons and other products can then be recovered from their respective layers. The treatment volume may be located either above or below ground. The RF applicator may include an antenna body with slots formed substantially parallel to one another in a substantially horizontal orientation. The RF applicator efficiently delivers microwave energy into the treatment volume. Substantially all of the power supplied to the RF applicator is radiated, with very little power reflected internally within the RF applicator.
    • 通过使用微波能量来激发和分离烃和基底之间的分子键,促进从液体或固体基质中回收烃类如石油产品。 射频(RF)施加器将微波能量传递到含有烃和基底的乳液的处理体积。 将微波能量提供给乳液有助于将烃和底物分子分离成层。 然后可以从各自的层回收碳氢化合物和其他产物。 治疗体积可以位于地面上方或下方。 RF施加器可以包括天线体,其具有基本上水平的方向基本上彼此平行的槽形成。 RF施加器有效地将微波能量传递到处理体积中。 基本上所有供给到RF施加器的功率被辐射,其中在RF施加器内部反射的功率非常小。

    • One embodiment of the present invention provides a method of treating a subterranean formation comprising introducing to a portion of a subterranean formation a slurry comprising a solid, particulate chelating agent substantially coated with a degradable material and a viscosified treatment fluid comprising a crosslinked gelling agent, allowing the degradable material to degrade and release the chelating agent into the viscosified treatment fluid; and, allowing the released chelating agent to delink at least a portion of the crosslinked gelling agent. Another embodiment provides a delinker for use in a viscosified treatment fluid comprising a crosslinked gelling agent, comprising a particulate chelating agent substantially coated with a degradable material wherein the degradable material is capable of degrading to release the chelating agent and wherein the released chelating agent is then capable of delinking at least a portion of the crosslinked gelling agent.
