    • The present disclosure provides a bulk treatment for introduction into a hydrocarbon bearing formation, the bulk treatment comprising a volume of a treatment fluid comprising chlorine dioxide, wherein the volume is such that when the treatment fluid is introduced into a wellbore that penetrates the hydrocarbon bearing formation, the fluid is expected to extend into the formation to a radius that goes beyond the near wellbore region. Such a bulk treatment can act to draw out hydrocarbons from a hydrocarbon-bearing formation, thereby enhancing recovery of oil and/or gas. Also provided herein are mixtures comprising chlorine dioxide, water, an organic non-polar solvent, and optionally one or more additional components (e.g., an acid or chelating agent and/or a surfactant or cosolvent). The mixtures are useful for enhancing recovery of oil and/or gas and for removing residues that contain hydrocarbons. Apparatus for making the mixtures, and methods of making and using the mixtures, e.g., to mitigate damage and/or enhance recovery of oil and/or gas from a petroleum well, are also disclosed.
    • 本发明提供了用于引入到含烃地层中的整体处理,所述整体处理包括一定体积的包含二氧化氯的处理流体,其中所述体积使得当处理流体被引入到 穿过含烃地层的井筒,预计流体会延伸到地层中,超出近井筒区域的半径。 这样的整体处理可用于从含烃地层抽出烃,从而提高油和/或气的回收率。 本文还提供了包含二氧化氯,水,有机非极性溶剂和任选的一种或多种另外的组分(例如酸或螯合剂和/或表面活性剂或共溶剂)的混合物。 该混合物可用于提高油和/或气体的回收率并用于去除含烃的残余物。 还公开了用于制造混合物的设备以及制造和使用混合物的方法,例如以减轻损害和/或增强从石油井的油和/或气体的回收。
