    Abstract: A treated cellulosic material comprising a cellulosic material having a porous structure defining a plurality of pores, at least a portion of the pores containing a treating agent comprising a polymer comprising a modified cellulose polymer; and a modifying agent comprising a hydrophobic amine, a metal ion, or a quat. The present disclosure further describes a method for preparing a treated cellulosic material comprising (a) providing a cellulosic material; (b) a first treatment protocol comprising impregnating the cellulosic material with a dispersion comprising a polymer, the polymer comprising a modified cellulose polymer; and (c) a second treatment protocol comprising impregnating the cellulosic material with a modifying agent, the modifying agent comprising a hydrophobic amine, a metal ion, or a quat.

    Abstract: The hydration of clays and shale in drilling operations may be inhibited by employing an aqueous based drilling fluid comprising a shale hydration inhibition agent having the formula: (Formula I should be inserted here.) wherein R is hydrogen or an alkyl group having 1 to 12 carbons, R1 is an alkylene group having 1 to 12 carbons, and R2 is an alkyl group having 1 to 12 carbons. The shale hydration inhibition agent should be present in the aqueous based drilling fluid in sufficient concentration to reduce the reactivity, such as swelling, of clays and shale when exposed to water-based drilling fluids.

    Abstract translation: 通过采用包含具有下式的页岩水化抑制剂的含水基钻井液可以抑制钻井作业中粘土和页岩的水合作用（式Ⅰ应在此插入），其中R是氢或1至12的烷基 碳，R1为碳数为1〜12的亚烷基，R2为碳数为1〜12的烷基。 页岩水化抑制剂应以足够的浓度存在于含水基钻井液中，以降低暴露于水基钻井液时粘土和页岩的反应性，例如膨胀。
