  • Patent number: 11859123
    Abstract: A method comprising (a) contacting a suspension composition, water, and optionally one or more additives to form a wellbore servicing fluid at a location proximate a wellsite; wherein the suspension composition comprises a particulate material, an organic carrier fluid, and a suspension viscosifier; and (b) placing the wellbore servicing fluid in a wellbore penetrating a subterranean formation. The wellsite comprises an offshore platform, a floating vessel, or combinations thereof; and wherein the wellbore is offshore. A suspension composition comprising a particulate material, an organic carrier fluid, and a suspension viscosifier; wherein the particulate material is substantially insoluble in the organic carrier fluid; wherein the particulate material comprises a water-interactive material and/or a water-insoluble material; and wherein the organic carrier fluid comprises a glycol and/or a glycol ether.

  • Publication number: 20230257643
    Abstract: Disclosed herein is a surfactant package comprising a base oil, a mutual solvent, and a surfactant, wherein the surfactant is selected from the group consisting of alcohol ethoxylates, fatty alcohol ethoxylates, alkylphenol ethoxylates, nonoxynols, fatty acid esters of sorbitol, alkyl ether carboxylic acids, ethoxysulfates, and combinations thereof. Also disclosed herein is a wellbore servicing fluid comprising an aqueous fluid and the surfactant package. The wellbore servicing fluid can be used in a method of servicing a wellbore penetrating a subterranean formation. The wellbore servicing fluid has an increased mud removal percentage, is compatible with an OBM and a cementitious fluid, and has reduced environmental impacts. The surfactant package can be added into the wellbore servicing fluid as a single component, which can save storage space and preparation time of the wellbore servicing fluid, thus the surfactant package can be used at a location having limited equipment/tools/space (e.g.
