  • Method of using low-density, freezable fluid to create a flow barrier in a well
    Patent number: 10202733
    Abstract: Disclosed herein is a temporary wellbore sealant, comprising water, a gelling agent; and a filler, wherein: the filler has a lower specific gravity than the water of the sealant; and the sealant has a lower specific heat than the water of the sealant and a method of temporarily sealing a liquid filled wellbore therewith.
    Type: Grant

  • Cementing composition comprising nonionic hydrophobically-modified cellulose ethers and its use
    Patent number: 9416051
    Abstract: Disclosed is a composition and a method for cementing a casing in a borehole of a well using an aqueous cementing composition comprising (a) water, (b) a cementing composition comprising (i) a hydraulic cement, (ii) a hydrophobically modified polymer, (iii) a dispersant, and optionally (iv) one or more other additives conventionally added to aqueous cementing compositions useful in cementing casings in the borehole of wells. Preferably the hydrophobically modified hydroxyethyl cellulose has an ethylene oxide molar substitution of from 0.5 to 3.5, a hydrophobe degree of substitution of from 0.001 to 0.025, and a weight-average molecular weight of from 500,000 to 4,000,000 Daltons and the dispersant is sulfonated polymer, melamine formaldehyde condensate, a naphthalene formaldehyde condensate, a branched or non-branched polycarboxylate polymer.
