A method of cleaning walls of a wellbore that includes contacting the walls with a cleaning fluid, the cleaning fluid comprising: a base fluid comprising a blend of a base oil and at least one of a mutual solvent or a terpene; and an alkyl glycoside is disclosed herein.

Cleaning agents for wellbore cleaning and methods of use thereof

A method of recovering formate from halide-contaminated formate brine that includes mixing a formate recovery solvent and the halide-contaminated formate brine; separating halide contaminants from the formate; and recovering the formate from the formate recovery solvent is disclosed.

Reclamation of halide-contaminated formate brines

A packer or annular fluid includes a hydrocarbon fluid; and a gelling agent; wherein the packer fluid is a yield power law fluid. A method for preparing a packer fluid includes preparing a mixture of a hydrocarbon fluid, and a gelling agent; heating the mixture to a selected temperature; and shearing the mixture. A method for emplacing a packer fluid into an annulus includes preparing the packer fluid that includes a hydrocarbon fluid and a gelling agent, wherein the packer fluid is a yield power law fluid; and pumping the packer fluid into the annulus.

Oil-based insulating packer fluid

A method for reclamation of a brine that includes mixing a brine containing thiocyanates with an oxidizing agent; and allowing for a time sufficient for the oxidizing agent to oxidize at least a portion of the thiocyanates is disclosed. Other methods may also include determining the quantity of unoxidized thiocyanates after the oxidizing treatment.

Using oxidizing agents to remove thiocyanates from brines

Compositions for increasing the thermal and pressure stability of well fluids viscosified using viscoelastic surfactants, the compositions including an effective amount of an oligomeric or polymeric compound that has a thermally stable backbone structure and at least one pendent viscoelastic surfactant functional group. Preferred compositions for increasing the stability of well fluids viscosified using monomeric viscoelastic surfactants include an effective amount of an oligomeric or polymeric compound that has a thermally stable backbone structure and a multiplicity of pendent viscoelastic surfactant functional groups attached to said backbone structure through relatively long hydrocarbon chains, 1 to 18 carbons in length.

Surfactant-polymer compositions for enhancing the stability of viscoelastic-surfactant based fluid

A monovalent cation containing well fluid composed of an aqueous brine containing at least 0.6 equivalents per liter of a water soluble monovalent cation salt, is substantially free of divalent cations, and an amount of a starch derivative selected such that the well fluid has the following characteristics: (a) a low shear rate viscosity greater than about 5,000 centipoise; (b) a high shear rate viscosity at 511 secin the range from about 15 to about 70 centipoise measured at 120&#xb0; F. is described. The fluid may be formulated to be substantially free of xanthan gums and preferably has less than 0.25 lb/bbl of xanthan gum.
