Disclosed are treatments of recovered commercial solids and use of the treated recovered commercial solids in well treatment fluids. Systems and methods are disclosed for chemically treating recovered commercial solids to remove contaminants and then recycling the recovered commercial solids by using them in a treatment fluid.

Treatment of recovered commercial solids for use in oilfield fluids

Diesel oil-based invert emulsion drilling fluids having fragile gel properties and improved performance. Methods are also disclosed for drilling, running casing, cementing, and/or producing hydrocarbons in a subterranean formation.

Diesel oil-based invert emulsion drilling fluids and methods of drilling boreholes

A method of reducing the viscosity of invert emulsions and oil-based drilling fluids and well service fluids comprising such emulsions over a broad temperature range is disclosed. The method comprises adding to said invert emulsions of the invention a non-ionic surfactant alone or in combination with a co-thinner having the formula: R&#x2033;&#x2033;&#x2014;(CHO)(CHO)(CHO)&#x2014;H where R&#x2033;&#x2033; is a saturated or unsaturated, linear or branched, alkyl radical having about 8 to about 24 carbon atoms, n is a number ranging from about 1 to about 10, m is a number ranging from about 0 to about 10, and k is a number ranging from about 0 to about 10. The non-ionic surfactant is a reaction product of ethylene oxide, propylene oxide and/or butylene oxide with Ccarboxylic acids or Ccarboxylic acid derivatives containing at least in position 9/10 and/or 13/14 structural units of general formula (I) where Ris a hydrogen atom or an OH group or a group OR. Ris an alkyl group of about 1 to about 18 carbon atoms, an alkenyl group of about 2 to about 18 carbons atoms, or a group of the formula (II): Ris a hydrogen atom, an alkyl group of about 1 to about 21 carbon atoms or an alkylene group or 2 to 21 carbon atoms. 

Thinners for invert emulsions

A method of reducing the viscosity of oil-based drilling fluids and well service fluids at low temperatures and a thinner compound for use in such drilling fluids and well service fluids is disclosed. The method comprises adding to said drilling fluids or well service fluids a thinner having the formula:R&#x2014;(CHO)(CHO)(CHO)-Hwhere R is a saturated or unsaturated, linear or branched alkyl radical having about 8 to about 24 carbon atoms, n is a number ranging from about 1 to about 10, m is a number ranging form about 0 to about 10, and k is a number ranging from about 0 to about 10.
