Solvent-based suspensions of asphaltite comprising a carrier fluid, an asphaltite powder and a suspending agent, wherein said suspending agent is a copolymer of a monoethylenically unsaturated monomer containing a carboxylic group and of a C-C(meth)acrylic acid alkyl ester; subterranean treatment fluid containing the solvent-based suspensions of asphaltite and method for treating a subterranean formation by use of the subterranean treatment fluid.

Solvent-based asphaltite suspensions

The present invention relates to a water-based subterranean treatment fluid, comprising: a) a continuous aqueous phase; b) an internal oil phase; c) from 0.1 to 15 g/100 ml, based on the total fluid volume, of an emulsifying composition comprising a first surfactant having a HLB from 10 to 20 and a second surfactant obtained by reacting a saturated or unsaturated aliphatic monocarboxylic acid, ethylene oxide and a hydroxyalkylamine. The invention further relates to a method for treating a subterranean formation comprising providing said water-based subterranean treatment fluid.

Emulsifiers for water-based subterranean treatment fluids

Disclosed herein are methods for treating hydrocarbon-bearing formations previously subjected to hydraulic fracturing, in which at least some of the methods include pumping into a wellbore a treatment composition comprising LPG combined with one or more surfactants each of which is fully or partially dissolved into the LPG, causing the treatment composition to make contact with water residing in the formation such that at least a portion of the one or more surfactants dissolves into the water, and recovering a composition that includes residual hydrocarbons and at least some of the LPG and water that resided in the formation and at least some of the one or more surfactants that were pumped into the wellbore.

Methods and systems for treating hydraulically fractured formations

The present invention relates to a method to inhibit gas hydrate formation in the field of crude oil and natural gas extraction, transportation and processing.

Gas hydrate inhibitors

The present invention relates to a hydrocarbon-free emulsion stabilizer, to water-in-oil subterranean treatment fluids comprising said stabilizer and having improved stability and environmental compatibility, and to their use in subterranean treatments.

Hydrocarbon-free emulsifier

Water-in-oil subterranean treatment fluids with improved stability and environmental compatibility comprise esteramides as emulsion stabilizer.

Esteramides and subterranean treatment fluids containing said esteramides

The present invention relates to hydrophobically modified hydroxyalkyl guar derivatives which dissolve rapidly in water, having a hydroxyalkyl molar substitution between 0.2 and 2.5 and containing hydrophobic groups comprising C10-C32 alkyl chains, to the procedure for their preparation and to their use in the formulation of well fluids.
