Defoamer compositions are disclosed and methods for making and using same, where the defoamer has universal applicability at low concentrations. The defoamer compositions include between 40 vol. % and about 80 vol. % distilled water (other waters may be used instead), 10 vol. % and about 30 vol. % of silicon anti-foam agent and between about 10 vol. % and about 30 vol. % of active silicon anti-foam agent. The defoamer compositions are used in amount of less than or equal to 200 ppm in all foamed downhole fluid systems.

Defoamer formulation and methods for making and using same

Methods for using complementary surfactant systems and downhole fluids, where the systems are tailored to foam the fluids, which include the analyzed crude and/or condensate.

Methods for using complementary surfactant compositions

Non-toxic, biodegradable base fluids are disclosed for use in making downhole fluids, where the base fluids include blends of paraffins, olefins, naphthenes, esters, and oxygenates, having low viscosities, having a pale-yellow color, having a flashpoint of &#x3e;80&#xb0; C. (175&#xb0; F.) and have a pour point of about 19&#xb0; F. Methods for making and using fluids include the base fluids of this invention are also disclosed.

Environmentally friendly base fluids and methods for making and using same

Complementary surfactant systems and downhole fluids made using the systems are disclosed along with methods for making and using same, where the surfactant systems include from 0 wt. % to 100 wt. % of a first surfactant subsystem, from 100 wt. % to 0 wt. % of a second surfactant subsystem, and from 0 wt. % to 100 wt. % of a solvent subsystem based on the wt. % of the surfactant subsystems, where the system is tailored to foam the fluid including the analyzed crude and/or condensate.

Complementary surfactant compositions and methods for making and using same

New oil-based foam drilling fluids for oil and/or gas wells include a base oil, a foaming agent and a polymer including at least one aromatic olefin monomer and at least one diene monomer. The polymer improves foam properties rendering a foam stable at temperatures at or above 350&#xb0; F.

Enhanced oil-based foam drilling fluid compositions and method for making and using same

A new class of secondary emulsifying agents for use in inverted mud and other inverted system is disclosed and method for making and using same.
