Abstract
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.

- a second surfactant subsystem comprising silicon surfactant, and
- 0 wt. % to 100 wt. % of a solvent subsystem based on the wt. % of the surfactant subsystems selected from the group consisting of terpenes and mixture of terpenes derived from citrus plants including a biodegradable blend of paraffins, olefins, naphthenes, esters, and oxygenates, d-limonenes, orange terpenes, lemon terpenes, grapefruit terpenes, orange oil, lemon oil, other citrus terpenes, other citrus oils, or mixtures and combinations thereof,
- where a weight ratio of the first surfactant subsystem to the second surfactant subsystem is between about 10:1 and about 1:10 and where the composition tailored to foam a fluid including a spectroscopically analyzed crude and/or condensate present in a producing formation.
A drilling fluid composition comprising a surfactant system including:
- a first surfactant subsystem comprising a fluorinated surfactant including fluoroaliphatic polymeric ester (FAPE) surfactants,
