VEGETABLE ORIGIN SURFACTANTS FOR FORMING STABILIZED, HIGH-EFFICIENCY FOAM FOR GAS WELLS.

摘要

The present disclosure is related to the application of vegetable origin surfactants for forming stabilized, high-efficiency foam for gas wells. Liquids and bars develop stable foam at high temperatures in deep wells; and in extremely high temperature wells, said surfactants usually dissolve within 30 to 90 minutes depending on the temperature, salt content and water movement. The bars are used primarily to dislodge water from wells and increase production, the foam decreases the hydrostatic pressure increasing the production and further improving foaming until the well discharges. The bars can be used to remove the condensate and water from oil wells; and the condensate from flowing gas wells, for wells with more than 75% of the condensate. The liquids composed with this formula are injected by capillary tubing at the bottom of the well and distributed by a diffuser stimulating gas production by increasing the permeability of the formation.
