Abstract
This disclosure relates to an organic gel formulation composition for blocking fluids in naturally fractured carbonate reservoirs, for salinity conditions up to 31,870.50 ppm of total dissolved solids and temperatures up to 120° C., that is, for the purpose temporarily isolating areas of the reservoirs, that will be treated with chemical and radioactive products to quantify the oil remaining in them, the stability of the gel is controlled in a certain period of time, through the synergic effect of the supramolecular interaction between the components of the gel formulation. A disclosed composition may include 0.3 to 1% by weight of a copolymer of acrylamide butyl tertiary of sulfonic acid and acrylamide, and 0.12 to 0.4% by weight of phenol and from 0.18 to 0.6% by weight of hexamethylenetetramine.
