Abstract
This specification discloses a process for the production of petroleum from a petroleum-containing subterranean reservoir employing an aqueous driving fluid containing, as a thickening agent, a biopolymer. The biopolymer is an extracellular heteropolysaccharide synthesized by an alga. A particular bipolymer is one synthesized by the alga Porphyridium aerugineum. The biopolymer may be employed in the aqueous driving fluid as an in-vivo solution or in a reconstituted form. There is also disclosed a process for the growth of, and synthesis of, biopolymer by an alga such as Porphyridium aerugineum.
