ABSTRACT

A novel process for sand consolidation and sand production control has been developed. The procedure involves the use of bacteria that actively precipitate calcium carbonate as a cementing agent. A series of experiments was performed in the laboratory and showed that loose unconsolidated sand is transformed into a well cemented sand. Porosity was reduced by up to 50% and permeability was reduced by up to 90% in the areas where cementation took place. Facial plugging was avoided. Computer Assisted Tomography was used for the visualization of the cemented areas and the determination of the porosity distribution before and after the consolidation process.
