Title:
MICROBE-CONTAINING COMPOSITION FOR FILLING, AND APPLICATION OF SAME
Document Type and Number:
WIPO Patent Application WO/2018/159577
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a composition that can be used in filling gaps in earth, subterranean formations, etc., said composition having relatively low viscosity and being economically advantageous to a greater extent than previous filling materials, being unlikely to generate side effects, and furthermore having a broad range of application; and a method for applying the composition. The aforementioned purpose is achieved by: a composition containing urea-decomposing microbes that are capable of growing under high pressure, urea, calcium salt, and components suited to growth of the urea-decomposing microbes; and a mineral-filling method including a step for filling gaps in a mineral by bringing the composition into contact with the mineral.
