Assignee:

Shell Oil Company - Houston TX

International Classification:

E21B 33/138

US Classification:

166295, 16625014, 166300, 175 72

Abstract:

A method for strengthening a wellbore with an exposed geological formation, the method including: determining or estimating material properties of the exposed geological formation; determining changes necessary in material properties of the exposed geologic formation to achieve desired improvements in property of the exposed geologic formation; and treating the geological formation to improve material property values by injecting a formulation that hardens in-situ to form a geosynthetic composite. In another aspect, an apparatus for utilizing the described method with minimal handling of chemicals includes is an automated in-line chemical metering and pumping apparatus that requires no large mixing tank.
