METHOD FOR DETERMINING SPATIAL DISTRIBUTION OF FLUID INJECTED INTO SUBSURFACE ROCK FORMATIONS

摘要

A method for determining spatial distribution of fluid injected into a subsurface rock formation includes injecting the fluid into the rock formation. The fluid includes therein electrically conductive solid particles dispersed in an electrolyte. An electromagnetic response of the formation is measured. The measured electromagnetic response is used to determine spatial distribution of the injected fluid.
