MEANS AND METHOD FOR ASSESSING THE GEOMETRY OF A SUBTERRANEAN FRACTURE DURING OR AFTER A HYDRAULIC FRACTURING TREATMENT

摘要

The present invention relates to methods of fracturing a subterranean formation including the step of pumping at least one device actively transmitting data that provide information on the device position, and further comprising the step of assessing the fracture geometry based on the positions of said at least one device or pumping metallic elements, preferably as proppant agents, and further locating the position of said metallic elements with a tool selected from the group consisting of magnetometers, resistivity tools, electromagnetic devices and ultra-long arrays of electrodes. The invention allows monitoring of the fracture geometry and proppant placement.
