| titleOfInvention | Method of monitoring of hydraulic fracture closure stress with tracers (variants) |
| abstract | The present disclosure relates to the hydrocarbon production, in particular to measuring the fracture closure pressure in a formation penetrated by a wellbore using marker agents. According to this disclosure, a wellbore is provided; a clean fracturing fluid is injected into the wellbore thus creating a fracture in the formation; the fracturing fluid is injected into the well, wherein the fracturing fluid comprises a mixture of a proppant and one or more groups of capsules with the predetermined range of breaking strength values and comprising a marker agent that corresponds to each predetermined range of breaking strength values, wherein capsules of different groups comprise different marker agents and are designed to precipitate in the fracture and release the marker agent in case the fracture closure pressure exceeds the predetermined range of breaking strength values due to fracture closure; the marker agent production to the surface is provided; the marker agent is detected at the surface; and the fracture closure pressure is measured based on the detected marker agent based on the breaking strength range of the capsule in the corresponding group of capsules. |
