4D passive microseismic methods uses the induced seismicity and performs the mapping of artificial fractures. This suite of methods is called the MicroSeismicPRM (MSPRM) and includes method for Short-Term monitoring ST-MSPRM (Multistage Hydraulic Fracturing) and method for Long-Term monitoring LT- MSPRM ( Waterflooding, Estimation of Drainage Area, Underground Gas Storage)
