Microseismic Mapping of Hydraulic Fractures Using Multi-Level Wireline Receivers

摘要: Hydraulic fracture diagnostic experiments are being conducted at the GRI/DOE Multi-Site (M-Site) located in Piceance basin of Colorado. Tests described this paper use a multi-level advanced-receiver system to build on previous work that showed advantages using single advanced receiver monitor microseisms. The current test has four-level monitoring four separate over one week period, and includes velocity tomographic survey detailed orientation survey. fractures were monitored from an offset well 210 ft away treatment results these tests show developing asymmetrically with time, yielding fracture-wing asymmetry 2 :1. initially grows within pay zone essentially its total length, then begins grow upward, later time downward. Comparison models gives only partial agreement final size.
