CONTROL SYSTEM AND METHOD OF FLOWBACK OPERATIONS FOR SHALE RESERVOIRS

摘要

A flowback system and method employ a flowback model that characterizes fluid properties and rock mechanical properties of the reservoir during flowback in conjunction with measurement and analysis of chemistry and solids production with respect to the flowback fluid in order to maximize efficiency during the flowback operations, while mitigating formation damage and hydraulic fracture conductivity degradation. The methodology can define a safe drawdown operating zone for conducting flowback operations.
