Patent attributes
Disclosed herein is an automated process of identifying shut-in parameters of a hydraulic fracturing operation from hydraulic fracturing treatment (HF) data. Also disclosed is a system and computer program product for automatically determining shut-in parameters from HF data. The HF data can be collected in real time during a HF from various sensors, equipment, or systems typically used in HFs or present at a well site. In one example, a method for automatically determining hydraulic fracturing parameters includes: (1) obtaining HF data, (2) determining a Rate Shut-In (RSI) time from the HF data, (3) determining a Well Shut-In (WSI) time using the RSI, and (4) calculating an Instantaneous Shut-In Pressure (ISIP) value based upon both the RSI and the WSI times, wherein determining the RSI time, the WSI time and calculating the ISIP value are automatically performed by one or more processors.
