Conduct an RTA analysis on both parent wells to determine the extent of the depletion as a result of production drawdown for integration into the fracture model. Generate a hydraulic fracture depletion model using the calibrated child well fracture model fracture...

... fracture geometries, well interactions, and well performance. The dataset in this project includes three child wells and one parent well, landed within two targets of the Wolfcamp B reservoir in the Midland Basin. The following workflow helped the operator understand the completion design effectiveness...

... Abstract The analyses of parent-child well performance is a complex problem depending on the interplay between timing, completion design, formation properties, direct frac-hits and well spacing. Assessing the impact of well spacing on parent or child well performance is therefore challenging...

...Model Description and Workflow We developed a workflow to simulate parent-child well interactions by integrating a hydraulic fracturing simulator (Multi-Frac-NF) and a geomechanics coupled reservoir simulator (Multi-Frac-3D). Multi-Frac-NF ( Shrivastava and Sharma, 2018 ) is a displacement...

... In this study, the signals from both parent and child well are monitored. Signal characterization is based on poromechanics principles, specifically the stress and fluid pressure fields that surround a growing hydraulic fracture in the rock, described by Das et al. (2019) . As hydraulic...
