1Productivity
If hydraulic fracturing treatment is performed in a treatment wellbore, then hydrocarbon production from the geologic formation is enhanced, but understanding and characterizing the fracture interactions between wellbores becomes difficult
Solution Approach 1:
The system uses pressure sensors in monitor wellbores to detect pressure changes caused by hydraulic fracturing in treatment wellbores. This feedback mechanism provides real-time information about fracture propagation and interactions, enabling characterization of FDI types (direct fluid communication, fluid migration, poroelastic response) while maintaining enhanced hydrocarbon production
Solution Approach 2:
Pressure sensors act as intermediaries between the hydraulic fracturing process and the monitoring system. These sensors detect pressure changes in monitor wellbores that result from fractures in treatment wellbores, translating complex subsurface fracture interactions into measurable pressure data that can be analyzed to determine FDI types
2Measurement precision
If pressure sensors are installed in monitor wellbores to detect fracture interactions, then FDI determination accuracy is improved, but system complexity and cost increase
Solution Approach 1:
The pressure sensors in monitor wellbores serve multiple functions: they detect pressure changes from hydraulic fracturing, characterize FDI types, and provide information for optimizing both current and future well completions. This multi-functionality justifies the added system complexity by delivering comprehensive insights from a single monitoring infrastructure
Solution Approach 2:
Monitor wellbores with pressure sensors are installed in advance before hydraulic fracturing treatments begin. This preliminary action enables the system to capture and record pressure response data from future fracturing operations, allowing for accurate FDI determination without requiring retroactive installation of monitoring equipment
