Real-time Well Bashing Decision via Dynamic Diversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional diversion techniques in hydraulic fracturing fail to account for real-time operating conditions, leading to inefficient distribution of treatment fluids and potential well bashing, where treatment fluid from one well interferes with production in adjacent wells.
Innovation Solution
A system and method that use real-time measurement data from multiple wells to determine flow distribution and fracture lengths, deploying diverting materials to control well bashing by adjusting the treatment plan dynamically during stimulation treatments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional predefined treatment schedules are used for diversion, then operational simplicity is maintained, but flow distribution uniformity deteriorates and well bashing occurs
Solution Approach 1:
The patent transitions from static predefined treatment schedules to dynamic real-time adjustment of diversion decisions. Treatment parameters are continuously modified based on live monitoring data from multiple wells, allowing the system to adapt to changing subsurface conditions and maintain optimal flow distribution throughout the stimulation process.
Solution Approach 2:
The system implements closed-loop feedback by monitoring flow distribution in real-time using measurements from multiple wells and using this information to adjust diversion decisions. The feedback mechanism compares actual flow distribution against target distributions and triggers corrective diversion actions to eliminate deviations and prevent well bashing.
2Manufacturing precision
If real-time monitoring and adjustment systems are implemented, then flow distribution uniformity is improved and well bashing is prevented, but system complexity increases
Solution Approach 1:
The system integrates multiple functions into a unified platform that combines real-time data acquisition from multiple wells, flow distribution calculation, fracture length estimation, diversion decision-making, and treatment adjustment. This multi-functional integration reduces the need for separate systems and minimizes overall complexity while achieving precise flow control.
Solution Approach 2:
The system performs self-diagnosis and self-adjustment by automatically detecting flow distribution deviations and initiating corrective diversion actions without external intervention. The automated decision-making process reduces the need for complex human-operated control systems while maintaining high precision in flow distribution management.
3Object-affected harmful factors
If diversion material is deployed based on real-time fracture length determination, then well bashing is controlled, but measurement and decision-making time increases
Solution Approach 1:
The system performs preliminary estimation of fracture lengths and identifies potential well bashing risks before they fully develop. By proactively determining fracture geometry and predicting interference scenarios, the system can prepare diversion decisions in advance, reducing the reactive response time and preventing harmful effects before they occur.
Solution Approach 2:
The patent replaces time-consuming physical measurement methods with computational modeling and data processing techniques. Fracture lengths are determined through mathematical calculations based on flow distribution data and pressure measurements, eliminating the need for direct downhole measurement tools and significantly reducing decision-making time.
Data Source
AI summary
A system includes a processor(s), and a memory coupled to the processor(s) having instructions stored therein. When executed by the processor(s), the instructions cause the processor(s) to perform functions to: apply a treatment for stimulating production to at least a first well in a subterranean formation; determine a flow distribution based on at least one of a first-well measurement or a second-well measurement, the first-well measurement taken at the first well, and the second-well measurement taken at a second well; determine a length of a fracture between the first and second wells, based on the determined flow distribution; determine if the applied treatment at the first well interferes with the second well, based on the determined length of the fracture; and apply a diverting material at the first well if it is determined that the applied treatment interferes with the second well, in order to control well bashing.
