Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional petroleum reservoir models often focus on individual wells without adequately considering reservoir properties, leading to incomplete understanding of fluid interactions and flow paths, which limits their predictive capabilities for multi-well systems.
Innovation Solution
A high-resolution advanced 3D transient model is generated by integrating pressure transient data into a static geological model, allowing for the calibration of multiple wells and accounting for interference between them, thereby capturing realistic fluid dynamics and reservoir properties.

Engineering Contradiction Analysis
1Device complexity
If conventional well models are used focusing on individual well performance, then the model complexity is reduced, but the accuracy of predicting multi-well system behavior deteriorates
Solution Approach 1:
The reservoir is divided into multiple sectors, each containing one or more wells, allowing the complex multi-well system to be modeled as separate but interconnected sectors. This segmentation enables detailed modeling of fluid interactions between wells while maintaining manageable model complexity through modular structure.
Solution Approach 2:
Multiple well models are merged into a unified reservoir model that captures interactions between wells. The model integrates pressure transient data from multiple wells simultaneously, allowing the system to predict multi-well behavior accurately by considering cross-well fluid flow and interference effects.
2Measurement precision
If pressure transient data from multiple wells is integrated into the model, then the measurement precision of reservoir properties improves, but the device complexity increases
Solution Approach 1:
The model applies different levels of detail and calibration to different regions of the reservoir based on local characteristics. Areas with available pressure transient data from multiple wells receive enhanced calibration and resolution, while regions with less data use coarser modeling approaches, optimizing the balance between measurement precision and model complexity.
Solution Approach 2:
The model transitions from static geological models to dynamic transient models by adding the time dimension. Pressure transient data from multiple wells is integrated across spatial and temporal dimensions, enabling three-dimensional characterization of reservoir properties including temporal variations in fluid flow and pressure distribution.

AI summary
Systems and methods include a method for generating a high-resolution advanced three-dimensional (3D) transient model that models multiple wells by integrating pressure transient data into a static geological model. A crude 3D model is generated from a full-field geological model that models production for multiple wells in an area. A functional 3D model is generated from the crude 3D model. An intermediate 3D model is generated by calibrating the functional 3D model with single-well data. An advanced 3D transient model is generated by calibrating multi-well data in the functional 3D model.
