RAS is an oil reservoir dynamic analysis platform, which is based on analysis theory, experience, and analyzing regulations of oil gas dynamic. It orients production/oil dynamic analysis of oil reservoir management and research to Customers as follows:
For Oil Plant Geographic Research Institute: Tracks gas field/gas well production, current status of exploitation, analyze the reason of production fluctuation and development history, analyzes production law of oil field and single well, and make quarterly/ yearly analyzing plan.
For Research Institute: Medium-and-long term study and theme analysis.
For leaders: High-efficiency; understands the efficiency of oil reservoir development.
1） According to various job responsibilities and workflow, regulations, requirements of dynamic analysis, it analyzes various aspects in different levels;
2）Understand dynamic analysis work process of each position, cooperate, and share information, data, and achievements with each other;
3）Quickly obtain graph, curve, data from platform to help users to improve the quality and speed of dynamic analysis;
4）Update static and dynamic database to improve practical usage;
5）Update oil development index to guide users make decision;
6）Gather all achievements from dynamic analysis software.
According to users’ habitude, researches have two ways to carry the outwork, one is via platform, the other is via single well, group well, and oil field. Platform functions as follows:
3.1 Daily Dynamic Analysis
Through proximity warning indicator, production index, comparative analysis results and gradient drilling to discover problems from oil/water well production. Discover the reasons of problems by several ways, namely injection/production analysis, dynamic monitoring, work over operation, static data, the law of single well production after it proposes treatment and evaluates the efficiency of single well.
3.2 Monthly/Quarterly Dynamic Analysis
Monthly/Quarterly Dynamic Analysis is for accomplishment status of production index and development index. Meanwhile, it proposes treatment for the problems during production.
3.3 Yearly Dynamic Analysis
Analyze oil field via geologic characteristic, index completion, development effect evaluation, treatment evaluation, index forecasting etc. Moreover, it analyzes yearly dynamic analysis of oil reservoir, main problems during oil exploitation for production allocation the following year.
3.4 Period Dynamic Analysis
Through oil reservoir geographic characteristic, adaptability analysis of layer system and well network, development effective evaluation, oil remaining analysis, and index calculation etc. it recognizes geological characteristic, use water curve and indoor/outdoor test to confirm the final recovery ratio and recoverable reserves of oil reservoir. In addition, it analyzes water out behavior of oil layer, regularities distribution of remaining oil. It helps users to have a deep understanding on production rules of oil reservoir and analyzes the problems during oil reservoir development.
4.1 Analysis for Various Theme
According to the difference in oil reservoir types, operating fields, and characteristics, it forms a theme for various oil reservoir via allocation and localization.
It has many themes, such as heavy crude oil, planning establishment, potentiality analysis, and recoverable reserves demarcation etc.
4.2 Analysis for Pitch Point
Each analysis function includes analysis deadline which meet users need.
4.3 Analysis for Workflow
Build-in model provides users with materials they need.
4.4 Management Function
4.5 Analysis Methods
• Oil Reservoir Engineering Calculation
ARPS, permeability curve normalization, stream tube method, Jiye Wan methods, Logistic, water flooding feature curve.
• Oil Field Development Experience Formula
EF method, production decline method, water flood curve method, model method, method of resultant, core analysis method, geological synthesis method, mobility contrast method, well spacing density method, Xianzhang Tong methods, Qitai Yu methods, Jiye Wan methods etc.
4.6 Dynamic and Static State Mapping
It supports upload and manage geological vector diagram, and update coordinate. Through gas field geological structure graph, which includes alerting graph, contour graph, status graph of exploitation.it shows general status of gas field and single well.
4.7 Comprehensive Navigation Function, Various Target
It supports common analyzing target (gas field, block, and well) and user-defined target (user-defined unit). Analysts can combine (key) wells together to do analysis and comparison.
4.8 Well-adapted and flexible software
• PC Version: Load data in a fast and convenient way, and support off-line working
• Online Version: Adapt different database, e.g. develop production database, A2 database, SQLServer, Oracle etc.
• Import data from Excel files.
• Analyze regulation management, flexible graph setting, graph and data linkage, fix data and update without delay, contrastive analysis, One-click mapping, provide with map download function, and generate PPT.
