Project–1 Modeling and simulation of field production
networks
The objective of this project is to develop a simulator for steady
state production in oil and gas fields that simulate the behavior of the
production and injection wells, the gathering system and the injection
systems. It will answer the question of "how will the system behave in
a given situation" and will assists in design, operation and monitoring
of production systems. The project will address the following issues:
-
Representation of production network topology for simple network computations
-
Network solvers
-
Steady state multi phase flow modeling in pipe sections
-
Compositional approach using Equation of State (EOS) methods for flow properties
calculations
-
Lumping and de-lumping streams
-
Thermal models (compositional approach to energy transfer)
-
Tuning of production system performance for performance monitoring and
allocation needs
-
Efficient and accurate integrators for pressure and temperature calculations
-
Steady state modeling of gaslift production system (production-injection)
-
Optimal gas allocation schemes
-
Automatic control and monitoring of steady optimal production systems
-
Interfaces with reservoir simulators and process simulators
Project-2 Monitoring and analyst of field production
performance
The objective of this project is to develop a system that monitors
the production performance of the wells and identifies wells where deliverability
has deteriorated or reserves diminished. The intention is to use production
records, together with variety of relevant reservoir, petrophysical
and well completion data, to establish a well production model. The model,
properly maintained and routinely adjusted to account for changes in the
reservoir, should correctly describe the production performance of the
wells, explains its characteristics and produces good production predictions.
It should maximizes the value of measurements performs continuously without
conducting expensive special tests or surveys.
Ultimately, the result will be an effective and cost efficient approach
to utilize measured data for production forecasting, and tuning reservoir
and production management strategies
The project will focus on automation of interpretation techniques
and will address the following issues:
-
Well surveillance and automatic data storage
-
Quality control and filtering of the gathered data
-
Routine reviews and analysis of the observed performance
-
Identification and explanation of anomalies
-

-

-
Free water and gas production (crusting, conning, cusping)
-
Effect of pressure support (water/gas injection),
-
Communication of reservoir units
-
Distinguish between areal heterogeneity and layered effect
-
Individual layers production
-
Criteria for initiating strategic studies
-
Implications of reservoir management measures
-
Well intervention and completions changes
-

-
Needs for wellbore surveys
-
Introduction of artificial lift
-
Adjustments and modifications of production gathering systems
Project-3 Modeling and simulation of unloading of gaslift
wells
This project intends to develop a simulator to simulate the process
of unloading of gaslift oil wells and gaslift fields. The simulator will
be used to study the stability of the process and to develop strategy for
optimizing gas injection distribution during the unloading process. Some
of the issues involved are:
-
Simplified approach for modeling transient multiphase flow in wells (modified
two-fluid model or drift-flux approaches)
-
Modeling and simulation of injection point transfer
-
Simplified approach for thermal calculation during unloading process
-
Transient response of reservoir during the unloading process
-
Flow characteristics of gas throttling devices
-
Total system simulator
-
Simulating wide range of production cases
-
Developing criteria for optimizing unloading process
-
Investigate the dynamic characteristics of the unloading process
-
Investigate the stability of the process (injection and production parts)
-
Interface with control simulation tool kits
