Study Notes
Production Performance in Oil and Gas
- Critical for the efficiency and profitability of oil and gas operations.
- Key techniques include data acquisition, bubble mapping, decline curve analysis, and material balance analysis.
Data Acquisition
- Diverse sources of data are essential for accurate evaluation:
- Seismic surveys provide subsurface geological data.
- Core analysis gives information on rock properties.
- Well logging assesses the physical and chemical properties of reservoir formations.
- Pressure transient analysis evaluates the pressure response in the reservoir.
- Production and injection monitoring tracks output and input volumes.
- Tracer surveys help in understanding fluid movement within reservoirs.
Bubble Mapping
- A technique for visualizing spatial trends in production data.
- Helps identify trends, which inform operational decisions.
Decline Curve Analysis
- Used for forecasting future production based on historical data.
- Types of declines include:
- Exponential decline indicates a constant percentage decrease over time.
- Hyperbolic decline reflects a more variable decrease.
- Parabolic decline shows a decrease that slows down over time.
Oil Reservoir Material Balance
- Based on the conservation of mass principle:
- Mass in tank = original mass + mass entering - mass exiting.
- Measurable quantities include cumulative fluid production, injection volumes, reservoir pressure, and fluid properties.
- Data measurements over time are essential to establish long-term trends.
Depletion Drive Mechanisms
- Various mechanisms drive oil recovery, including:
- Solution gas drive utilizes dissolved gas in the oil.
- Gas cap drive involves gas accumulation on top of the oil layer.
- Water drive relies on water injection to push oil towards the production well.
Inflow Performance Relationships
- Key components include controlling reservoir inflow and tubing outflow to determine optimal operating points.
Advantages and Disadvantages of Production Performance Evaluation
- Advantages include enhanced decision-making and improved efficiency in resource extraction.
- Disadvantages may involve high costs of data acquisition and analysis, as well as reliance on potentially inaccurate models.
