Measuring Up: Understanding "Measurable" in Oil & Gas

This document expands on the provided text, breaking it down into chapters focusing on Techniques, Models, Software, Best Practices, and Case Studies related to measurability in the oil and gas industry.

Chapter 1: Techniques for Measurement in Oil & Gas

The ability to accurately measure various parameters is fundamental to the oil and gas industry. This chapter details the core techniques employed across the lifecycle.

1.1 Direct Measurement Techniques: These methods involve the direct quantification of a physical quantity using specialized instruments.

• Flow Measurement: Devices like orifice plates, venturi meters, and ultrasonic flow meters measure the volumetric flow rate of oil and gas. Accuracy depends on factors such as fluid properties and proper installation.
• Pressure Measurement: Pressure gauges, transducers, and pressure transmitters are used to monitor wellhead pressure, pipeline pressure, and reservoir pressure. Calibration and regular maintenance are crucial for reliable data.
• Temperature Measurement: Thermocouples, resistance temperature detectors (RTDs), and thermistors measure temperature in various parts of the process, impacting density calculations and other critical parameters.
• Level Measurement: Techniques including radar, ultrasonic, and hydrostatic level sensors determine the fluid level in tanks and reservoirs. The choice depends on factors such as tank material and fluid properties.
• Density Measurement: Density meters, using techniques such as coriolis or vibrating element methods, determine the density of fluids, which is crucial for calculating mass flow rates and determining fluid composition.

1.2 Indirect Measurement Techniques: These methods infer a quantity based on related measurable parameters.

• Geophysical Surveys: Seismic surveys utilize sound waves to create images of subsurface formations, indirectly measuring reservoir size and properties like porosity and permeability.
• Well Logging: Tools lowered into boreholes measure various properties of the formation, providing data on porosity, permeability, and fluid saturation.
• Remote Sensing: Satellite imagery and aerial photography can be used to monitor pipelines, detect oil spills, and assess environmental impact. Analysis of these images provides indirect measurements of environmental changes.
• Production Decline Curve Analysis: Analyzing historical production data helps predict future production rates, indirectly measuring remaining reserves.

1.3 Laboratory Analysis: Sample analysis plays a crucial role in determining fluid properties.

• Gas Chromatography: Determines the composition of natural gas, crucial for evaluating its quality and market value.
• Fluid Analysis: Laboratories analyze oil and water samples to determine properties like API gravity, viscosity, and sulfur content.

Chapter 2: Models for Quantifying Oil & Gas Parameters

Numerous models are utilized to estimate unmeasured quantities, predict future performance, and manage risk.

2.1 Reservoir Simulation: Complex numerical models simulate fluid flow and production within a reservoir, using data from geophysical surveys and well logs to predict reservoir performance under various production scenarios.

2.2 Material Balance Calculations: These calculations estimate reservoir properties and remaining reserves based on production history and pressure data.

2.3 Decline Curve Analysis: Mathematical models predict future production rates based on historical production data, vital for resource planning and investment decisions.

2.4 Production Forecasting Models: Integrate reservoir simulation, material balance, and decline curve analysis to generate comprehensive production forecasts.

2.5 Economic Models: Evaluate the profitability of oil and gas projects, incorporating factors such as production costs, revenue, and resource depletion rates. These models often integrate output from other models.
