Study Notes
Well Measurement Types
- Physical measurements assess the hole conditions directly, providing real-time data on structural integrity.
- Spontaneous measurements do not include parameters such as pressure or temperature.
Logarithmic Scale in Well Logging
- A logarithmic scale helps visualize a wide range of values, making it easier to detect small changes in formation properties.
Tools and Measurements
- A gamma-ray (GR) tool employs a GR source and detector to conduct induced measurements, helping identify lithology and fluid content in formations.
Valid Uses of Well Logs
- Well logs can be utilized for formations evaluation, but they should not be used for direct drilling decisions, which do not involve logging data evaluation.
Logging Types
- The logging type involving a source that generates a signal traveling through the formation towards detectors is commonly known as electrical logging.
Petroleum Engineer Responsibilities
- A petroleum engineer’s role includes recognizing hydrocarbon zones, assessing characteristics, and evaluating economic viability related to field operations.
Well Log Creation
- Depth-based measurement of physical properties, such as resistivity or porosity, is essential for constructing well logs that reflect subsurface conditions.
Purpose of Well Logging
- Well logging serves the purpose of formation evaluation, facilitating the understanding of subsurface geology, and aiding in reservoir management.
Petrophysical Properties in Hydrocarbon Evaluation
- Key factors in evaluating hydrocarbon zones include permeability and saturation; however, economic market conditions are often overlooked in the drilling and production assessment.
