Mathematical Model of Spontaneous Potential Well Logging and Its Numerical Simulation: Unlocking Earth's Subsurface Secrets

to Spontaneous Potential Well Logging

Spontaneous Potential Well Logging (SP) is a geophysical well logging technique that measures the electrical potential difference between an electrode in the borehole and a reference electrode at the surface. The SP log provides valuable insights into the electrical properties of the rock formations traversed by the wellbore, enabling geologists and petrophysicists to assess formation characteristics, identify fluid-filled zones, and evaluate hydrocarbon potential.

The Mathematical Model

The mathematical model of SP well logging is based on the electrokinetic principles governing the flow of ions in porous media. The model considers the interplay between the electrical potential, ion concentrations, and rock properties. By solving the governing equations, the SP response can be predicted for different formation conditions.

The numerical simulation of the SP model enables us to investigate the impact of various parameters on the SP response. This provides a powerful tool for analyzing and interpreting SP logs, identifying formation characteristics, and predicting fluid properties.

Applications of the Model

The mathematical model of SP well logging has extensive applications in formation evaluation and reservoir characterization. Some notable applications include:

• Identification of Permeable Zones: SP logs exhibit characteristic bell-shaped curves in permeable formations. The model helps identify these zones and estimate their permeability.
• Estimation of Formation Water Resistivity: The SP response is influenced by the resistivity of the formation water. The model can be used to infer formation water resistivity, which is crucial for hydrocarbon saturation calculations.
• Evaluation of Clay Content: Clay minerals affect the electrical properties of rocks. The model incorporates clay content as a parameter, enabling the estimation of clay content from SP logs.
• Hydrocarbon Saturation Analysis: The SP response is sensitive to the presence of hydrocarbons. The model can be used to predict hydrocarbon saturation, aiding in reservoir evaluation.

The mathematical model of Spontaneous Potential Well Logging and its numerical simulation provide a powerful framework for understanding and interpreting SP logs. By combining theoretical concepts and numerical modeling, the book empowers readers to unravel the secrets of the Earth's subsurface, enabling informed decision-making in exploration and production activities.
