Understanding Permeability in Oil Reservoir Rocks: Key Concepts from the Lecture Permeability is a fundamental property of reservoir rocks that directly impacts the flow of fluids , including oil and gas, within a reservoir . In this article, I will outline the essential points covered in a detailed lecture on permeability , which you can download for free at the end of this post. Understanding Permeability in Oil Reservoir Rocks: Key Concepts from the Lecture What is Permeability? Permeability refers to the ability of a rock to transmit fluids through its pore spaces. It plays a crucial role in determining how easily oil and gas can be extracted from a reservoir . Permeability depends on the size, shape, and connectivity of the pores in the rock, and it is typically expressed in millidarcies (mD). Types of Permeability The lecture explains various types of permeability : Absolute Permeability: This is the permeability of a rock when it is fully saturated with a single fluid, suc

Lecture about Porosity in Reservoir Rocks PPT

Understanding Porosity in Reservoir Rocks Porosity  is a critical rock property in the oil and gas industry. It defines the fraction of a rock’s volume that is occupied by pore space—those tiny voids where fluids (such as oil, gas, and water) can reside. Imagine these pores as the reservoir’s storage compartments, waiting to hold hydrocarbons. Understanding Porosity in Reservoir Rocks The Basics of Porosity 1. Definition:   Porosity quantifies the storage capacity of a rock. It’s the ratio of the pore volume to the total volume (also known as the bulk volume). Mathematically, we express it as:   [ \phi = \frac{{V_p}}{{V_b}} ]   Here: (V_p) represents the pore volume. (V_b) is the bulk rock volume. 2. Types of Porosity: Total Porosity ((\phi_t)): This includes both connected and isolated pores. Connected pores can transmit fluids, while isolated pores cannot. Effective Porosity   ((\phi_e)): Only considers connected pores—the ones that matter for fluid flow. Visualizing Porosity Im
