and water saturation The Core Pillars of the Craft 1 Reservoir Characterization This involves understanding the geological framework of the reservoir Were talking about analyzing seismic data well logs gamma ray resistivity density core samples and pressure measurements to build a 3D model of the reservoir This model reveals crucial details such as Porosity The percentage of void space in the rock that can hold fluids Think of a sponge higher porosity means more space to hold oil and gas Permeability The ability of the rock to allow fluids to flow through it A highly permeable rock allows for easier extraction Saturation The fraction of the pore space occupied by oil gas or water Higher oil saturation is desirable 2 Fluid Flow Simulation Once we have a detailed reservoir model we use sophisticated 2 software like Eclipse CMG or Petrel to simulate fluid flow within the reservoir These simulations help us predict how the reservoir will respond to different production strategies
