E6

Project Overview

The E6 oil project is centered around the development of 3D geological and petrophysical numerical models for the E6 oil-bearing structure. This structure is located in the Baltic Sea, offshore Latvia.

Objectives

• The primary objective is to assess the potential of the E6 structure for CO2 storage.
• To create detailed 3D models that can help in visualizing and analyzing the geological and petrophysical properties of the structure.
• To evaluate the feasibility and capacity of the E6 structure for CO2 sequestration.

Methodology

• Two models with different area and 3D volumetric grid size dimensions were developed to study the E6 structure comprehensively.
• The models incorporate various petrophysical and numerical seismic modeling techniques to simulate CO2 storage scenarios.
• The study involves analyzing the reservoir quality, petrophysical properties, and potential leakage paths through faults, which are critical for assessing the storage capacity and integrity of the structure.

Key Findings and Features

• The models help in understanding the complex geological structure and its suitability for CO2 storage.
• The study includes an analysis of the sedimentary basins in the Baltic States, including Estonia, Latvia, and neighboring regions, to determine the overall CO2 storage potential.
• The petrophysical properties of the host rocks, such as Cambrian sandstones, and their changes during CO2 storage are evaluated to ensure the long-term stability of the storage site.

Applications and Implications

• The E6 project contributes to the broader goal of reducing greenhouse gas emissions by identifying and characterizing potential CO2 storage sites.
• The findings can be applied to other similar geological structures in the Baltic Sea region, enhancing the regional capacity for CO2 sequestration.
• The detailed 3D models and numerical simulations provide valuable insights for policymakers, energy companies, and environmental agencies involved in carbon capture and storage (CCS) initiatives.
