Halliburton 2021 Annual & Sustainability Report Environmental 44 Halliburton Landmark software, Landmark adapts E&P workflows to consider the parameters that are important for safe CO storage, 2 To support Halliburton 4.0, Halliburton Landmark offers identify suitable aquifers, screen areas for further a suite of geoscience software products that enable investigation, and model them using technologies that our customers to explore and produce hydrocarbons. In we developed to understand the injection and migration 2021, Halliburton shifted Landmark products further into of captured CO . Our technology helps customers answer 2 the sustainability space. Here are a few examples of our critical questions such as: products that support the world’s energy transition: • Where can we store CO ? 2 Neftex® PROSPECT software, which we developed in • How much CO can we inject, and can we inject CO 2 2 2021 and will launch in the first quarter of 2022, supports at a sufficient rate? critical mineral exploration. Electrification of transport • Can we store it safely? and industrial processes is a key component of global decarbonization ambitions. However, this initiative • What is a site’s storage capacity over its lifetime? requires a vastly increased supply of metals and minerals • Will the CO remain in the geological storage tank for success. Renewed investment in discovering 2 over time without leaking? additional resources will be the key to meet this demand. We also focus our efforts to enhance our iEnergy® Landmark adapts proven oil and gas exploration workflows to aid in the hunt for minerals that are critical platform, the industry’s first hybrid cloud environment to the energy transition. dedicated to E&P. By using machine learning, we can better manage and mitigate carbon emissions from Storage of carbon dioxide (CO ) in ancient rock strata is set our operations. 2 to become a major contributor to emissions reduction.

With Neftex Predictions and DecisionSpace 365 This database is included in Neftex® PROSPECT software. Areas in color denote when Earth’s tectonic features were active. Because many critical minerals are found in zones of active tectonism, this information can help to identify areas for closer attention in the search for specific minerals.
