About Us

PETROLERN LLC is an international research, consulting and training company, providing the energy industry with high-quality services as well as practical and specialized training courses in different subsurface engineering and geosciences disciplines. Our policy at PETROLERN is to provide high-quality services while openly discussing uncertainties in the results with our clients. We pursue challenging projects where we can apply our innovative solutions and problem-solving skills. Our well-reputed and experienced team are ready to provide solutions to your challenging problems.

Unconventional Resources

We pay special attention to the optimized development of unconventional resources, including shale gas, shale oil, CBM, heavy oil and tight gas. These energy sources are fast-growing markets and have been recognized as the forefront of the future energy worldwide. It is imperative that we harness the best available technologies for efficient recovery of these resources. In PETROLERN, we believe that successful production from unconventional resources requires unconventional thinking.

CO2 Sequestration

Long-term CO2 storage in geologic formations is an effective response to growing concerns about climate change resulting from increased carbon dioxide concentrations in the atmosphere. The key to the effective injection of CO2 into the subsurface formations, including depleted oil and gas reservoirs for enhanced oil recovery, is a detailed characterization of the formation properties, in-situ stresses, natural fractures network, seal capacity of cap rock and formation pressure, in addition to Monitoring, Verification, and Accounting (MVA) to confirm permanent storage of CO2. This is our expertise at PETROLERN.

Deep Water and HPHT Fields

Drilling and production operations in deep-water and HPHT fields are the most challenging operations in the oil and gas industry. Due to a significantly narrow mud weight window in deep water and HPHT environments, safe and optimum drilling, completion and production require advanced knowledge and cutting-edge technologies. PETROLERN’s experienced and creative team are ready to provide solutions to your problems in these challenging environments.

Geothermal Energy

To maximize sustainability of geothermal reservoirs, especially Enhanced Geothermal System (EGS), and ensure safe and cost-effective subsurface operations such as drilling, completion, stimulation and injection, knowledge of subsurface state of stress, rock properties, natural fractures and temperature is essential. We strive to produce the most reliable estimations of these parameters by means of advanced analytical and numerical models in combination with signal processing and machine learning techniques. In PETROLERN, we focus on clean energy as much as fossil energy.
