Production performance evaluation of energized fracturing fluids in unconventional formations
Pursuit of unconventional gas and oil has prompted the development and adoption of innovative fracturing solutions. Energized fracturing is one promising technology that can be an effective alternative to mainstream slickwater or hybrid fracturing fluids in many applications. Yet, field use of …

Prevalence, persistence and consequences of microorganisms within oil field environments and mitigation strategies
… have been performed on a limited number of unconventional shale formations in the United States (e.g., the Marcellus Formation) and do not represent the geological conditions in other unconventional formations. This work focuses on less studied unconventional tight formations in the Permian …

Fracture optimization based on gradient descent methodology
… as well as the spacing of hydraulic fractures in unconventional reservoirs. In our program, the cumulative discounted Net Present Value (NPV) is selected as the target function and the gradient descent methodology is adopted as the optimizer. Relying on the gradient information, gradient descent …

Modeling fluid imbibition for hydraulic fracturing and its implications on unconventional hydrocarbon recovery
… characteristics and subsurface conditions of unconventional formations, including capillarity, diffusion, osmosis, and adsorption. To investigate the impact of the fluid imbibition process on post-treatment well performance and oil recovery, comprehensive modeling efforts are made. In this …

Desalination systems for the treatment of hypersaline produced water from unconventional oil and gas processes
… deep well injection, can be unfeasible in many unconventional resource settings as a result of regulatory, environmental, and/or economic barriers. Consequently, on-site treatment and reuse-a part of which is desalination-has emerged as a strategy in many unconventional formations. However, …

Production Analysis and Enhancement in The Unconventional Tight Formations
… of the development efficiency in these formations. Production modelling and analysis have been used in the oil and gas industry for a long time for the purpose of asset evaluation and project design. In this study, a new methodology for complex production profile analysis is first …
