A multi-fractured well performance model for unconventional reservoirs
Heliyon, 2022 Due to the ultra-low permeability of unconventional reservoirs, transient state prevails for a considerable period. Despite this, fracture interference can cause an apparent no-flow boundary.

Optimal compression in natural gas networks: a geometric programming approach [PDF]
arXiv, 2013 Natural gas transmission pipelines are complex systems whose flow characteristics are governed by challenging non-linear physical behavior. These pipelines extend over hundreds and even thousands of miles. Gas is typically injected into the system at a constant rate, and a series of compressors are distributed along the pipeline to boost the gas ...

Nonlinearity and Domain Switching in a 3D‐Printed Architected Ferroelectric
Advanced Engineering Materials, EarlyView.By combining functional properties measurement with in situ 2D X‐ray microdiffraction experiments, it is shown that nonlinear polarization and strain responses of a 3D‐printed architected ferroelectric are driven by localized progression of domain switching, which depends on nonuniform electric‐field distribution as well as evolving stress fields.

Natural Gas Flow Equations: Uniqueness and an MI-SOCP Solver [PDF]
arXiv, 2018 The critical role of gas fired-plants to compensate renewable generation has increased the operational variability in natural gas networks (GN). Towards developing more reliable and efficient computational tools for GN monitoring, control, and planning, this work considers the task of solving the nonlinear equations governing steady-state flows and ...

Impact of Recent Discoveries on Petroleum and Natural Gas Exploration: Emphasis on India [PDF]
arXiv, 2010 Two discoveries have greatly impacted understanding relevant to the origination and emplacement of petroleum and natural gas deposits. One discovery, pertaining to hydrocarbon formation from methane broadens significantly potential regions where abiotic petroleum and natural gas deposits might be found.
