Unconventional gas resources from tight-sand and shale gas reservoirs have received great attention in the past decade around the world because of their large reserves and technical advances in developing these resources. As a result of improved horizontaldrilling and hydraulic-fracturing technologies, progress is being made toward commercial gas production from such reservoirs, as demonstrated...

As a representative of emerging unconventional energy, shale gas has the characteristics large reserves, long production cycle, and environmental protection. However, due to complex geological reservoirs, economic development reservoirs is difficult. In this paper, on basis full investigation relevant literature, according permeability mechanism productivity horizontal wells in low-permeability...

This paper presents the results of a simulation study designed to evaluate the applicability of an Arps decline curve methodology for assessing reserves in hydraulically-fractured wells completed in tight gas sands at high-pressure/high-temperature (HP/HT) reservoir conditions. We simulated various reservoir and hydraulic-fracture properties to determine their impact on the production decline b...

Natural gas comprises almost one-fourth of all energy used in the U.S. New technologies, sometimes referred to as “unconventional” have enabled the production of more natural gas and have expanded domestic energy reserves. Natural gas is generally recognized as a clean-burning fuel source, producing less greenhouse gas (GHG) emissions per quantity of energy consumed than either coal or oil. How...

The worldwide energies’ price continues to rise again. More countries pay more attention to unconventional energies. Shale gas is one of the significant unconventional energy sources. With the successful development of shale gas in the United States, more and more countries and corporations focus on the shale gas exploitation. The large recoverable reserves of shale gas will ensure China's ener...

This paper examines the volumes of oil that can and cannot be used up to 2035 during the transition to a low-carbon global energy system using the global energy systems model, TIAM-UCL and the ‘Bottom up Economic and Geological Oil field production model’ (BUEGO). Globally in a scenario allowing the widespread adoption of carbon capture and storage (CCS) nearly 500 billion barrels of existing 2...

We propose a theoretical model based on the bank lending channel to assess the ability of lending facilities and swap programmes to a¤ect the credit interest rate. The model predicts the success of both unconventional monetary measures in reducing the credit interest rate under very general conditions. The comparison between measures reveals the outperformance of lending facilities over swap pr...
