Intelligent fracture creation for shale gas development
Shale gas represents a major fraction of the proven reserves of natural gas in the United States and a collection of other countries. Higher gas prices and the need for cleaner fuels provides motivation for commercializing shale gas deposits even though the cost is substantially higher than traditional gas deposits. Recent advances in horizontal drilling and multistage hydraulic fracturing, whi...
متن کاملPermeability Change Caused by Stress Damage of Gas Shale
Stress damage of shale during the uniaxial loading process will cause the change of permeability. The study of stress sensitivity of shale has focused on the influence of confining pressure on shale permeability and the change of shale permeability during the loading process of axial stress is lacking. The permeability of gas shale during loading process was tested. The results show that shale ...
متن کاملIntegrating Embedded Discrete Fracture and Dual-Porosity, Dual-Permeability Methods to Simulate Fluid Flow in Shale Oil Reservoirs
Abstract: The oil recovery factor from shale oil remains low, about 5 to 7% of the oil in place. How to increase oil recovery from shale oil reservoirs is attracting more and more attention. CO2 huff-and-puff was historically considered one of the best approaches to improve the oil rate. Most previous simulation studies have been based on dual porosity, but simulation results from dual-porosity...
متن کاملHow fracture interference impacts Woodford shale gas production
An integrated analysis of fracture interference revealed that hydraulic fracture system damage was, most likely, due to stimulation fluid flooding, into depleted fracture systems around parent wells, resulting in a reduction in the effective fracture area. The team proposed a number of options to mitigate the impact of fracture interference, including refracturing the existing producing well wi...
متن کاملGas Flow Behavior of Nanoscale Pores in Shale Gas Reservoirs
The gas transport in shale nanopores is always one of the major concerns in terms of the development of shale gas reservoirs. In this study, the gas flow regimes in shale nanopores were classified and analyzed according to Knudsen number. Then the gas flow model considering Darcy flow, slip flow, transition flow, molecular free flow and adsorption effect was proposed to evaluate the gas flow be...
