Gas hydrate occurs in reservoirs a solid form. At present, the conventional exploitation method is to decompose and then extract resulting gaseous gas. Therefore, occurrence law of gas reservoir great significance for study seepage productivity. Adsorption, as an important mode, has been widely concerned research on shale reservoirs. However, adsorption problem not received enough attention. In...

Shale gas and oil are significant unconventional energy resources in the United States. Because of their low porosity and permeability, as well as the complex pore systems in organic rich shale formations, their petrophysical properties are not fully understood. Further, it is well known that wettability influences many aspects of reservoir characteristics, especially hydrocarbon storage and re...

The US shale exploration and production (E&P) industry has grown since 2007 due to the development of new techniques such as hydraulic fracturing and horizontal drilling. As a result, the share of shale gas in the US natural gas production is almost 50%, and the share of tight oil in the US crude oil production is almost 52%. Even though oil and gas prices decreased sharply in 2014, the product...

Testing of 1701 water wells in northeastern Pennsylvania shows that methane is ubiquitous in groundwater, with higher concentrations observed in valleys vs. upland areas and in association with calcium-sodium-bicarbonate, sodium-bicarbonate, and sodium-chloride rich waters--indicating that, on a regional scale, methane concentrations are best correlated to topographic and hydrogeologic features...

The main goal of this paper is to use the multilayer perceptron neural network to suggest a 3D cube of the Total Organic Caron (TOC) in the lower Barnett shale gas reservoir. 3D Poststack seismic data recorded near two horizontal wells drilled in the lower Barnett formation are used as an input to train the neural machine, while the calculated acoustic impedance from sonic and density well-logs...

After volume fracturing of horizontal wells in shale gas reservoir, an extremely complex fracture system is formed. The space area the reservoir reconstruction reservoir. geometric parameters such as crack length, width, height, and characteristic permeability conductivity proposed for a single conventional are insufficient to describe characterize network after fracturing. In this paper, discr...
