Hydraulic fracturing of shale formations in the United States has led to a domestic energy
boom. Currently, water is the only fracturing fluid regularly used in commercial shale oil and …

The concept of increased methane recovery with simultaneous CO 2 sequestration in
unconventional reservoirs like gas shales has been studied extensively. A clear …

Successfully creating multiple hydraulic fractures in horizontal wells is critical for
unconventional gas production economically. Optimizing the stimulation of these wells will …

Natural gas from tight shale formations will provide the United States with a major source of
energy over the next several decades. Estimates of gas production from these formations …

Unconventional oil reservoirs have become an increasingly essential resource for energy in
recent years. Despite the massive oil reserves in these reservoirs, as well as the current …

Although research on CO 2 injection in shale gas reservoirs has been focused for enhanced
gas recovery (EGR) and CO 2 storage, previous studies have not examined both multi …

For decades, scientists and engineers have been investigating and describing storage and
transport mechanisms in geological porous media such as reservoir rocks. This effort has …

In conventional permeable media, once pore volume (PV) is known, the amount of fluid-in-
place can be estimated. This is because the fluid is locally homogeneous, pores are …

Production from shale-gas reservoirs plays an important role in natural-gas supply in the
United States. Horizontal drilling and multistage hydraulic fracturing are the two key …

We performed laboratory friction experiments on shale samples from three hydrocarbon
reservoirs to assess compositional controls on fault slip behavior accompanying hydraulic …
