A damage model for fracking [PDF]
, 2015 Injections of large volumes of water into tight shale reservoirs allows the extraction of oil and gas not previously accessible. This large volume "super" fracking induces damage that allows the oil and/or gas to flow to an extraction well. The purpose of this paper is to provide a model for understanding super fracking.

Energies, 2021 The Chang 7 continental shale oil reservoir is tight. The recovery factor is extremely low, the remaining oil is very high, and injecting water to improve oil recovery effectiveness is too hard.

Dielectric microscopy with submillimeter resolution [PDF]
Applied Physics Letters, 91, 222909 (2007), 2007 In analogy with optical near-field scanning methods, we use tapered dielectric waveguides as probes for a millimeter wave vector network analyzer. By scanning thin samples between two such probes we are able to map the spatially varying dielectric properties of materials with sub-wavelength resolution; using a 150 GHz probe in transmision mode we see ...

Simulation of CO2 enhanced oil recovery and storage in shale oil reservoirs: Unveiling the impacts of nano-confinement and oil composition [PDF]
CO2 injection into oil reservoirs is expected to achieve enhanced oil recovery along with the benefit of carbon storage, while the application potential of this strategy for shale reservoirs is unclear. In this work, a numerical model for multiphase flow

The Economic and Budgetary Effects of Producing Oil and Natural Gas From Shale [PDF]
, 2014 [Excerpt] Recent advances in combining two drilling techniques, hydraulic fracturing and horizontal drilling, have allowed access to large deposits of shale resources—that is, crude oil and natural gas trapped in shale and certain other dense rock ...

The Price Responsiveness of Shale Producers: Evidence From Micro Data [PDF]
, 2021 Shale oil producers respond positively and significantly to favourable oil price signals. This finding is established using a novel proprietary data set consisting of more than 200,000 shale wells across ten U.S. states spanning almost two decades.

Branching of Hydraulic Cracks in Gas or Oil Shale with Closed Natural Fractures: How to Master Permeability [PDF]
Proceedings of the National Academy of Sciences Jan 2019, 116 (5)
1532-1537;, 2018 While the hydraulic fracturing technology, aka fracking (or fraccing, frac), has become highly developed and astonishingly successful, a consistent formulation of the associated fracture mechanics that would not conflict with some observations is still unavailable. It is attempted here.

In-situ laser retorting of oil shale [PDF]
, 1977 Oil shale formations are retorted in situ and gaseous hydrocarbon products are recovered by drilling two or more wells into an oil shale formation underneath the surface of the ground.

Temperature Effect on Interactions of Oil Droplet with Water-wetted Shale Kerogen at Reservoir Temperatures [PDF]
arXiv, 2020 Understanding the thermodynamics of the interfacial interactions between oil and kerogen is imperative for recovering hydrocarbon in tight reservoirs, especially in unconventional shale that retains abundant hydrocarbon in kerogen nanopores. The temperature effect on the interactions of light oil with a type II kerogen in water was investigated using ...

Employment and Wage Changes in Oil-Producing Counties in the Bakken Formation, 2007-2011 [PDF]
, 2013 The Bakken Formation is an oil-producing shale formation underneath North Dakota, Montana, and parts of Canada. In recent years, horizontal drilling and hydraulic fracturing techniques, combined with higher prices for crude oil, have led to rapid ...
