The utilization of specific additives aids in maintaining open fractures, thereby improving the flow of gas into the wellbore. An advanced fracking technique involves the ability to drill multiple horizontal wells (up to 40) from a single vertical well pad. ...

Shale is a common type of tight reservoir that is composed of extremely fine-grained, sedimentary rock and may contain oil or natural gas – referred to as "shale oil" or "shale gas". Like all hydrocarbons, they formed over millions of years, when organic material (plants and micro-organisms) was buried and subjected to increasing heat ...

The majority of Bakken Shale oil production has been from a four-county area of western North Dakota – Dunn, McKenzie, Mountrail, and Williams. This area is often called "the kitchen of the
How is Shale Gas Produced? Shale gas formations are "unconventional" reservoirs – i.e., reservoirs of low "permeability." Permeability refers to the capacity of a porous, sediment, soil – or rock in this case – to transmit a fluid. This contrasts with a "conventional " gas reservoir produced from sands and carbonates (such as
The shale gas boom revolutionized the energy sector through hydraulic fracturing (fracking). High levels of energy production force communities, states, and nations to consider the externalities and potential risks associated with this unconventional oil and natural gas development (UOGD). In this review, we systematically outline the environmental, economic, and anthropogenic …
h2 h2 h2; About. As exciting as this is, we know that we have a responsibility to do this thing correctly. After all, we want the farm to remain a place where the family can gather for another 80 years and beyond.
Area A is located in the northwest of the ST Basin. Oil and gas exploration in this area began in the early 1980s and has achieved great results [].The structurally stable area in Area A was selected as the core work area, and 18 wells were deployed in this area based on production needs, including 12 vertical wells and 6 test wells, and high-quality oil flow was …

Oil shale, also referred to as "oil-bearing shale," is a sedimentary rock rich in solid organic matter characterized by fine layering and combustible fine-grained sediment (Wang et al. 2012; Li 2012).Under conditions of low-temperature retorting, it can yield shale oil resembling petroleum (Su et al. 2022).Upon further processing via physical and chemical methods (Lee et …
The development of shale oil and gas resources in a target block requires comprehensive consideration of the first-level guarantee indicators such as science and technology (A), capital (K), talents (L), reserves (S) and ecological environment (E), as well as more than 10 s-level indicators and a number of third-level indicators, in order to ...
Shale is a fine-grained sedimentary rock, with smaller spaces or pores containing gas, and these spaces are relatively unconnected to each other. Therefore natural gas does not flow easily through shale. Estimates of the volume of shale gas can be expressed in different ways. 'Resource estimates' refer to the amount of natural gas that ...
Hydraulic fracturing – commonly known as fracking – is the process used to …
Argentina is a particularly noteworthy example, as it is believed to possess the second-largest shale gas deposits and fourth-largest shale oil deposits in the world (Mares, Reference Mares 2014b; Sierra, Reference Sierra 2016). Interest in Argentina's shale resources has been strong following a significant shale resource discovery in 2011 by ...

The first extraction of shale oil and gas via the process of hydraulic fracturing was carried out in the 1940s. However, it was not until the 2000s that this ...
The total oil generation rate and gas generation rate of pure shale are higher than those of shale with a silty interlayer, and the exchange point between the oil expulsion rate and retention rate ...
In an attempt to find out if and how shale gas could be exploited in a sustainable way, this …
How does hydraulic fracturing (fracking) and horizontal drilling make natural gas trapped in shale rock formations financially feasible and accessible? Shale Gas. Shale is a compressed fine-grained type of sedimentary rock. It was formed from mud silt, clay, and organic matter. Shale gas is natural gas trapped within tiny pore spaces in shale ...
Different from the conventional oil reservoirs, the primary storage space of shale is micro/nano pore networks. Moreover, the multiscale and multi-minerals characteristics of shale also attract increasing attentions from researchers. In this work, the advances and challenges in the development of shale oil are summarized from following aspects: phase behavior, flow …
Energy demand is increasing radically with the development of the world economy, resulting in an imbalanced energy supply and demand contradiction [1].Currently, unconventional oil and gas, especially shale oil and gas, have become 'hot' development targets owing to their vast resources [2], [3].In 1821, the United States drilled the first shale gas well in the Dunkirk …
The USGS Energy Resources Program has studied oil shale resources of the United States, with a significant effort on the Eocene Green River Formation of Colorado, Utah, and Wyoming. This formation contains the largest oil shale deposits in the world. Oil shale, despite the name, does not actually contain oil, but is a precursor of oil that is converted to …
