Mudstone is a common sedimentary rock with a very fine-grained texture that is sometimes called by various other names such as mudrock, argillite, claystone and siltstone. Shale is also a type of mudstone rock but differs from most other kinds of mudstones in that it is made up of visible layers.

Apr 29, 2022 · Shale oil is a high-quality crude oil that lies between layers of shale rock, impermeable mudstone, or siltstone. Oil companies produce shale oil by fracturing the rock formations that contain the layers of oil in a process known as "fracking." Learn how shale oil works, its pros and cons, and how it compares to crude oil. To understand reservoir properties of shales, rock-physics models are very important. Rock-physics models describe the relationships between reservoir properties and the elastic properties, calibrated by well log and core data at well locations. The specific rock-physics model to be used depends on the rock type and complexity of the rock.Shale, any of a group of fine-grained, laminated sedimentary rocks consisting of silt- and clay-sized particles.

In shales with identical mineral compositions, the finer the grain size, the more conducive to fracture development it is, and vice versa (Zeng and Xiao, 1999, Li et al., 2009).To understand reservoir properties of shales, rock-physics models are very important.

"When shale forms, it’s originally mud that gets deposited at the bottom of an ocean" Danielsen said. "As that gets buried and pressed down by more and more sediment, eventually, all that mud will compress, all the water will be squeezed out of it, and it will … Shale is a fine-grained sedimentary rock that forms when silt an CrownRock is a US-based oil and gas producing joint venture comprising CrownQuest Operating and Lime Rock Partners. Last month, Reuters reported that a potential sale of CrownRock could value it ...It is not clear how shale gas production in the UK would affect greenhouse gas emissions. A study for the UK Government in 2013 indicated that the impact would be small if production was well-regulated, but also warned that global emissions could increase if imports of natural gas were only diverted to other consumers. Devon is one of the biggest independent shale explorers in the U.S
