Shales and mudstones in that basin are compressed by horizontal forces with minor heating. These forces and heat modify the clay minerals in the shale and mudstone.Sedimentary Rocks. Sedimentary rocks (layered rocks) are made by the deposition of particles carried in air or water and by the precipitation of chemicals dissolved in water. These particles and chemicals come from the weathering (breaking apart in place) and erosion (carrying away and breaking apart while moving) of rocks on the Earth’s surface.Jun 7, 2023 · 10. In-situ shale extraction deposits harmful byproducts underground, which affect water sources and the environment. In situ shale extraction is a method of extracting shale oil that differs from conventional practices in that it does not involve the prior extraction of shales before heating. Breccia forms where broken, angular fragments of rock or mineral debris accumulate. One of the most common locations for breccia formation is at the base of an outcrop where mechanical weathering debris accumulates. Another is in stream deposits a short distance from the outcrop or on an alluvial fan. Some breccias form from debris flow deposits.Closing thoughts • XTO approached XOM about merger— implications about cost, competitiveness, environmental & legal battles pending • Hungary play failed & XOM exited • Piceance basin play is non-commercial to date • XOM feels that it needs to learn from XTO, but may not be able to retain employees •ExxonMobil came late to the shale …The geochemical characteristics of shallow groundwater are essential for environmental impact studies in the shale gas production area.
