Type Sedimentary Rock Origin Detrital/Clastic Texture Clastic; Very fine-grained (< 0.004 mm) Composition Clay minerals, Quartz Color Brown Miscellaneous Blocky Depositional Environment Flood Plain, Lake (away from shore), Mid-continental Shelf, Delta, Tidal Flat, Lagoon, or Deep Marine Type Sedimentary Rock Origin Detrital/Clastic Texture Clastic; Very fine-grained (< 0.004 mm) Composition ...The pore types of the shale include organic pores, intergranular pores of clay minerals, brittle mineral pores (intercrystalline pores, secondary dissolution pores), among which the organic pores ...The drilling of clay-rich formations, such as shale, is an extremely demanding technical and technological process. Shale consists of mixed clay minerals in different ratios and in contact with water from drilling mud. It tends to swell and cause different wellbore instability problems. Usually, the petroleum industry uses various types of salt and/or …

Shale is characterized by its tendency to split into thin layers less than one centimeter in thickness. This property is called fissility. Shale is the most common sedimentary rock. The term shale is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the narrower sense of clay-rich fissile … See moreThe best type of gravel for the top layer of a gravel driveway includes crushed shale, limestone, granite and concrete. There are different types of gravel in various colors to have an aesthetic appeal. Additional Tips for Gravel Driveways. Choosing the right gravel is important, but proper site preparation is even more vital.
