Pressures experienced in the wellbore also affect the strength development of the cement. Formation characteristics. The composition of formations can present compatibility problems. Shale formations are sensitive to fresh water and can slough off if special precautions are not taken, such as increasing the salinity of the water.

Shale Rock: Geology, Composition, Uses

Shale is a fine-grained rock made from compacted mud and clay. The defining characteristic of shale is its fissility. In other words, shale readily breaks into thin layers. Black and gray shale are common, but the rock can occur in any color. Shale is commercially important. It is used to make brick, pottery, tile, and Portland cement.
