The sand control techniques normally used are divided into sand control without screen and sand control with screen.The way shaliness affects a log reading depends on the amount of shale and its physical properties. It may also depend on the way the shale is distributed in the formation. Shaly material can be distributed in the formation in three ways: Shale can exist in the form of laminae between which are layers of sand.

For many years, the most common acid practice for sandstone acidizing is based on mud acid and dolomite formations using hydrochloric acid. During various stages of sandstone acidizing, different acids react with different minerals, and interactions of minerals with acids are an origin for precipitation reactions, which can be possibly deleterious as they may reduce reservoir permeability.According to local stories, the immense sandstone formations were considered sacred ground and that meant that even rival tribes laid down their weapons when entering the Garden of the Gods.
