Therefore, the number of perforation and the formation properties should be considered in designing the limited entry fracturing for better estimation of the fracture parameters and the improvements.
The ways of its formation and its entry into alcohol covered the following: formation of methanol during the cooking of beet and then entered into alcohol products along with steam;
