The specialized book "Investigations into Carrier Damage from Drilling Fluids and Treatment Liquids" offers a comprehensive analysis of the effects of drilling fluids and treatment liquids on the permeability of carrier rocks in oil and gas reservoirs. It explains how the fluids used during drilling operations and subsequent treatments can impair the original carrier permeability, a phenomenon referred to as carrier damage. The book discusses the physical and chemical reactions that can occur between the drilling fluids and the carrier rock, as well as the mechanisms that contribute to stabilizing the borehole. Another focus is on hydraulic fracturing treatment, where high-pressure fluids are used to create fractures in the carrier rock and improve the permeability of the reservoir. The detailed examination of these processes is of great importance to professionals in the oil and gas industry to optimize reservoir productivity.
