Laboratory testing

Definition

Laboratory testing refers to the systematic analysis conducted in a controlled environment to assess the physical and chemical properties of materials, particularly in relation to geological samples. This process is vital for understanding the characteristics of geothermal reservoirs, allowing engineers to evaluate their potential for energy production. Laboratory testing helps identify the composition, thermal conductivity, permeability, and other important properties of geological formations.
