Petroleum Coring

Petroleum coring involves extracting a cylindrical sample of rock from the earth during oil and gas exploration. This sample, called a core, provides valuable information about the underground geology, such as rock types, porosity, permeability, and the presence of hydrocarbons. Coring helps geologists and engineers assess whether a reservoir contains enough extractable oil or gas and guides drilling decisions. The process uses specialized drill bits to carefully remove the core, which is then analyzed in labs. Coring is essential for understanding subsurface conditions and optimizing the development of oil and gas fields.
