Petroleum is a naturally occurring mixture of hydrocarbons found in geological formations that is refined to produce fuels like petrol, diesel and paraffin. The demand for petroleum exploration and drilling has consistently grown over the years, as petroleum is a major energy source. Petroleum exploration involves substantial geological evaluation through seismic data and subsurface analyses. It is being fused with advanced geomechanical simulations for efficient detection and evaluation of petroleum reserves. Drilling and production processes, are being modernized for maximum resource utilization, better affordability and low ecological impact. This book covers varied aspects of petroleum exploration, drilling and production in a comprehensive way. The various studies that are constantly contributing towards advancing technologies and evolution of this field are examined in detail. Petrochemical engineers, geologists, students and researchers will benefit alike from this book.
