The book discusses the evolution of technical knowledge required from geoscientists, engineers, and managers to develop a detailed and integrated approach to the design and execution of a horizontal well.
Through 2001, more than 34,777 horizontal wells had been drilled in 72 countries spanning the globe.
Today, horizontal and extended-reach wells are used to overcome various challenges imposed by reservoir geometry, fluid characteristics, economic conditions, or environmental constraints, including:
• coning (gas or water)
• waterflood conformance
• improved recovery from thin beds
• economic and technical limitations (e.g., offshore limitations on the number of slots)
• environmental restrictions
• heterogeneous reservoirs (e.g., fractured or restricted flow units)
• recovery from tar sands
AAPG’s Horizontal Wells
highlights the changes in our understanding of petroleum reservoirs and the type of knowledge required to move beyond the limitations of vertical wells to a horizontal perspective.
