Chapter 24 Drilling, construction, and completion of natural hydrogen exploration and production wells: emphasizing long-term well integrity

Abstract
As global energy demand increases, transitioning from fossil fuels to sustainable green energy sources is becoming more critical. Hydrogen, a clean energy source, is expected to play a key role in accelerating this transition. Natural hydrogen presents a significant opportunity in the energy sector as a clean alternative to traditional fossil fuels. However, developing natural hydrogen reservoirs poses unique challenges, particularly in subsurface exploration, drilling, well design, and construction for safe extraction and production operations. Hydrogen’s distinct physical and chemical properties, such as low molecular weight, high diffusivity, and flammability, necessitate advanced techniques in drilling and well design. These techniques must ensure containment and safe production processes with the highest level of integrity.
Drilling and completing hydrogen wells require special attention. Unlike conventional hydrocarbon wells, hydrogen wells must account for hydrogen’s chemical reactivity, its interaction with wellbore materials, completion hardware, and the surrounding formation (e.g., rock, cement). The impact of thermo-mechanical behavior, especially in dynamic situations during production operations with changing conditions (e.g., pressure, temperature), including the potential for leaks, must also be considered. Hydrogen can also cause metals to become brittle, posing challenges in selecting materials for wellbore construction and completion to maintain safe production operations. Innovations in drilling fluids, casing materials, and advanced completion techniques are essential for safely and economically extracting natural hydrogen from its reservoirs.
This chapter provides an overview of natural hydrogen, its reservoir characteristics, and the framework for drilling, constructing, and completing natural hydrogen exploration and production wells. It addresses the challenges of drilling exploration wells, and completing production wells, focusing on developing an engineering framework for designing and constructing these wells to ensure long-term well integrity. The chapter reviews and synthesizes wellbore integrity issues, detailing the causes of well integrity loss, the challenges encountered, and the associated risks. It proposes a 646comprehensive engineering framework for designing, drilling, completing, and constructing natural hydrogen exploration and production wells. This framework offers guidance on drilling techniques, material selection, cementing practices, and real-time monitoring systems. Through a thorough review, this work aims to provide insights into harnessing natural hydrogen as a sustainable green energy resource.
