“…Autonomous directional drilling using a mud motor and rotary steerable systems is also an area that has received attention from the process systems and control community using MPC technology. 98,99 These systems are often formulated and solved as Mixed Integer Quadratic Programs due to the presence of binary and continuous quantities. Satisfactory trajectory control of the drillstring while satisfying operational constraints has been achieved as detailed in Zhao et al 99 It is thus evident that the applications of the process control techniques discussed herein show good potential for increased drilling efficiency, safety and reduced cost if they are well integrated into drilling processes.…”

The ever-increasing quest to identify, secure, access and operate oil and gas fields is continuously expanding to the far corners of the planet, facing extreme conditions towards exploring, securing and deriving maximum fluid benefits from established and unconventional fossil fuel sources alike: to this end, the unprecedented geological, climatic, technical and operational challenges have necessitated the development of revolutionary drilling and production methods. This review paper focuses on a technological field of great importance and formidable technical complexity -that of well drilling for fossil fuel production. A vastly expanding body of literature addresses design and operation problems with remarkable success: what is even more interesting is that many recent contributions rely on multidisciplinary approaches and reusable Process Systems Engineering (PSE) methodologies -a drastic departure from ad hoc/one-use tools and methods of the past.The specific goals of this review are to first, review the state of art in active fields within drilling engineering, and explore currently pressing technical problems, which are in dire need, or have recently found, PSE-and/or CFD-relevant solutions. Then, we illustrate the methodological versatility of novel PSE-based approaches for optimization and control, with an emphasis on contemporary problems.Finally, we highlight current challenges and opportunities for truly innovative research contributions, which require the combination of best-in-class methodological and software elements in order to deliver applicable solutions of industrial importance. Well drilling in the oil and gas industryThe annual increase in global energy demand and the diverse applications of conventional & unconventional oil and gas resources are indicative of the fact that these resources will continuously remain relevant to humanity in the far future. With increasing climate change concerns, natural gas already provides a promising transition between some oil-based fuels and renewables in the long run, despite its well-known transportation difficulties. 1 It can be further argued that natural gas represents an economically attractive option for electricity generation (particularly in the US where shale gas is naturally abundant) with significantly reduced greenhouse gas emissions compared to coal; thus increasing its market demand. 2 These reasons have warranted the advancements in technologies of
