Fundamentals of Sustainable Drilling Engineering

Hydrophobic silica nanoparticle-stabilized invert emulsion as drilling fluid for deep drilling

“…Modern drilling fluid (also called drilling mud) is an essential part of the rotary drilling system. The successful completion of a hydrocarbon well and its cost depend on the properties of drilling fluids to some extent (Bourgoyne et al 1986;Hossain and Al-Majed 2015). Therefore, the selection of a suitable drilling fluid and routine control of its properties are the concern of the drilling operations (Hossain and AlMajed 2015).…”

“…Drilling technology has been widely used in the applied sciences and engineering, such as manufacturing industries, petroleum industries, pharmaceutical industries, aerospace, research laboratories, and from small-scale laboratories to heavy industry (Hossain and Al-Majed 2015). Modern drilling fluid (also called drilling mud) is an essential part of the rotary drilling system.…”

Drilling Fluids for Deepwater Fields: An Overview

“…In this way, new deepwater discoveries around the world become challenging tasks of technical, operational, environmental, and economic issues, where many of those tasks are focused on the selection, development, and application of drilling and completion fluids technologies [1][2][3][4][5].…”

“…Key cost drivers for offshore drilling include water depth, well depth, reservoir pressure and temperature, field size, and distance from shore. Drilling fluids can represent from 15 to 18% of the total cost of well drilling but may cause 100% of drilling problems [4][5][6][7][8][9][10].…”

“…The operational issues and concerns related to the drilling fluid design and application for deepwater fields are generally well known: narrow pore/fracture pressure gradient margins, wellbore stability, clay swelling, gas hydrates formation, formation damage, salt formations, lost circulation, stuck pipe, cuttings transport, and environmental and safety aspects [1][2][3][4][5][6][7][8][9][10][11]. The design, selection, and application of the right fluid system or additives require balancing each of these issues with regard to their impact on the deepwater drilling operation.…”
