“…Baker Hughes has combined the polyamine compound with the cloud point of the polymeric alcohol and the chemical plugging of aluminum, and the PERFORMAX highperformance water-based drilling fluid was developed, which utilizes the collective effect of nano-polymeric plugging agent (MAX-SHIELD), aluminum-based chemical plugging agent (MAX-PLEX), shale hydration inhibitor (MAX-GUARD), and polymer coating agent (NEW-DRILL) to plug shale pores and micro-fractures, and prevent fluid pressure penetration and filtrate intrusion. The PERFORMAX drilling fluid has the advantages of strong inhibition, high temperature stability, reservoir protection, and environmental friendly, and it can meet the discharge requirements of the Gulf of Mexico stipulated by the US Environmental Protection Agency [15]. EXXON has developed EHT non-toxic high-temperature brine or seawater-based drilling fluid for land and marine drilling [16].…”

Oil and gas explorers around the world have gradually shifted their attention to complicated geological reservoirs, such as deep or ultra-deep, unconventional, and deepwater reservoirs. Against this trend, drilling fluids must meet stricter requirements, making the drilling in such reservoirs safe, fast, efficient, and environmental-friendly. Recent years has seen the emergence of environmental-friendly, high-performance waterbased drilling fluids, which boast comparable performance as oil-based drilling fluids. Some high-performance water-based drilling fluids have been developed specifically as per the technical requirements of drilling into complicated geological reservoirs. However, China lags far behind in the development of environmental-friendly, highperformance water-based drilling fluids. This paper summarizes the latest technical progress on environmental-friendly, high-performance water-based drilling fluids at home and abroad from three aspects, namely, environmental-friendly, high-performance water-based drilling fluids, environmental-friendly drilling fluid additives, and environmental evaluation methods for drilling fluids. Moreover, the development trend of the technology of environmental-friendly, high-performance water-based drilling fluids was discussed, providing a reference for further research into environmentalfriendly, high-performance water-based drilling fluids.

“…Over the past years, many solutions have been proposed to inhibit clay hydration and dispersion through a variety of mechanisms, such as inorganic salts of potassium chloride and sodium chloride, formates, polymers, asphaltenes, sugars and sugar derivatives, polyglycerols and glycols, silicates [4][5][6][7]. However, these approaches bring only marginal success [8]. Among these solutions, KCl with high concentration probably is the mostly applied solution due to its effective inhibition performance.…”

Based on the rules of designing high performance shale inhibitors, bis-(hexamethylene)-triamine was introduced as a potential shale inhibitor in water-based drilling fluid. The inhibitive properties were evaluated through bentonite inhibition test, cuttings hot-rolling dispersion test and particle distribution measurement. The compatibility with common drilling fluid additives was investigated. Bis-(hexamethylene)-triamine effectively inhibited shale swelling and dispersion, superior to potassium chloride and polyetherdiamine POP230, and was compatible with normal additives in drilling fluid. The inhibitive mechanism was analyzed via XRD, zeta potential measurement, FT-IR, water adsorption test and TGA. The results showed that electrostatic interaction, hydrogen bonding and hydrophobic shielding effect contributed to the inhibition with synergetic effects, whereas the protonation of multi-amine groups played a vital role in the action.

“…However, OBM are still perceived by some to be the best choice for drilling wells where reactive shale rock, tortuous well paths, and/or extended reach targets are a reality of the project. 4 OBMs have strong oil-wetting characteristics and these characteristics are beneficial to drilling operations, especially for inhibition and lubricity. Conventional invert emulsion drilling muds are typically designed for high electrical stability (i.e., ES >1000) and strong oil-wetting characteristics.…”

TX 75083-3836, U.S.A., fax 1.972.952.9435. AbstractIdeally, a reservoir drill-in fluid (RDF) possessing both an oil external phase for drilling and a water external phase for completion would provide the ideal solution for drilling and completing a well. Through the manipulation of surfactant chemistry, a novel reversible invert emulsion drilling system, which provides both attributes, has been developed. During drilling, an operator can utilize the reversible oil-based mud to take advantage of the commonly accepted properties that enhance the drilling efficiency and then convert this system to a water-based fluid to improve the completion efficiency.The amine-based surfactants used in the reversible invert system are strong emulsifiers in an alkaline medium; however these same emulsifiers become more common direct oil-inwater emulsifiers in the presence of protonating agents such as acid. This process of protonation and deprotonation of emulsifiers controls the emulsion phase of this drilling system and thereby, the oil-wetting and water-wetting characteristics of the subsequent filtercake and entrained solids. As the bridging agents in filtercake are commonly calcium carbonate, once water-wet (in presence of acid) promote clean-up and thus, are readily consumed by common acids that may be utilized during the completion phase.This system was field trialed with success for drilling and completing an injector in the first quarter of 2000. Since this initial application, numerous completions have utilized this reversible invert RDF system. This system has been successfully applied to a variety of completions, in particular: injectors and producers, openhole gravel-packs (OHGP), expandables and standalone as well as various environments and reservoirs. Theoretically, this system also provides advantages with respect to common cementing and environmental issues.This paper presents the development of this multi-purpose drilling and completion system and discusses the application of this technology to adapt to the challenges of evolving global completion complexity.Several case history examples are presented from selected completions. The paper includes the laboratory pre-planning and field data illustrating the concerns and the development of a solution with respect to drilling and clean-up.
