New Ultralightweight-Cementing Technology Combines Benefits of Current Leading Methods

Historically, the industry has either foamed base cement with nitrogen or added microspheres to the slurry to create ultralight cement slurries. While both of these technologies are considered premium solutions and have been used successfully for a number of years, they each have distinct advantages and limitations when compared to one another. While each is ideal for certain situations, neither one can be used to cover the ever-increasing spectrum of challenges.
