| titleOfInvention | Use of high ratio aqueous alkali silicates in drilling fluids |
| abstract | An improved drilling and completion fluid can be used in subterranean drilling for oil and gas. Sodium silicate and potassium silicate-based drilling fluids are commonly used drilling fluids with the notable attributes of exceptional shale stabilization characteristics coupled with exceptional environmental performance. Environmental and wellbore stabilization characteristics are improved by using high ratio aqueous silicates wherein ratio is defined as the molar ratio of SiO2:Me2O, where Me is an alkali and is most commonly sodium or potassium (i.e. Na2O and K2O). For high ratio aqueous alkali silicates, the molar ratio of SiO2:Me2O can range from just over 4.0 to about 12Ø |
