METHODS OF ENHANCING FLUID LOSS CONTROL USING ADDITIVES |
摘要 |
In some instances, a fluid loss control enhancement additive may synergistically work with lost circulation materials ("LCM") to arrest lost circulation in wellbores where LCMs alone have been ineffective. For example, a method may involve treating a wellbore penetrating a subterranean formation with a pill comprising an aqueous base fluid and a lost circulation material; observing fluid loss from the wellbore to the subterranean formation while treating the wellbore with the pill; and adding salt, a swellable polymer, and fibers to the pill. |
